The lithium-ion (Li-ion) batteries that power most evs are their single most-expensive component, typically representing some 40% of the price of the vehicle when new. The materials these batteries are made from define its performance, hence they help determine how far an ev can travel on a single charge, how fast it can go and how long its battery will last. In turn, the most critical component in those batteries are its cathodes, accounting for around half their value. Do you thik that the world will go compleltely electric?
