▎ 摘　　要

NOVELTY - The negative electrode (10) has a buffer layer (20) positioned on a lithium metal anode to prevent damage to the anode. A protective layer (30) is positioned on the buffer layer to inhibit dendrite growth of the electrode. The buffer layer comprises graphene oxide, and the protective layer comprises metal oxide. The metal oxide comprises magnesium gallium zinc oxide or aluminum zinc oxide. USE - Lithium metal negative electrode for lithium ion battery for use in electric vehicles and drones. ADVANTAGE - The dendritic growth of the lithium metal negative electrode is suppressed by the protective layer. The bonding between the buffer layer and the metal oxide protective layer is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a multilayer lithium metal negative electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a multilayer lithium metal negative electrode. 10Lithium metal anode 20Buffer layer 30Protective layer
