Demand for the metal, which is critical to EV batteries, could soon outstrip supply
An electric car future is speeding closer; economic analysts project that a third of all automobiles could be battery-powered by 2040. Most of these vehicles rely on large lithium-ion batteries, prompting worries about whether the world’s lithium supply can keep up.
But another element—cobalt—is a bigger concern, scientists reported in October in the journal Joule.
“The best lithium battery cathodes [negative electrodes] all contain cobalt, and its production is limited,” says study lead Elsa Olivetti, a materials scientist and engineer at the Massachusetts Institute of Technology.
