▎ 摘　　要

NOVELTY - Alkaline zinc-manganese battery comprises anode material comprising a conductive agent. The conductive agent contains nano-manganese dioxide-coated graphene material. The nano-manganese dioxide-coated graphene material has needle-shaped nano-manganese dioxide distributed on surface of two-dimensional layered graphene sheet layers and between the sheet layers. USE - Alkaline zinc-manganese battery. ADVANTAGE - The alkaline zinc-manganese battery: adds nano-manganese dioxide to conductive agent to coat the graphene material; improves the dispersibility of the conductive agent and anode active material; reduces the battery internal resistance; reduces polarization; makes the electronic transmission smooth; reduces the obstruction of the ion load; improves the utilization rate of the active substance; and improves the discharge performance of the large, medium and small current of the battery at the same time.
