Graphite is the largest material component of EV batteries. The typical EV battery has somewhere between 50-100 kilograms of graphite. Graphite forms almost the entire anode side of the battery with silicon often being used as an additive at roughly 5% of the anode. The rest of the anode is all graphite.
Lithium-ion batteries with lithium cobalt oxide (LiCoO2) as a cathode and graphite as an anode are promising energy storage systems. However, the high-temperature storage mechanism under different states of charge (SOCs) conditions in batteries remains inadequately elucidated, and a clear storage policy has yet to
