What is the capacity principle of graphite?
The capacity principle of graphite is because graphite has a layered structure suitable for lithium ion intercalation and deintercalation. Graphite has the advantages of low cost, abundant reserves, low voltage platform and small volume change during intercalation and deintercalation, and is an ideal anode material for lithium ion batteries. Graphite material is the mainstream of anode market at present. The specific capacity of market-oriented graphite anode is above 330mAh/g, and the first Coulomb efficiency is above 90%.
