▎ 摘　　要

NOVELTY - Compound material comprises 95% copper, 0.5% acetylene black, 0.5% polyvinylidene fluoride and 4% graphene/nano silver compound, where the graphene/nano-silver compound is formed by uniformly depositing nano silver particles having a particle diameter of 10-30 nm on a graphene layer having a thickness of 0.8-1 nm, each of the graphene sheets has a multiple of pores on the surface, and the nano silver particles attached are in the form of a face-centered cubic crystal form, and the silver nanoparticle accounts for 2-3.2% of the 4% component amount, and the graphene mass accounts for 0.8-2% of the 4% component amount. USE - The material is useful for preparing a working electrode of lithium battery (claimed). ADVANTAGE - The method provides basis and material for research and development of a high performance and high capacity lithium battery. DETAILED DESCRIPTION - The diagram shows a schematic representation of the preparing a working electrode of lithium battery.
