Is Lithium-ion the Ideal Battery?

Reading this: «Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery’s life.» such as what we hear from PC sellers about their products long-life maintenance. Cycles of complete discharging and recharging are only for hardware and software calibration, not intended for battery life.
Thanks for the explanation.

The search for a battery to power our electric cars should include an all liquid battery.  Instead of having to charge the battery at home or at a charging station, I think a better idea would be to have a storage system where the liquid battery would be stored in the car untill the charge is spent and then like going to the gas station you would pump out the spent liiquid battery and put in a charged liquid battery.  Instead of having to wait until the battery is charged(like the present situation) you would just wait until the battery(liquid) is exhanged.  Another option would be to exchange a spent physical battery for unspent one. What do you think?

My comment is. If there is a big market for this product.
Very much interested if finding out the potential to commercialize this particular Battery
of lithium in global proportion

What is the mechanism that causes some types of Lithium batteries to violently
explode ?
What are the statistics of thses Lithium batterie exploding ?
would 1 per thousand be correct ?

m.shen

LiON battery would explode if the reaction create some hidrogen and in the expansion two contact give a short circuit. If the battery was made by low quality processes the percentage can be higher, but in normal circumstances, precaution like described in this article, the percentage is better: one on millions of units.

I just got a lithium ion battery powered Dyson vacumn. From what I understand you are saying, it’s best to prolong its life by 1) not fully charging it each time - only charging it to about 80% of full capacity   and 2) storing it at 40% charge in a cool place when not in use.  Is there any other practical advice?
thank you for your articles.

Why do Lithium_ion_batteries have three electrical contacts, i.e.  + (plus), -(minus) and an unmarked one? Is the latter conected to the charging (safety) circuit?

It is not clear to me the sentence “The maximum charge and discharge current on most packs are is limited to between 1C and 2C”. “1C and 2C” should be “1A and 2A” (amps), since it refers to a current?

The C rating of a battery is its discharge rate (or it can also represent a charge rate).  It is defined as the amount of current it can safely discharge over a period of time expressed in multiples of the batteries total rated capacity.  A battery’s C rating is equivalent to it’s mah rating sustained for one hour. For example a 3000 mah battery being discharged at 1C, or 3000ma, will last one hour at that discharge rate, this equals 1C… At 0.5C (1500ma)  it will last for 2 hours.  That same battery being discharged at 2C (6000ma) would last 30 minutes, etc.  The same principle applies to charge rates as well.  Different technologies can handle different rates.

I would like to know if more research is done into other tehnologies (non-lithium) because this element (Lithium) is in low quantities on Earth thus beeing unwise to over-develop something based on a rare material (just a very few countries have lithium reserves). When I think what will be to replace all present petrol/diesel cars just from one developed country with lithium based energy storage will requiure more than we can find on entire planet.
An ideal battery… questionable, for the moment in small apliances yes, in next 30-40 years of course not.

I am concerned about the weather.  Will freezing affect the Lithium-Ion battery on my Travel Scooter (wheelchair). I know I have to protect it from the heat.  I have a spare battery, but both batteries have been left in the rental car exposed to the cold.

Andrew,
Lithium is not rare, many countries have large reserves.
Midge,
Freezing should not hurt the battery but it may reduce it’s capacity when cold.  They should be warmed up some before charging to take more charge.

Thanks JP,  I’ll be sure to bring my batts to room temp b4 charging & won’t put them in the car until just b4 I leave, so they won’t be too cold to provide optimum capacity. 

BTW, I have a spare because they quit without warning, unlike gel cells which give a fair reading of remaining charge.  Is there an affordable & convenient device available that I can use to read the Li-Ion?

Can a Li-ion battery be used in a cordless drill which calls for a NiCd? Are they interchangeable?

Ross: thats a big NO! The drill may work with a Li-ion battery if it fits, chances are it wont. But you cannot use a NiCd charger with a Li-ion battery. Lithium batteries are very sensitive and need specific chargers to control the amount of current etc.

If your drill is NiCd i suggest you stick to NiCd or NiMh batteries. And if you really want a Li-ion battery for whateva reason, go buy a Li-ion drill.

I am having problems with a 12 volt Li-ion drill & saw.  Especially in colder weather the batteries just shut down - the battery overload protection just cuts in.  I get this problem with the smaller 1,5 Ah batteries but not with the 3ah ones.  Could the batteries of been damaged by being kept cold - they live in my van so could be -5 at night ?.  Or could the batteries have developed a fault.

Many tool shops are warning against Li-ion & are reporting lots of problems.

Thank you for your reply BWMichael. But after further research, the answer is at least partially ‘yes.’  Perhaps my question should have been better stated as to ‘physically’ interchangeable. I understand that they require different chargers - and that is very important! I spoke with a DeWalt representative, who told me that the Li-ion and NiCd batteries were physically interchangeable on their cordless tools. And in fact, Porter-Cable makes a line of ‘bare tools’, which are sold without a battery - allowing the user to choose either NiCd or Li-ion. Thanks again for your input!

I would like to remove NiCd bateries out of my 18v pack and replace with Li-ion,
and use the same charger that came with the NiCd. Is this possible We have problems with the NiCd bateries constantly. I have rebuilt NiCd packs before with NiCd batteries.

Hi Andy - NO you CANNOT charge a Li-ion battery in a NiCd charger. Each type requires a very specific charger, and it would be dangerous to attempt to do so.

Using batteries for SMALL Data Centers – what is next ?

Question:  Do you know if APC - American Power Conversion, Eaton Products or the like have or are planning to have Lithium battery based UPS units - Uninterruptable Power Supplies.  APC has the Symmetra system this unit uses “Lead acid” based batteries.  This unit keeps Data Centers running during power outages in our client sites.  Will Lithium be more effective than APC’s current batteries - perhaps price would be too high for the market?  Any ideas?
As the Global Warming effects start to appear in our state… keeping small Data Centers up and running for 24-hours and in some cases 48-hours electrical outages is critical - wee need better technology!
Yes I know about standby electrical fuel/ gas generators… but for some reason (political) this is not a solution.

...please suggest me some comments as soon as possible…..

I have a Makita cordless driver/drill that I use daily in my trade and, living in Iowa, it can be less than 10 degrees F on a regular basis in winter.  What is the effect of freezing on the total number of charge/discharge cycles I can expect in the life of my tool?

I am interested in a nominal 24 volt 44 Ah LiFePO4 battery.  What weight cost, electronics? ? ?

the life of battery ran in low or high temperature depend on the active material and discharging rate.

I need to replace two 12V 4.5Ah NiCd batteries from a 1993 camera.  Camera eats 25w and NiCd were rated to last for 1.25hrs.  I bought a 12V 4800mAh Li Ion.  It does not output enough power to run the camera longer than 30 or 40 seconds.  It still showes 12.3VDC but does not power the cam.  What did I not understand?

we can see that the N-Cd battery is discharging at 0.66C as 3.6A（4.5/1.25) current, the rated power of camera is 25w, rated voltage of camera is 12V, only need 2.0A current is enough.that is the confused point i think.
your information is not enough, what kind of battery it is ,what is the model ,what is the amount ,seriese or parallel.
please give us more information.
I think the battery of different kinds can not be crossed used. the rate of discharging curve is different, the inner resistance is different either.

•Li-ion cells are very sensitive to charging characteristics and may explode if mis-handled.
•Strongly suggest that you use the matched Li-Ion battery charger to recharge the battery pack
•Charging temperature: 0 to 45 degrees Celsius
•Discharging temperature: -20 to 60 degrees Celsius
•Storage temperature: -20 to 45  

I just purchased a Casio Exilim underwater camera for my vacation. I use it for about an hour and then the camera stopped working. I thought the battery had to be charged but then it still did not work. When I checked it again the lithium battery looked like something leaked out of it and my camera will not work.  Can it be that this happens to these types of batteries or can there be something wrong with the camera itself??? Someone please help!!! Thank you!

I suspect that you have a moisture problem !

Hi, i’ve purchase a not original sony li-ion battery for my camera.
After one minute of use I read this message:“Non-standard battery is used. Use the info LITHIUM battery.” and the camera swich off.
The battery is the same in all aspect from the original.
Why does it possible?
Can I do something to remove the message and use it?
R
Ales

Ales: Unfortunately you cannot remove the message and use this battery.

A few companies including Sony and JVC have made their genuine batteries with micro chips inside and the camera is designed to function properly only when the chip is present in the battery.

This is so aftermarket batteries cannot be purchased and you are forced to buy genuine batteries from them which they can charge as much money as they like.

I have to say that the brother up floor is right!

the protector inner the battery is written in original information.

I have a Panasonic ag-bp15p Li Ion camcorder batter that sat in the camera bag for over 8 years.  I charged it and it gave me about 18 minutes to video time.  I recharged it and it gave me about 3 seconds and about 10 seconds later the camcorder shut down,

Is there nay way to chock the battery back to life as I used to do with NiCads.  I am aware of the high voltage and heat protection it has.

I just purchased one on lone.  I wonder if I should have been concerned about shelf life.

Thoughts appreciated.

I really don’t think that 18650 cells are 650 mm long.

Is there a lithium ion batter that could put out enough wattage (1200 MIn.) to power a hair driyer that wouldn’t weigh the same as a small car?

Other than needing to dry hair out in the woods, what is you r application? You might find a heavy duty inverter and sock the wits out of your car engine as it tried to keep up the voltage. I doubt you are going to find any portable cell block to do it.

I should have specified that I want to design a hand-held appliance with a light, durable, long-lasting battery. (And not what you may be thinking. That’s been done.)

Looking to replace 4 “AA” batteries with rechargeable ones for use in a lightweight led array. Nicad rechargeable"AA” only put out 1.2v so I would like a “green” alternative - any suggestions?

Like the article states, Sony commercialized the first rechargeable Li-Ion batteries in the 1990s.  They had big plans for their portable electronic devices of the time, such as the Walkman, and they recognized a practical battery was necessary to enable volume sales.  But lesser known is that Sony acquired this technology from Duracell in theb1980s, after Duracell gave up on it.

I am searching for a vendor who carries a Li-Ion battery pack for my Eton Scorpion Radio.  It is a 2/3 AAA 3 cell.  Can anyone help?

With ref. to the 18650 Li-oin cell, the size is 18mm x 65.2mm according to several sites.

How can I identify chemistry of Lithium cells of my e-scooter’s battery, taking into account that they’re connected in 16S6P configuration, they are cilindrical and they do not have any writing on them?

“lithium is the lightest of all metals,” (in the text)

Metals carry a positive charge.  Hydrogen carries a positive charge too. So Hydrogen is the lightest of all metals, with an atomic mass of only 1, where Lithium is 3.

Is it available 1.5 v output, AA sized Lithium ion battery?
because it would be very useful for high drain devices like digital cameras with flash and ccd sensors

Just as a passing piece of information on the Li-ion aging, I have a Nokia 3510i which I’ve had since 2003. The battery is still the original, stays on most of the time and still has a standby time of about a week. As far as my feeble memory goes the battery still performs roughly as new!
Being ignorant of battery properties I assumed that the longevity was a result of the Li-lion technology. The article would appear to suggest the opposite!

How many failure Ni/Cd cells can be replaced per aircraft battery and is there any limit for replacing the failure cells?

my laptop’s new Li-ion battery, with an impressive time period of more than two hours, just stopped working. I can not understand why… may be it was over-heated!
What I want to ask is Why it stopped working at once as its cells were pretty good?
and If cells are still good, then can it be repaired?

This may be a manufacturing defect of the battery.  We can’t repair the battery and the separator (One of the main component of the cell)  of cell may be the reason for over-heating.  When is it heated? while charging the battery or using the battery?

lithium cell is a battery that i will always recommend because it has helped me a lot,even during the dark days when friends were not there…THANKS TO YOU LITHIUM CELL!!

lithium cell..THE BEST BATTERY I HAVE EVER HAD

In Lithium-cell, The anode is Graphite over copper foil and the cathode is Lithium cobalt oxide and the separator is celgard trilayer material are the main component of the Lithium-ion cell.  The electrolyte is lithium phopho hexa fluride (LiPF6).  these components hemitically sealed in Aluminium can material.

So I have a Samsung Galaxy S III, my question is… Is there a need for an initial charging? Do I have to drain the battery first before the first charge? How do you optimize the battery life?

There is no need to drain the battery, you can do charging as per the instruction given by the supplier.  Need some instruments to do the optimization and It is dangerous without knowing the technique.

I got another new battery and the same happened to it within 16 hours (It stopped working). Both times laptop was very hot (may be because I do not clean often??) and so was the battery. why was the battery so hot?? I’d like to think that system’s heat diffused into the battery!! 7% charge was remaining in battery for the 1st time and 34% remaining 2nd time. Both times laptop was working on battery power, and when the batteries stopped working it shut off like a AC computer whose power plug is pulled suddenly. Now both these batteries do not interact with the laptop. the message that appears on battery icon is “plugged in, charging” but no increase or decrease in the charge level. My laptop is HP Compaq 6910p.
What is the real issue? Fault in laptop or just the heat?

If the battery is bulged is it convenient to reuse after servicing ?

I am looking for a battery solution for Telecom site using lithium ion battery. Can i have a manufacturer.

I am looking for a battery solution for Telecom site using lithium ion battery. Can i have a manufacturer with 2V 1000AH

Please tell me which battery will be more effective with such specyfications?

6300 mAh, 6-cells, Li-Ion with Intel Core i5-3317U (minus: no Li-Polymer)

6070 mAh, 6-cells, Li-Polymer with Intel Core i5-2467M (minus: worse processor which use more energy)

5440 mAh, 4-cells, Li-Polymer with Intel Core i5-3317U (minus: less mAh)

Bulged Li battery can be servicing so we can not reuse.

General Lithium ion battery charger question.

I have a CV4 professional intelligent digital balance charger, my battery is an 8-cell, 12v lithium ion pack. When I made the purchase from CV4 they told me this was the charger I needed. Problem is, I keep going through batteries in my ATV(four wheeler). When looking into this I find stats about my charger that say “li-ion/Polymer cell count 1~6 series.”

My question is, does this seem right for an 8 cell battery? Maybe I don’t fully understand the stats on the charger, the rep at CV4 tells me this is the charger I need…. Why am I going through so many batteries?

@ Stefano Monti
Your assumption was the same used in FAA testing environment for the B787 but has been corrected down to two failures in less than 100’000h since! Lethal. They might have to consider switching back to NiCad with an approx. 50kg weight penalty per battery with no more thermal runaway in cells, which cascaded to the other cells and that resulted in the fire and therefore airplanes being grounded for months now.

May i know which is better or durable ” 18650 lithium-ion battery” or “Li-Ion Polymer”? what is there advantage/disadvantage between the 2?

Anyone knows about Mean Time to First Failure of Li-ion batteries?

18650 Li-ion battery refer the cylindrical cells combination, 18650 refer the size of the cell,
In Li-ion polymer is polymer based separator.

Hi,

Can i use a lithium ion battery charger IC to charge for lithium polymer battery??

has any new battery technology been discovered?

My golf buggy with a lithium battery was immersed in a creek. Would it be safe to try the battery or is it likely to be irreversibly damaged? Thanks

If it didn’t get damaged, it will upon turning on the key!
You must open the cart and inspect (or make inspect) the battery BEFORE turning on the cart.
Post some pictures!

Thanks jumpjack. That’s not good news because the motor was still going when we got it out. We disconnected it, but then a person who stopped to help turned it on. It went briefly and died. There is still water dripping out of it - 5 days now. Other than that there is no visible damage.

Brushless motors are waterproof.
Batteries usually are not…. but maybe just the electronics was burnt and the battery cells are still ok…

So do you think it will be all right to try when dry?

Having a couple of generations in industrial commercial electrics - motors & controls,
I would suggest that you take it to a professional golf or electric motor service.
While the motor and or battery may not be damaged -  or at least minimally -  the controls might have been shorted.  Many (most of the) times they can be dried out. And, the motor can be megged for wetness at the start.  Otherwise, it appears to be guessing with your pocketbook.  Even then you might still be guessing, hopefully you will have reputable service people to deal with.  Best wishes.

Thank you AIG. I’ve found a local repairer who is recommended.

Please keep us up to date!

Will do. Thanks for everyone’s help.

The golf trolley is working! The recommended repairer said the situation was hopeless, but then the golf pro tried it and it all appears fine. However, there is still a small amount of water coming out of the battery casing and I’m concerned about its safety, so I haven’t yet put in on the charger.

Who is a “golf pro”?
why don’t you open, or make open, the battery case and dry it?

A golf pro is a golf professional, ie someone who teaches golf and sells golf apparel and equipment. I haven’t opened the battery, because it came with dire warnings about doing so.

What’s the different between a Nickel Metal Hydride, a Lithium Ion and a Manganese
Cobalt? Which one is the best?

What would be the capacity of Lithium Ion Battery for replacement of 12 volt 7 AH Lead acid battery for solar lantern of 5watt - 12 volt solar module ?

@Garrick: NiMH are older technology and heavier than lithium batteries.
“lithium ion” is generic for several technologies, including Manganese Cobalt, which are present in some recent lithium batteries, but I don’t know their performances.
Sometimes by “lithium ion” are referred first-generation lithium batteries (lot of energy, poor safety, Lithium-Cobalt based).
Manganese should allow better safety.

@Sanjeev:
At such low currents there’s no much difference between lead and lithium; lithium becomes better at high discharge rates, for example 7 A from a 7 Ah battery (=1C rate).
I don’t know the DIScharge rate of your lantern, but 5W/12V means just 0,42 A REcharge for a 7 Ah battery, which means 0.06C.

What you can do is replace the 12V/7Ah lead battery by a lithium battery with same capacity (7Ah) but 3 times lighter, or by a battery of same weight with 3 times the capacity.

In both cases, battery will last longer than lead battery.

Hi, I’ve been searching high and low just for some expert advice, and I’ve found your site care of another forum.  My question is that I play golf and my golf trolley is powered by a lead acid battery, which is about 5 years old now, and slowing down, I would like to get it replaced, but not sure whether to go for a lead acid one, or a lithium one, I’ve read at how lighter they are, but I need an experts reasoning, part from cost, why I would go for lithium over the lead acid.  Thank you very much in advance for your help.

I don’t think it is worth the effort of switching to lithium for a golf cart: main advantage of lithium is low weight, which allows better performance in acceleration and on slopes; it also allows wider range.
I don’t think a golf cart actually needs such improvements.
And a lithium battery costs 3 or 4 times a lead battery!
But if you want to experiment, look for TMF lead batteries or TPPL lead batteries: the first should be cheap and lightweight, the second expensive but they will last longer. But I don’t even know if they’re actually already commercially available.

Hi,  Many thanks for the quick reply…I never knew batteries could be so confusing.  I’ve taken your advice and have decided to go for lead.  I have checked, and as yet, TMF and TPPL are not available yet, but I’m bombarded with either VRLA, AGM or GEL batteries.  Seeing as I can’t get hold of a TMF or TPPL, should I just go for a standard lead acid ?  I was going to go for an AGM but have read that they are not as reliable.  Also, should I change my charger ?  I bought it from a golf retailer, and I really dont think it does the battery any favours.  Would I need a specific one depending on the battery I go for ?
Many thanks.

VRLA are not recommended for electric vechicles, they do not last long. Gel are fine for a golf cart, but I don’t know if you will have to change charger.

Thanks for all of your advice, greatly appreciated.

Just a note:  most of the comments above about the life of the battery has to do with useage, heat vs cold, etc. 

However, in a battery that is made up of more than one cell (depending on physical configuration), dropping the battery >> can << affect alignment and thus charging amounts.  An example of this occurs with some of the cheaper power supply backup units to provide power backups for your cell phone, music/video player,  laptop ‘puter, etc.
If you open the case, you might well find a whole bunch of “AA” battery cells, which are themselves built up of several button cell batteries (i.e. watch batteries) stacked together.  Obviously, dropping one of those units can quite easily result in a mechanical / physical displacement.  This would of course affect the charge storage capacity.

Are yoiu serious?!? How could displacement due to drop ever “change storage capacity”?? Battery will fail, or not; it will not “change”!

Yes, quite serious.  Fumble-fingered as I am, I have experienced the reduction of storage capacity, as in a quite noticeable reduction in usage time after charging subsequent to dropping the battery (usually though, after dropping more than once).  As to “how” it could happen instead of simply failing outright, I cannot say for certain since I did not autopsy the device.  I could offer some conjectures.  Depending on the type of battery, perhaps the ion matrix was disturbed (as in li-film?)  Or, as I suggested already, in the instance of multi-celled construction, with both serial and parallel units, if one of the units (or sub-units) became “displaced” the overall capacity would surely degrade, or even fail (of course), just like an analogous string of Christmas tree lights.  Again, speculatively speaking—since I haven’t opened up any dropped (degraded) units.

It’s more probable a damage to the INSIDE of a single cell rather than cells displacement: electrodes rupture?
Lithium batteries manuals suggest to trash batteries which got damaged when dropped (of course talking about big batteries, several Ah).

my mobile battery suddenly got bulged i dont wat to do and
y.Now i want to know y it got bulged and whether it will explode..
pls need reply..

What is it written on the battery label?

Anyway, keep it away from any wooden or plastic object (i.e., leave it on the floor away from furniture), as if it is NOT LiFePo4 based it CAN explode/burn!
(especially if LiPo based)

thanks Mr jumpjack ..actually it is 3.7vLi-ion battery..

yah my mom got scared n thrown into garbage…

Now it’s too late, anyway for the records: before throwing away a battery, don’t forget to put some duct tape over its terminal, to prevent short circuits in case it gets in touch with metal objects: both short circuit itself and high temperature reached by battery due to short circuit can cause a fire.

thanks Mr jumpjack for fast reply to my queries..

I got a lithium battery pack for my ski glove. On high it last for 2 hour, 4 hours for medium but on low it only last 3 hours. Why does the battery not working long on high? Does the cold weather affect the batteries from operating at its peaks power. Would it be better if I use some type of extra insulation around the battery pack so the battery would be cold.

All batteries (lead, lithium or whatelse) suffer in cold climate; they behave at best around 27°C, standard temperature at which they are tested (and labeled).
Bot charging and discharging them at low temperature reduce their capacity/duraton.

Can anyone tell me what the most efficient solar battery for so I can be removed off the power grid? and who manufactures it. I am having issues with the power companies about my solar rebate.

I think Thin Plates Pure Lead are the longer lasting. They cost more than classic lead batteries but less than lithium batteries.

I have two lithium ion batteries, each labeled 3.7 v, 6.4 Wh.  I charged both of them fully.  One now reads 3.99 volts, and runs my cell phone just fine.  The other reads 4.14 volts, and the cell phone does not operate with it.  What is happening?  Is this too much voltage?  Is there some sort of cutoff switch in either the phone or the battery if the voltage is too high?  Is there a safe way to lower the voltage, other than waiting for a very long time (It has been three weeks, and the 4.14 voltage has only dropped to 4.13 volts)?

I am an RC model airplane flyer, using all electric motors and Lipo batteries..
I have come across Li-ion batteries from a lap top computor and was wondering, if separated, can I use three for power on my motors??  12V or more??
The li-ion ones I have are CGR 18650 CE and eac h cell measures 4.14Volts now..
What is your comment on using this for my hobby??
Art.

Dear Art
lap top computor Li-ion batteries can not to discharge at high current…..but the RC model airplane need very high power , So DO NOT use this for your hobby, it is dangerous. you can buy the RC Lipo battery for your hobby

I have a samsung smxf44 camera which takes a lithium ion battery.  There are several
after market companies that offer batteries which are compatible.  Recently bought one that claims will replace my camera battery model IA-BP210E.  3.7V.  The battery is a Power 2000 professional digital battery.  It claims to be 2400MaH which may be higher than the original battery.  I understand this MaH has to do with how long the battery will keep a charge.  Am I correct?

There are several companies selling replacement batteries for Samsung.  I get no message on my camera that the battery is not compatible.

In any event, the battery will not fully charge or keep a charge and I am returning it.
Should I ask for a replacement or a refund? 

Last question.  Are lithium batteries dated so that I can tell whether I am getting an old or a new battery?

Thanks for any help you can provide.

in my view li-ion is best and cost effective.

I need that what is required to recharge the lithium iron battery?

which structure is convenient for running fruitful research in lithium ion battery?

dave is cool

There was a comment re Lithium not being the lightest metal and the comment mentioned Hdrogen is Atomic Mass 1 while Lithium is Atomic Mass 3 - Hydrogen however is not ametal so the text is correct Lithium is th elightest Alkali metal

I’d like to know if there are H emission during charging phase. In other words to charge electric vehicle is possible without any special requisition.
Many thanks for a your answer

li-polymer vs li-ion battery

Which one is best for the smart phone ( has a config 4G n/w, 2GHz processor, 2GB RAM, 13 MP cam)

I use Li ion battery in daily life.Which is the best.

These large 18 volt rechargeable batteries, in power tools, what is the cost to recharge them each time. I read that a mobile phone battery, charged every day, would be around ten cents for the whole year. How do these huge heavy batteries compare?

I’m replacing a 7.2v Varta 250mAh NiMH backup battery pack from an appliance that has an 8.4v constant charge. I was intending to replace the battery with 2pc of ICR14500 (7.2v) with protection chip built in.

My question is, regardless of performance, life, suitability, etc. Will the ICR battery explode or just fail?

I use a Turnigy 5000mAmAh 4s1P 14.8v 20C hardcase pack in my ultralight.  After leaving it in the plane for a month or so, with temps in the teens and twenties, I got only a series of clicks when I tried to start the plane.  I removed the battery and charged it in my balance charger to full capacity.  The plane will now start.  Do you think the freezing weather harmed the battery in the long run or will it take several of these freezing episodes to damage it?  Probably I should take it out of the plane if freezing temperatures are expected.  What do you think?

I have Li-ion battery in my mobile and a power bank which is Li-poly battery. Can I use that power bank to charge my mobile

Hello all- My “out in the woods” surveillance camera uses 8 AA batteries. In eastern PA, with use from April to October (staying always outdoors), low temp can be expected around 0 F., and it is late at night that I would expect the camera to be tripped (if at all). It is not very active as it is surveillance. I don’t want to buy more than one set of batteries per season (is that possible?) and I don’t want to spend any more than necessary. I can go rechargeable or disposable. So, for examples- alkaline is bad in the cold, lithium is expensive, lithium-ions recharge unevenly, etc.
  What should I buy?

Oops, I mean (above) freezing, not 0.

I have some informatio about:
” Various additives for applicable electrolytes at the lithium-ion batteries “
Thank you for your attention.

My employer just invested in a new universal remote that has a lithium ion battery in it.  It is replacing another remote that also used a lithium ion battery.  The battery on the old remote didn’t seem to last longer than a year.  I live on an island that is very humid and surrounded by the ocean, it doesn’t sound like it is worth keeping an extra battery around, should the current one start to fail.  I need to make sure that remote is always operational.  Any suggestions?

What is the difference between the carbon electrode used in Li ion batteries and a normal Leclanche cell?

I have read through the thread and have not seen this question.
I am running a survey robotic total station using Li-ion batteries and looking for compatible replacements/extras.  What are the differences in batteries marked Li-ion20 and Li-ion00 or batteries just marked Li-ion?  Should they be compatible?
Thanks for any explanations.

On purchase of a new 3.7v volt rechargable (mob ph) lithium battery some suppliers advise to full charge 4 times before use (8 hour charge period), others make no mention of this.What is accepted initialising and discharge current of a new battery before use please

What batteries would serve best in portable solar kits. Kits that use a 10 watt panel, 10 amp charge controller and a 100 watt inverter! Currently using 2,  10 amp hour acid sealed batteries which provide 6 hours of KED light via 3, 5 watt bulbs and a 2.5 watt LED fan. Thanks

Thanks.

I was using Cu foil for Lithium titanium oxide electrode coating. However, the Cu foil is interfering with my energy spectra. Is there any other alternatives to avoid this problem?

Thanks in advance.

Why would a lithium ion handheld radio battery in place in a charger explode producing what appears a lot of explosive energy what has failed? Temperature circuitry? Why so powerful?

is their potential to go for manufacturing in india Li-ion battary in rurar area.

just make it like a Sandwhich.

thanks for da infomation

Where can I find a reference for a typical battery construction with all detailes?

your site is informative

What should I do when the battery fallout of my phone?
Should I put it back ?

If a Li-ion battery has been put on a NiCd charger and run will the battery be any good if put on the correct charger or will it be stuffed.
Thanks

The global lithium production is composed for sustained growth in the years ahead. Polymers followed by li-ion batteries application are expected to be the largest contributor to the future growth in the global lithium market through 2020. Between 2015 and 2020, the overall lithium consumption will likely post 11.93% YoY growth in terms of volume. Chile and Australia are the largest producers of lithium followed by China, Argentina, Zimbabwe and U.S.A among others.

The comment about a liquid battery. Liquid is heavy, 10+
pounds per gallon, that’s why such a push for dry cells, plus the mess of liquid. When you put 10 gallons of gas in your car, you are also adding about 100 lbs. There are cell phones now with a type-c usb rapid charge system, 15 minutes can give up to 10 hours of use. When a car battery system can produce these type of results it will happen, but for now the logistics of an electrical vehicle is far off.

I have a lithium ion battery pack (18650) five battery’s. When placed in my edger or blower these units will run for a short period of time then slow down and stop. If I wait for two minutes the units come on strong and again after a short period of time they slow and stop. Checking the voltage it back at 19 volts is there a problem with the battery breaking down internal then repairing it self or something in the protecting circuit.

Yes I need hands on fancy Li battery for personal use against enemies. I hold very low monetary value of US dollar, but no problem because I will pay you back once I cause country to fall. I offer $34 for battery to allow charger of atom splitter in new device.I willing to negotiate, yes? Please use email if interest is drawn.

I replaced all of my wall clock batteries with AA Li-ion batteries two months ago, but after learning that they have a higher voltage than standard alkaline batteries, I am wondering whether this was a wise choice. The clocks are working fine but is the higher voltage likely to shorten their life?
Also, is it possible to replace garden solar lights with rechargeable Li-ion batteries or will they damage the LEDs?
Grateful for any advice on these.

nice to read those first comments after 6yrs. nice also to notice how li-po’s are improved during the time.

Has anyone found another source to purchase replacement Li-lon batteries for a Inogen One oxygen concentrator or a charger? 

Thanks for all help

Can the same charger be used for a Li-ion and a Li-ion polymer battery?
Thank you

Could a lith-ion battery be used on solar gokart?
