锌空电池空气电极催化剂的研究进展

Advance of air cathode catalysts for zinc-air batteries

论述了目前碱性锌空气电池空气电极用催化剂的种类组成,结构特征,制备方法以及催化剂特点,分析了各种催化剂的优劣和目前存在的问题。对于一次电池空气电极而言,锰氧化物系列催化剂性能较佳,而钙钛矿系列催化剂更适用于二次空气电极。载体的选择和物质的导电性也关系到空气电极整体的阻抗的大小,也是影响空气电极性能的重要因素。

The species composition,structural characteristics,synthesis method,and catalytic property of air cathodes for alkali zinc-air batteries were reviewed in this paper.The advantages and disadvantages and the problem of catalysts was analyzed.For the primary battery,the catalytic property of manganite oxides performed best,while perovskite-type oxides were even more suitable for secondary battery air electrodes.However,due to the resistance reduction,carrier selection and conductivity of materials played an important role in its electrode performance too.
