▎ 摘  要

NOVELTY - Graphene composite layered conductive agent supported by carbon nano-tubes, comprises layered graphene and an interlayer carbon nanofibril. The carbon nanometre is generated in situ between layers of the layered graphene, and supports the whole layered graphene. USE - The agent is useful in conductive additive of lithium ion battery. ADVANTAGE - The agent solves the overlapping problem of graphene caused by bond conjugation, enlarges the hole volume and surface specific area of the structure, and improves the conductive efficiency. The method is simple and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene composite layered conductive agent supported by carbon nano-tubes.
