BU-705: How to Recycle Batteries

Learn about disposal and how toxic material can continue to be used in batteries if recycled.

Lead- and cadmium-based batteries pose the largest environmental concerns, so much so that nickel-cadmium was banned in Europe in 2009. Attempts are being made to also ban the lead-based battery, but no suitable replacement is available as was the case by substituting nickel-cadmium with nickel-metal-hydride. For the first time, lithium-ion has been added to the list of pollutants. This chemistry was classified as only mildly toxic, but their sheer volume requires tighter scrutiny.

Lead acid paved the way to the success of recycling, and today more than 97 percent of these batteries are recycled in the USA. The automotive industry should be given credit for having organized recycling early; however, business reasons rather than environmental concerns may have been the driving force. The recycling process is simple and 70 percent of the battery’s weight is reusable lead.

Over 50 percent of the lead supply comes from recycled batteries. Other battery types are not as economical to recycle and are not being returned as readily as lead acid. Several organizations are working on programs to make the collection of all batteries convenient. Only 20 to 40 percent of batteries in mobile phones and other consumer products are currently recycled. The goal of recycling is to prevent hazardous materials from entering landfills and to utilize the retrieved materials in the fabrication of new products.

Spent batteries should be removed from the household. Old primary cells are known to leak and cause damage to the surrounding area. Do not store old lead acid batteries where children play. Simply touching the lead poles can be harmful. Also, keep button cells hidden from small children as they can swallow these batteries. ( See BU-703Health Concerns with Batteries )

Even though environmentally unfriendly, lead acid batteries continue to hold a strong market niche, especially as a starter battery. Wheeled mobility and UPS systems could not run as economically if it were not for this reliable battery. NiCd also continues to hold a critical position among rechargeable batteries as large flooded NiCds start jet airplanes and propel sightseeing boats in rivers of larger cities. Although pollution-free, these batteries are in decline.

Batteries with toxic substances will continue to be with us and there is nothing wrong in using them as long as they are being disposed of properly. Each battery chemistry has its own recycling procedure and the process begins by sorting the batteries into the correct categories.

Lead Acid: Recycling of lead acid began with the introduction of the starter battery in 1912.  The process is simple and cost-effective as lead is easy to extract and can be reused multiple times. This led to many profitable businesses and the recycling of other batteries.

In late 2013, smelters started to report an increased number of Li-ion batteries being mixed in with lead acid, especially in starter batteries. This can cause fires, leading to explosion and personal injury. The physical appearance of lead acid and Li-ion packs are similar and sorting at high volume poses a challenge. For consumers, a battery is a battery and folks are enticed to recycle all batteries, never mind the chemistry. As more lead acid are being replaced with Li-ion, the problem will only escalate. From 2010–2013, there has been a 10-fold increase in reported incidents of infiltration of Li-ion with lead acid.

Please note that Li-ion is more volatile when stripped than lead acid. Presorting is done for safety reasons and not to separate hazardous material. Lead acid is benign but toxic, Li-ion is non-malignant but explosive.

The Society of Automotive Engineers (SAE) and the International Electrotechnical Commission (IEC) initiate action through increased awareness, employee training, battery identification and labeling. X-ray technologies to separate batteries are being explored and “who carries the liability?” is being asked. Battery manufacturers put the responsibility on the recyclers who in turn argue that the burden and sustainability of a product must be borne by the manufacturer. The courts may become the arbitrators.

Nickel-cadmium: When NiCd batteries are disposed of carelessly, the metallic cell cylinder eventually corrode in the landfill. Cadmium dissolves and seeps into the water supply. Once contamination begins, authorities are helpless to stop the carnage. Our oceans already show traces of cadmium (along with aspirin, penicillin and antidepressants) but scientists are not certain of its origin.

Nickel-metal-hydride: Nickel and the electrolyte in NiMH are semi-toxic. If no disposal service is available in an area, individual NiMH batteries can be discarded with other household waste in small quantities; however, with 10 or more batteries, the user should consider disposal them in a secure waste landfill. The better alternative is taking the spent batteries to a neighborhood drop-off bin for recycling.

Primary Lithium: These batteries contain metallic lithium that reacts violently when in contact with moisture and must be disposed of appropriately. If thrown in a landfill in a charged state, heavy equipment operating on top could crush the cases and the exposed lithium could ignite a fire. Landfill fires are difficult to extinguish and can burn for years underground. Before recycling, apply a full discharge to consume the lithium content. Primary lithium batteries (lithium-metal) are used in military combat, as well as in watches, sensors, hearing aids and memory backup. A lithium-metal variety also serves as alkaline replacement in AAA, AA and 9V formats. Li-ion for mobile phones and laptops do not contain metallic lithium. ( See also BU-106: Advantages of Primary Batteries )

Lithium-ion: Li-ion is reasonably harmless but spent packs should be disposed of properly. This is done less to retrieve valuable metals, as is the case with lead acid, than for environmental reasons, especially with the growing volume used in consumer products. Li-ion contains harmful elements that are at the toxicity level of electronic devices.

With the increasing use of Li-ion, the European Commission report named “Towards the Battery of the future” delivers warnings because of the large number of batteries that will meet end-of-life. In Europe, Li-ion cannot be landfilled because of toxicity and danger of explosion, nor can they be incinerated as the ashes are also toxic in landfill. Of concern is cobalt and agents that bind electrode materials together.

The report no longer brands lead acid as the most toxic battery. Lead acid is the only battery that can be recycled profitably. With almost 100% of lead acid being recycled, the focus with spent batteries shifts to Li-ion because of high volume.

Alkaline: After lowering the mercury content in alkaline batteries in 1996, many territories now allow disposing these batteries as regular domestic trash; however, California considers all batteries hazardous waste. In Europe, lead acid, NiCd, mercury containing batteries, unsorted collections of multiple battery types, and battery electrolytes are considered hazardous waste. All others can pass as non-hazardous. Most stores selling batteries are also required to take back spent batteries. Alkaline batteries contain the reusable materials of zinc and manganese but the retrieval process is a liability. Efforts are made to increase the recycling of alkaline cells from the low 4 percent in 2015 to 40 percent in 2025.

In North America, Retriev Technologies, formerly Toxco, and the Rechargeable Battery Recycling Corporation (RBRC) collect spent batteries and recycle them. While Retriev has its own recycling facilities, RBRC is in charge of collecting batteries and sending them to recycling organizations. Retriev in Trail, British Columbia, claims to be the only company in the world that recycles large lithium batteries. They receive spent batteries from oil drilling in Nigeria, Indonesia and other places. They also recycle retired lithium batteries from the Minuteman missile silos and tons of Li-ion from war efforts. Other divisions at Retriev recycle nickel-cadmium, nickel-metal-hydride, lead, mercury, alkaline and more.

Europe and Asia are also active in recycling spent batteries. Among other recycling companies, Sony and Sumitomo Metal in Japan and Umicore in Belgium have developed technology to retrieve cobalt and other precious metals from spent lithium ion batteries. ( See BU-705a: Battery Recycling as a Business )

Umicore uses an ultra-high temperature (UHT) processes to recycle Li-ion and NiMH batteries. Spent packs are dismantled and melted in an UHT furnace. The derbies are separated into metal alloy containing copper, cobalt and nickel, and slag, a stony waste containing rare earth metals. Slag can be further processed to recover lithium, but producing battery-grade lithium is not yet economical and the slag is used for construction. Methods are being developed to extract lithium for reprocessing into lithium carbonate for Li-ion production. With an anticipated 10-fold growth in the use of Li-ion batteries between 2020 and 2030, the reuse of lithium could become economical so the metals end up in battery production again much like lead for lead acid batteries.

Recycling Process

Recycling starts by sorting batteries into chemistries. Collection centers place lead acid, nickel-cadmium, nickel-metal-hydride and lithium ion into designated drums, sacks or boxes. Battery recyclers claim that recycling can be made profitable if a steady stream of batteries, sorted by chemistry, is made available.

The recycling process begins by removing the combustible material, such as plastics and insulation, with a gas-fired thermal oxidizer. Polluting particles created by the burning process are eliminated by the plant’s scrubber before release into the atmosphere. This leaves the clean and naked cells with metal content.

The cells are then chopped into small pieces and heated until the metal liquefies. Non-metallic substances are burned off, leaving a black slag on top that a slag arm removes. The alloys settle according to weight and are skimmed off like cream from raw milk while still in liquid form.

Cadmium is relatively light and vaporizes at high temperatures. In a process that appears like a pan of water boiling over, a fan blows the cadmium vapor into a large tube that is cooled with water mist. The vapors condense to produce cadmium that is 99.95 percent pure.

Some recyclers do not separate the metals on site but pour the liquid metals directly into what the industry refers to as “pigs” (65 pounds, 24kg) or “hogs” (2,000 pounds, 746kg). Other battery recyclers use nuggets (7 pound, 3.17kg). The pigs, hogs and nuggets are shipped to metal recovery plants where they are used to produce nickel, chromium and iron for stainless steel and other high-end products.

To reduce the possibility of a reactive event during crushing, some recyclers use a liquid solution or freeze lithium-based batteries with liquid nitrogen; however, mixing Li-ion starter batteries with the common lead acid type still remains a problem as a charged Li-ion is far more explosive than lead acid.

Battery recycling is energy intensive. Reports reveal that it takes 6 to 10 times more energy to reclaim metals from some recycled batteries than from mining. The exception is the lead acid battery, from which lead can be extracted easily and reused without elaborate processes. To some extent, nickel from NiMH can also be recovered economically if available in large quantities.

New recycling methods are being developed that retrieve the metals by electrolysis, also knowns as chemical recycling. The process is said to be more cost effective and produces higher yields with less pollutants than traditional smelting. One such alternative to recycle lead acid batteries has been developed by Aqua Metals. This technology has the potential of revolutionizing traditional melting methods. An electrochemical process separates the lead by breaking down metals into nanoscopic sizes particles that are dispersed in water to create a hydro-collodial metal. The process is called AquaRefining. Technical issues are delaying full implementation at this time.

Each country sets its own rules and adds tariffs to the purchase price of a new battery to make recycling feasible. In North America, some recycling plants invoice by weight and the rates vary according to chemistry. While NiMH yields a fairly good return with nickel, the spent NiCd battery is less in demand because of soft cadmium prices. Due to poor metal retrieval value, Li-ion commands a higher recycling fee than most other battery types.

Recycling Li-ion batteries is not yet profitable must be government subsidized. There is an incentive to recover costly cobalt. No recycling technology exists today that is capable of producing pure enough lithium for a second use in batteries. Lithium for batteries is mined; second hand lithium is used for lubricants, glass, ceramics and other applications.

The flat cost to recycle a ton of batteries is $1,000 to $2,000; Europe hopes to achieve a cost per ton of $300. Ideally, this would include transportation, but moving and handling the goods is expected to double the overall cost. To simplify transportation, Europe is setting up several smaller processing plants in strategic geographic locations. This, in part, is due to the Basel Convention that prohibits the export of complete but spent lead acid batteries. As the volume of discarded batteries increases, new technologies are being tried to make recycling profitable without the support of agencies and governments.

Caution: Under no circumstances should batteries be incinerated, as fire can cause an explosion. Wear approved gloves when touching the electrolyte. On exposure to skin, flush with water immediately. If eye exposure occurs, flush with water for 15 minutes and consult a physician immediately.

The problem begins by sorting the batteries into chemistries. Why? ... There is many types and battery kinds. It’s impossible of perfectly sorting by quality. For the present, the recognized “qualities” are dispatched to specialized recycling centers having their own technology. A very large part of batteries are not recycled - for their elements- because of it’s impossible to sort them. Other problem: the recycled metals are often not enough pure to be reused by industrie. That is like sugar and salt mixed: not good for soup or cake!
“To simplify transportation, Europe is setting up several smaller processing plants…” In fact, the batteries from collection centers are transported to sorting centers and are transported again to recycling centers according to their kinds; each recycling center must re-sorting the material before treatment and in all case, a part return to the sorting centers, etc.
With a new technology able to recycle both all battery types with a good efficiency and 99.99 by metals and elements production, the transportation and the recycling costs will be largely reduced.

Hi - great article and comments!
I wonder if anyone knew any info on the difference between “recycling” and “closed loop” in terms of battery price.

I know that lead-acid is essentially closed loop. Generally the highest quality batteries use the bulk of virgin lead and the huge mass of starter batteries which have far lower requirements use up much of the recycled lead. True closed-loop manufacture is profitable in lead-acid batteries.

But with lithium I have heard that a true closed-loop system (in the way lead-acid is largely closed loop) where the battery material is in no way profitable and in fact would push the cost of the cells way up if implemented. This is particularly true once expensive cobalt is less frequently used in li-ion batteries.

So if li-ion batteries had to be broken down and remade as new li-ion batteries, what would be the cost of the recycled cell? Anyone seen such info anywhere?

First of all, Mr. Modi should be very proud, because Indians are taking the “Bulll by the horns” and trying to make a business of batt-ry recycling. It is just another form of the scrap metal business. What amazed me is this thread is 5 years old, yet it is still active! This is a good example of a thing our governments could do more than just regulate. I believe webwill all be digging through our landfills, and expending great energy to recover metals, in my lifetime,

With finite, but huge, lithium resources, and the very small lithium content of GP batteries, it appears hardly worth recycling them. However the advent of PV cars, lorries etc will only increase the use of these resources. Please remember that these large lithium resources are irreplaceable, and when, like oil, they are exhausted we have two problems.  Firstly the pollution from disposed batteries and second, the replacement technology.
Do we want a nuclear car pile? - leading to a nuclear car pileup- oops.
Lets recycle, effectivly, what we have left of this planets resources rather than squandering them

This will allow the planet to recycle efficiently, leaving its resources abandoned

Hi everybody
I’m working on recycling lead-acid batteries (car batteries)
And acutely I have several ideas for making some changes in some recycling processes ... and i need your suggestions
On of my new ideas is to reduce the energy and cost and even time and workman .... as known. . To produce lead oxide : at first you have to convert the old paste (lead oxide ) to pure lead metal and then refine it ,then insert it to the ball mill ,, so what if we use anther way instead of that:
Can I recycling the old lead doxide to new lead oxide by this process :
At first
I have a proposal to produce the oxide

it’s known that to get new oxide —-> the old oxide is melted—-> get the lead
—-> and then it is grinded by a ball mill —-> we get a new oxide.
It can be another way to get new oxide
for example:
We want to get a new oxide which is scientifically called lead oxide pbo
Which is yellow

Ok, you know that the old paste in the positive panels of the battery is a lead dioxide pbo2 and dark brown

When the old dioxide (pb2) is exposed to a temperature of up to 600 ° C in air , it turns (reduce) to the first lead oxide (pbo) and we can recognize it by it’s color , which is the oxide that we want to form the paste on the lead grids

For Suggestions

I just got Panasonic eneloops (AAAs) and an OPUS BT-C2000 charger. I chose them largely on the recommendations of “NLee the engineer” on Amazon. Afterward I found Battery University and CandlePowerForums. The batteries charge up nicely and the OPUS has lots of nifty features. One oddity though: Neither the OPUS charger box nor the instruction leaflet lists a corporate address. The charger label says “Made in China,” but that’s it. No corporate address. No website or phone number, either.

Thank you for providing such a valuable information, I was wondering this communication started in 2011 with some appreciation and still going on with companies seeking batteries earn some money.

Guys please love nature not the increasing numbers in your bank account….. 100% of rich people do not even use 1% of their total property but still we are running like a blind hog behind this money…..

we are running towards our doom…

This article states, “Reports reveal that it takes 6 to 10 times more energy to reclaim metals from some recycled batteries than from mining. “

Could you cite the specific reports? I have been trying to find studies that calculate the energy costs of recycling alkaline batteries in particular.

And what about to pour out the acid before melting batteries? I have heard that some companies throw batteries out of a big crane to the pit where the acid leak out and it is then caught and reprocessed. Until that step the batteries can be crashed and so the lead, plastic etc parts can be separated and also reprocessed. This way it can be also acid reprocessed again.
But still very interesting job smile
