Cobalt is a metal that few investors know much about – it is critical to the electric vehicle (EV) revolution because it makes up some 35% of the lithium-ion battery mix. That’s 30% of batteries that are the backbone of EVs, EVs that are now mainstream. To meet demand for EVs, billion-dollar battery gigafactories have been built and continue to be built. Consumer electronics are contributing to the demand and resulting shortage of supply.
