▎ 摘　　要

NOVELTY - Preparation of graphene and graphite composite material comprises subjecting graphite with hydrolysate to surface treatment to obtain surface-treated graphite, adding graphene dispersion, and carbonizing. USE - The method is for preparation of graphene and graphite composite material used as negative electrode material of lithium ion battery (claimed). ADVANTAGE - The composite material inhibits rebound better than the prior art, and uses graphene not only an active material but also as conductive agent to form a better conductive network and improve rate performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene and graphite composite material.
