▎ 摘  要

NOVELTY - The electrode has a metal layer formed by a metal lithium layer or a metal lithium alloy layer. A mixed electric conductive layer and a mixed electric conductive layer are connected with a mixed electric conductive material layers containing metal lithium, where the weight ratio of the metal lithium and the mixed conductive material in the mixed electric conductive layer is 1:0.05 to 1 and the weight ratio of the metal lithium and the mixed conductive material in the mixed electric conductive layer is 1:0.1 to 10. USE - Lithium negative electrode for a lithium secondary battery (Claimed). ADVANTAGE - The electrode provides uniform deposition site for metal lithium by the mixed electric conductive material, thus inhibiting formation and growth of lithium dendritic crystal. The mixed electric conductive layer and the current collector has better adhesive property and better mixed electric conductive layer and the mixed electric conductive layer for relieving the volume effect of the metal lithium in the electrochemical reaction process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium negative electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a lithium negative electrode for a lithium secondary battery.
