I have spent the last year working on a book called Fight the Fire: Green New Deals and Global Climate Jobs. Most of it is about both the politics and the engineering of any possible transition that can avert catastrophic climate breakdown. One thing I had to think about long and hard was lithium and car batteries.
I often hear people say that we can’t cover the world with electric vehicles, because there simply is not enough lithium for batteries. In any case, they add, lithium production is toxic, and the only supplies are in the Global South. Moreover, so the story goes, there are not enough rare earth metals for wind turbines and all the other hardware we will need for renewable energy.
People often smile after they say those things, which is hard for me to understand, because it means eight billion people will go to hell.
So I went and found out about lithium batteries and the uses of rare earth. What I found out is that the transition will be possible, but neither the politics nor the engineering is simple. This article explains why. I start by describing the situation simply, and then add in some of the complexity.
Lithium is a metal used in almost all electric vehicle batteries today. About half of global production of lithium currently goes to electric vehicles. And in future we will need to increase the production of electric vehicles from hundreds or thousands to hundreds of millions. That will require vast amounts of lithium.
There are three ways to mine lithium. It can be extracted from rock. It can be extracted from the brine that is left over when sea water passes through a desalination plant. Or it can be extracted from those brine deposits which are particularly rich in lithium. These brine deposits are the common way of mining lithium currently, because it is by far the cheapest. Most of the known deposits of lithium rich brine are in the arid highlands where Bolivia, Chile and Argentina come together.
Lithium mining is well established in Chile and Argentina. In both countries the local indigenous people have organized against the mining, but so far been unable to stop it. The mining is toxic, because large amounts of acid are used in the processing. But the mining also uses large amounts of water in places that already has little enough moisture. The result is that ancestral homelands become unlivable.
Bolivia may have even richer deposits of lithium than Argentina and Chile, but mining has not begun there. The Bolivian government had been led by the indigenous socialist Evo Morales from 2006 to 2019. Morales had been propelled to power by a mass movement committed to taking back control of Bolivia’s water, gas and oil resources from multinational corporations. Morales was unable to nationalize the corporations, but he did insist on the government getting a much larger share of the oil and gas revenue.[1]
His government planned to go even further with lithium. Morales wanted to mine the lithium in Bolivia, but he wanted to build factories alongside the mines to make batteries. In a world increasingly hungry for batteries, that could have turned Bolivia into an industrial nation, not just a place to exploit resources.
The Morales government, however, was unable to raise the necessary investment funds. Global capital, Tesla, the big banks and the World Bank had no intention of supporting such a project. And if they had, they would not have done so in conjunction with a socialist like Morales. Then, in 2019, a coup led by Bolivian capitalists, and supported by the United States, removed Morales. Widespread popular unrest forced a new election in October. Morales’ party, the Movement for Socialism won, though Morales himself was out of the running. It is unclear what will happen to the lithium.
That’s one level of complexity. The local indigenous people did not want the lithium mined. The socialist government did not want extractavism, but they did want industrial development.
Those are not the only choices.
For one thing, there are other, more expensive ways of mining lithium. It can be mined from hard rock in China or the United States. More important, batteries do not have to be made out of lithium. Cars had used batteries for almost a century before Sony developed a commercial lithium-ion battery in 1991. Engineers in many universities are experimenting with a range of other materials for building batteries. But even without looking to the future, it would be possible to build batteries in the ways they used to be built. Indeed, in January 2020, the US Geological Service listed the metals that could be substituted for lithium in battery anodes as calcium, magnesium, mercury and zinc.[2]
The reason all manufacturers currently use lithium is that it provides a lighter battery that lasts longer. That gives the car greater range without recharging, and it make possible a much lighter car. In other words, lithium batteries are cheaper.
