Grade is important in certain areas but the term, “battery grade” is a marketing term over used by junior minors and analysts that don’t really understand the industry. Batteries going into Tesla’s cars are not made with, “battery grade” material as originally defined by their largest lithium supplier. There are certain specifications that lithium raw material must have, but, “battery grade” as a generic term creates more confusion than anything else. The, “premium” many analysts discuss for, “battery grade” lithium carbonate is largely a myth.
