The Application Study On Of Single Carbon Supported Catalysts In The Zinc-air Battery

In recent years, the growing energy crisis, the development of new energy has been constantly researched. The performance of the zinc-air batteries for its high-capacity, high-efficiency, low-cost, discharge stable, clean pollution, security, raw materials, renewable, etc. has attracted the attention of researchers to solve the energy problem. So the zinc-air batteries have great market prospects. Based on the previous studies, this paper has done some research on zinc-air batteries as following:Comparison of the Co-Mn-O/C (single carbon supported oxidation of cobalt and manganese) catalyst and single carbon supported Ag catalyst, carbon loading silver cobalt and manganese dioxide catalyst on properties of zinc air battery, and the acetylene black and activated carbon ratio in the catalyst layer, which using the Co-Mn-O/C catalyst; then study the cobalt manganese molar ratio of Co-Mn-O/C catalyst, and the influence of Co-Mn-O/C catalysts prepared by different temperature on the battery zinc air battery; this paper also by adding charging auxiliary electrode, a study of Charge and discharge has been conducted on zinc air battery by the three electrodes system. And making the air electrode, designed and assembled the zinc air battery and a small button battery. The production of battery by electrochemical test, results showed that:with Co-Mn-O/C as catalyst in the battery compared to other catalysts has better volt-ampere characteristics, And the molar ratio of cobalt and manganese is1:3, the preparation temperature is350℃, the Co-Mn-O/C catalyst has the best catalytic activity. The battery can realize Charge and discharge after adding auxiliary charging electrode, the zinc plating additive DE is6mL/L and graphite as auxiliary charging electrode, the battery has better charge and discharge depth. Compared with the commercialization zinc-air battery production, the button battery has greater capacity.
