Speculation arose that graphite could be in short supply because a large EV battery requires about 25kg (55 lb) of graphite for the Liion anode. Although price and consumption has been lackluster, there are indications that the demand is tightening. Producing anodegrade graphite with 99.99 percent purity is expensive and the process createsThe History of Graphite Empowering Pumps and ,The History of Graphite. In fact, all the chemicals added to the flake to promote expansion are removed during this hightemperature process.
