▎ 摘　　要

NOVELTY - A lithium alloy negative electrode film comprises a base foil material, and an alloy film layer arranged on the base foil material. The alloy film layer comprises lithium metal, and metal or inorganic non-metal. The mass ratio of metal or inorganic non-metal, and lithium metal is (0.01-50):100. USE - Lithium-alloy negative electrode film used for secondary lithium metal battery e.g. liquid lithium metal battery, semi-solid lithium metal battery, quasi-solid lithium metal battery, or solid lithium metal battery (all claimed), vehicle and 3C electronic equipment. ADVANTAGE - The lithium alloy negative electrode is flat and smooth, and has no wrinkle defect and burr. The electrode has better electrochemical performance, improves the cycle performance of the lithium metal battery and can be prepared by simple method, is safe and efficient, easy to ensure large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the lithium alloy negative electrode film.
