 Products Description 

Flake graphite belongs to natural graphite and is obtained by purifying mined natural graphite. It is mainly used in the preparation of graphite anode, graphene, expanded graphite, and lubricants; it cannot be directly used as a negative electrode material for lithium-ion batteries.

Hard carbon capacity testing process suggestion: Rest 4h, 0.2C DC to 0V, 0.1C DC to 0V, 0.01C DC to 0V, 10μA DC to 0V, rest 3 min, 0.1C CC to 2V.
