| 摘 要： | 用过渡金属氧化物作为ＭＨ／Ｎｉ电池的负极添加剂，研究了它对ＭＨ／Ｎｉ电池容量、放电电压、电池内压和循环性能的影响。加人２％的新型负极添加剂，可以在保证电池容量不受影响的前提下，使ＭＨ／Ｎｉ电池的放电中值电压升高约２０ｎＶ，以１Ｃ倍率电流充电时的最大电池内压减少０．４ＭＰＡ，并显著提高电池循环性能。以１Ｃ倍率快速充放测试徨４００次时，其容量保持率在９０％以上，放电中值电压变１．２１６Ｖ。

| Abstract: | The mixture of several kinds of transition metal oxide has been used as an additive of metal hydride electrode in MH/Ni battery. The effects of the additive on the properties of MH/Ni battery were studied. Compared with the former MH/Ni batteries, the new ones with two percent novel additive in metal hydride electrode have excellent performances such as higher discharge voltage(by 20mV, approx.), lower charge inner pressure(by 0.4MPa, approx.), and longer cycle life when charged/discharged at 1C rate. |
