摘要
以电解法制得的高纯度K2F eO4固体为正极,锌箔或铝箔为负极制成碱性实验电池.通过对Zn-K2F eO4和A l-K2F eO4电池在不同负载下的恒阻放电测试,研究了高铁酸钾电池的电化学性能.结果表明,A l-K2F eO4电池表现出比Zn-K2F eO4电池更为优越的放电性能.基于高铁酸钾在溶液里的不稳定性,提出用A l-K2F eO4电池做贮备电池,并研究其在不同负载、不同温度下的恒阻放电性能及电池的激活时间.
A type of alkaline battery composed of super-iron（K2FeO4） anode and metal cathode （Zn or Al） is developed. The electrochemical properties of Zn-K2FeO4 battery and Al-K2FeO4 battery are studied by testing of their discharge capacity at different loads. The experimental results indicate that the Al-K2FeO4 battery shows good discharge properties compared with the Zn-K2FeO4 battery. Owing to instability of K2FeO4 in the solution, Al-K2FeO4 battery as reserve battery is introduced. The electrochemical properties of Al-K2FeO4 reserve battery are studied by testing of their discharge capacity at different loads and temperatures ,by testing of their activating time at different temperatures.
