▎ 摘　　要

NOVELTY - Hybrid graphene composite particles comprise a graphene composite comprising a mixed structure of several primary microparticles and multilayer graphene and secondary microparticles surrounded by the graphene composite. Graphene is coated on the surface of the primary or secondary microparticles. The primary microparticles are bound to the surface or inside of the multilayer graphene, and a portion of the empty space between the primary microparticles is filled with the graphene to form an interconnected structure. USE - Hybrid graphene composite particles used for negative electrode or positive electrode for lithium-ion battery for portable mobile devices such as smart phones and netbooks. ADVANTAGE - The hybrid graphene composite particles form a stable graphene composite structure, significantly improve charge/discharge speed and efficiency with high electroconductivity, and maximize the capacity that lithium ions can combine to realize lithium-ion battery with both performance and stability.
