The invention relates to the technical field of batteries, and provides a zinc-nickel battery negative electrode material, a preparation method and a negative electrode. The zinc-nickel battery negative electrode material includes an active material, a surfactant, a binder, an additive and a dispersant, and the active material is Sulfur-doped carbon coats calcium zincate crystals. The invention improves the negative electrode material of the zinc-nickel battery, uses sulfur-doped carbon-coated calcium zincate crystal as an active material, and adds some surfactants, which can effectively improve the dissolution and deposition of zincate, thereby reducing the self-discharge process. The effect of the generated deactivated zinc particles prevents the effect of the dissolved oxygen generated by the overcharge of the positive electrode on the self-discharge, and improves the service life and efficiency of the electrode. |
