▎ 摘　　要

NOVELTY - The anode comprises a positive electrode body filled in a positive electrode container cavity. The positive electrode body is provided with multiple wire-like positive electrode bodies and taken out from a cavity opening. An electrolyte is filled in the cavity of the positive electrode container. A positive electrode leading-out wire is connected with the positive electrode body. An end of the positive electrode leading-out wire is fixed at an outer unit of the positive electrode container cavity. The air pump is connected between the carbon dioxide absorption device and the positive electrode container. The supported catalyst layer uses graphitized activated carbon or graphene as a supporting layer and supports manganese dioxide, elemental nano silver powder, perovskite-type cobalt oxide, or multiple platinum. USE - Air battery positive electrode. ADVANTAGE - The anode is distributed in the cavity in the form of threadlike, so that the air is easier to disperse in the cavity, thus ensuring the effect, and reducing the raw material cost. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an air battery positive electrode.
