Availability of Lithium

The demand for Li-ion batteries is increasing, and finding sufficient supply of lithium as a raw material is testing the mining industry. A compact EV battery (Nissan Leaf) uses about 4kg (9 lb) of lithium. If every man, woman and teenager were to drive an electric car in the future, a lithium shortage could develop and rumor of this happening is already spreading.

About 70 percent of the world’s lithium comes from brine (salt lakes); the remainder is derived from hard rock. Research institutes are developing technology to draw lithium from seawater. China is the largest consumer of lithium. The Chinese believe that future cars will run on Li-ion batteries and an unbridled supply of lithium is important to them.

In 2009, total demand for lithium reached almost 92,000 metric tons, of which batteries consume 26 percent. Figure 1 illustrates typical uses of lithium, which include lubricants, glass, ceramics, pharmaceuticals and refrigeration.

Batteries consume the largest share of lithium, and with the advent of the electric vehicle the demand could skyrocket. For now, the world has enough proven lithium reserves.

Most of the known supply of lithium is in Bolivia, Argentina, Chile, Australia and China. The supply is ample and concerns of global shortages are speculative, at least for the moment. It takes 750 tons of brine, the base of lithium, and 24 months of preparation to get one ton of lithium in Latin America. Lithium can also be recycled an unlimited number of times, and 20 tons of spent Li-ion batteries yield one ton of lithium. This will help the supply, but recycling can be more expensive than harvesting new supply through mining.

Named after the Greek word “lithos” meaning “stone,” lithium is inexpensive. The raw material costs a fraction of one cent per watt, or less than 0.1 percent of the battery cost. A $10,000 battery for a plug-in hybrid contains less than $100 worth of lithium. Shortages when producing millions of large batteries for vehicles and stationary applications may increase the price. Cobalt, another component found in some Li-ion batteries, is expensive and if required in high volume, demand for this hard and lustrous gray metal could cause global shortages.

At the time of writing, there are no other materials that could replace lithium, nor are battery systems in development that offer the same or better performance as lithium-ion at a comparable price. Rather than worrying about a lack of lithium, graphite, the anode material, could also be in short supply. A large EV battery uses about 25kg (55lb) of anode material. The process to make anode-grade graphite with 99.99 percent purity is expensive and produces much waste.

There is also a concern about pending shortages of rare earth materials for permanent magnets. Electric motors with permanent magnets are among the most energy efficient, and these are finding their way into EV powertrains. China controls about 95 percent of the global market for rare earth metals and expects to use most of these resources for its own production.

We should make the extraction of these rare minerals a priority. 

Forget going to Mars.  We need to set goals and do them.  Unmanned and just for telecommunication should be our only concern with space.

China has set a goal to do it.  We should also be careful to protect our processes since The Energy Department had Chinese spies in the past.  Johnson Controls (a process computer corporation) is building a battery plant in China and here.  This is a situation where they let us build their plant and then copy it. We have been sloppy protecting industrial secrets in the past with corporate CEOs getting pay offs to giving it away. That is bad economic policy.

J. Stevens, the situation is as following:

Rare-earth minerals, are as the name suggests, rare. So rare that the earthian deposits of these minerals cannot keep up with the demand, and can run out within several decades. Going to other planets is one way to keep a steady supply, as planets like mars are likely to contain all sorts of minerals. Harvesting asteroids is also a way to obtain raw materials, an avarage asteroid can contain more iron than the human race has ever used.
So may asteroids contain insane amounts of rare-earth minerals, like lithium or cobalt.
Thus space exploration and exploitation would be an essential way to keep up with the global demand for raw materials.

Then there is also the need for the famed helium-3 isotope, practically non-existant on earth, this rare gas is valued for its potential in nuclear-fusion; a process where 2 atoms are fused to create 1 larger atom, which releases massive amounts of heat, like stars do. This heat can be used to generate electricity very cleanly and efficiently.
The only way to obtain helium-3 in sufficient amounts would be space-exploration and exploitation, as our gas giants contain massive amounts of this gas, enough to be easely harvested using balloons and use some of the gas as fuel for a return flight to earth.

In the end space exploration will benefit us more on the long run, as it will allow us to set up permanent bases on other planets which we could expand for mining- and harvesting operations. And with our rapidly advancing technology this would be even more feasable as a functional space-evelator, would be just a decade or 2 away.

The Battery University is one up on Wikipedia on Lithium Batteries between the two information sources I have me totally consumed even in my sleep (its fun to get excited and learning something so important). I hope to find a niche in the technology. I wanted to say thank you for the knowledge! BB (retired)

James Elwood Swenor, being Canadian and using Apple products won’t make a bit of difference. You will still be subject to China for your technology. You are aware that China is where Apple makes its products, aren’t you? So what you said is irrelevant to the subject of this article. Canada has less known lithium than the United States and an increasing need.

The environment impact of electric car is yet another big hoax being spread in the world. The key is to reduce activity. Obviously, billions of people can’t drive electric cars, as tehreis not enough material on this planet to build those.
  The key to saving the planet is to drive smaller cars, drive less. Encourage work-from-home to reduce commute needs and traffi cjams, so even fewer roads need to be built. These are real earth savers.
