铝半燃料电池研究

Study of aluminum hydrogen peroxide battery

采用化学沉积法制备了Au/Ni催化阴极,并组装成90 cm^2 Al/H_2O_2电池,采用微酸性阴极电解液进行放电,放电时间长达6 h,平均电压1.466 V,H_2O_2利用率可达92.8%。通过设计分配框结构,将电极面积扩大至500 cm^2,装配了两单体组合电堆,放电506 min,本体比能量达到404.1 Wh/kg。

In this article, Au/Ni electro-catalytic cathode was prepared by a chemical deposition method, and Al/H_2O_2 battery was assembled and discharged with acidic catholyte for almost 6 hours. The average voltage is 1.466 V, and H_2O_2 utilization is up to 92.8%.
