This study focused on investigating low-cost but high-performance catalyst materials used for the air cathode of the aluminum-air battery. Nickel, in the form of Ni(OH)2, was used as the catalyst because it is abundant and low-cost. The activated carbon sheet was used as the substrate to load the catalyst. The solvothermal synthesis method was used to synthesize the catalyst. The advantage of the solvothermal method is that the particle size can be reduced under high temperature and pressure conditions. The operation of some types of air-cathodes was examined. UV-ozone treatment of the air-cathode has also been investigated to enhance the performance of the battery.

镍基空气阴极的制备与评价

这项研究的重点是研究用于铝空气电池的空气阴极的低成本但高性能的催化剂材料。Ni（OH）2形式的镍用作催化剂，是因为其价格昂贵且价格低廉。活性炭片用作基材以负载催化剂。溶剂热合成法用于合成催化剂。溶剂热法的优点是可以在高温和高压条件下减小粒径。检查了某些类型的空气阴极的操作。还已经研究了空气阴极的紫外线臭氧处理，以增强电池的性能。
