Three-dimensional graphene powder high specific capacity lithium battery anode material (G02)

Made by growing vertical graphene on the surface of natural graphite particles, this three-dimensional graphene powder has outstanding lithium storage performance, the specific capacity is much higher than the theoretical capacity of graphite, and the rate performance is particularly outstanding. It is an excellent high-capacity fast-charging negative electrode Material. At a current density of 0.2C, the specific capacity was as high as 516mAh/g after 100 cycles, and the capacity remained 105mAh/g after 3000 cycles at a current density of 5C. The energy density of the full battery is as high as 434Wh/kg at 0.1C, and the energy density of 300Wh/kg can be obtained by charging at a rate of 4C for 10 minutes. It is a new type of anode material with good application prospects.
