| 摘 要： | 报道了用纳米 亚微米级铁酸盐材料作正极活性物质的超铁电池的性能,研究了电极中导电剂和添加剂对Zn BaFeO4、Zn K2FeO4和Zn SrFeO4电池的放电特性的影响。结果表明:Zn BaFeO4电池的性能优越于Zn K2FeO4和Zn SrFeO4电池,Zn BaFeO4电池中电极导电剂的最佳用量为20%,添加剂KMnO4将明显改善Zn BaFeO4电池的放电性能,而3%KMnO4+2%Ba(OH)2作添加剂的电池综合性能最佳。

| Abstract: | The performance of super-iron battery with sub-micron to nanometer ferrates as positive material was reported. The influences of conductive material and additive on discharging performance of Zn-BaFeO_4,Zn-K_2FeO_4 and Zn-SrFeO_4 batteries were investigated. The results showed that the performance of Zn-BaFeO_4 battery was superior to Zn-K_2FeO_4 and Zn-SrFeO_4 battery, the optimum amount of conductivity in positive electrode was 20%, the discharging performance of Zn-BaFeO_4 battery would be markedly improved by using KMnO_4 as additive. Taking comprehensive performance of the battery into account , the optimum component of the additive was 3%(KMnO_4+2%Ba(OH)_2.) |
