▎ 摘　　要

NOVELTY - Zinc-free cathode zinc air battery comprises discharge positive electrode, a charging positive electrode and a zinc-free negative electrode. The zinc-free negative electrode is copper, tin, silver, gold, indium, bismuth, carbon paper, carbon felt, or a composite material formed by metal. USE - The zinc-free cathode zinc air battery is useful in the field of fuel cell. ADVANTAGE - The zinc-free cathode zinc air battery: can induce generation of zinc-free dendrite surface; avoids the corrosion of electrolyte to the zinc free cathode; prolongs the working time of the battery; improves the circulation ratio capacity of the secondary zinc air battery, so that it can meet the commercial application requirement. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the zinc-free cathode zinc air battery. (Drawing includes non-English language text).
