▎ 摘　　要

NOVELTY - A graphene composite material comprises battery electrode composite block main component. The upper end of battery electrode composite block main component is provided with annular filling groove (A). The inner wall of annular filling groove (A) is fixedly installed with at least two electrode filling graphite strips. The inner portion of battery electrode composite block main component is fixedly installed with silicon dioxide block (S1). USE - Graphene composite material for lithium battery electrodes. ADVANTAGE - The composite material has improved strength and electronic connection between silicon dioxide blocks. The arched graphene block improves the electronic density between the silicon dioxide block and battery electrode composite block main component to improve the chemical stability.
