description The invention relates to a silver-carbon composite metal lithium negative electrode and a preparation method thereof. The technical problems of lithium dendrite breeding and non-uniform lithium deposition behavior of the existing metal lithium negative electrode are mainly solved. According to the technical scheme, the silver-carbon composite metal lithium negative electrode is characterized in that a negative electrode material is attached to the surface of a copper foil, and the negative electrode material is composed of a silver-carbon composite negative electrode material and deposited lithium. The preparation method comprises the following steps: 1) soaking carbon-based material resin in a silver nitrate solution, and fully reacting to obtain Ag-substituted ion exchange resin microspheres; (2) carrying out carbonization treatment; (3) preparing the silver-carbon composite negative electrode material into slurry, and smearing the slurry on a copper foil to obtain the copper foil with a silver-carbon compo
