Electric vehicles will play an important role in reducing greenhouse gas emissions, but they are not yet a perfect solution. Today, most EVs run on lithium-ion batteries made with heavy metals like cobalt, of which there is a limited supply and less than ideal mining conditions. The IBM Research Battery Lab may have a solution: a new battery built without heavy metals. It’s made, instead, with materials that can be extracted from seawater.
