Currently,NEV manufacturers use artificial graphiteas anode material for lithium battery.However,per-gram capacity of graphite anode material has climbed to the ceiling,i.e.372 m Ah/g.The battery energy density can hardly exceed 290 Wh/kg in spite of the collocation with high nickel cathode material(NCM8),which means it fails to meet the energy density goal of 300-350 Wh/kg set by our country.
