| 摘 要： | 通过NaClO化学氧化Fe(OH)3来制备高纯度的K2FeO4和BaFeO4，并在此基础上研究了BaFeO4和K2FeO4电极的恒流放电性能以及用BaFeO4和K2FeO4制成的锌铁碱性电池的重负荷放电性能。结果表明，BaFeO4和K2FeO4电极在轻、中、重负荷放电下，其放电容量比电解MnO2 的电极提高了56%～116%。AA型锌铁碱性电池的重负荷放电时间比标准碱锰电池提高了95%以上。

| Abstract: | High pure potassium and barium ferrate were prepared through the alkaline oxidation of Fe(OH)3 by hypochlorite. The constant current discharge properties of BaFeO4 and K2FeO4 cathodes were studied. The high load discharge properties of the super-iron(Ⅵ) Zn battery based on BaFeO4 and K2FeO4 were investigated. The experimental results indicate that the discharge capacity of BaFeO4 and K2FeO4 cathode is 0. 56～1.16 times higher than that of conventional EMD electrode under low, medium and high constant load discharge time of the super-iron(VI) Zn battery is over 0.95 times longer than that of standerd Zn/MnO2 during high constant load discharge. |
