▎ 摘　　要

NOVELTY - The material has a silicon-based anode material structure including nano-silicon particles and a graphene multiple coating layer covering the nano-silicon particles. The graphene multiple coating layer is composed of an inner layer containing reduced graphene oxide and an outer layer containing liquid-phase exfoliated graphene, where grain diameter of the reduced graphene oxide is greater than 1 micro meter. USE - Silicon-based negative electrode material. ADVANTAGE - The material improves conductivity and mechanical performance of the system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a Silicon-based negative electrode material.
