▎ 摘　　要

NOVELTY - A composite electrode comprises a foamed metal, graphene and transition metal compound. The foamed metal serves as a supporting frame of the composite electrode. The graphene is uniformly deposited on supporting frame. The transition metal compound is uniformly deposited on the graphene. USE - Composite electrode for negative electrode of graphene lithium ion battery. ADVANTAGE - The composite electrode improves the lithium-ion battery capacity and cycle stability, and has high practical value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite electrode for negative electrode of graphene lithium ion battery.
