Mines extract raw materials; for batteries, these raw materials typically contain lithium, cobalt, manganese, nickel, and graphite. The "upstream" portion of the EV battery supply chain, which refers to the extraction of the minerals needed to build batteries, has garnered considerable attention, and for good reason.. Many worry that we won''t extract these minerals
