▎ 摘　　要

NOVELTY - The method involves performing electrochemical deposition to matrix material, obtaining a composite metal elementary substance matrix through vacuum drying, where the elemental metal is zinc or nickel, immersing the composite metal elemental matrix in a graphene oxide solution, obtaining the electrode material after drying, and pre-depositing lithium on the electrode material to obtain a composite lithium metal cathode electrode. USE - Method for preparing composite lithium metal cathode electrode used in lithium metal battery. ADVANTAGE - The formed chemical bond ensures the structure stability while providing the lithium-philic deposition site, so as to guide the lithium metal to uniformly deposit in the cavity to inhibit the dendritic crystal growth. The cycle performance of lithium metal battery is greatly improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: A composite lithium metal cathode electrode; and A lithium metal battery.
