Nickel and cobalt have precarious international supply chains, but eliminating them from batteries raises tough questions.
The electric vehicle or EV revolution owes its existence to lithium batteries, and those batteries have a cocktail of specialized minerals to thank for their high performance.
In most cases, that cocktail’s ingredient list includes cobalt and nickel, minerals that help deliver the long lifespan and range that consumers increasingly demand of EVs.
But with hundreds of millions of new EVs expected to hit the streets in the coming decades, skyrocketing demand for nickel and cobalt could strain mineral supply chains. Fearing a supply shortage that would slow the EV boom, the U.S. Department of Energy is now proposing that we eliminate cobalt and nickel from batteries altogether.
