电解二氧化锰在碱液中的可逆性

Reversibility of Electrolytic Manganese Dioxide in Alkaline Solution

本文用线性电位扫描法研究了电解MnO_2在40％的KOH溶液中的电极行为和添加剂对MnO_2电极性能的影响。实验结果表明:PbO和Bi_2O_3能提高MnO_2的充放电容量,改善其可逆性。Ni(OH)_2对MnO_2电极在碱液中的第二步反应具有抑制作用,从而改善了MnO_2电极的可逆性。

The electrode behavior of electrolytic manganese dioxide in 40%KOH solution and the effects of additives on it were studied by linear potencial sweep method. This experimental result showed that PbO and Bi2O3 could increase the charge and discharge capacity and ameliorate its reversibility. Ni(OH)2 could restrain the second reaction of manganese dioxide electrode in the alkaline solution,thus improve the reversibility of manganese dioxidj electrode.
