摘　　要：研究了正负极中加入添加剂对MH/Ni电池内压和内阻特性的影响 ,结果表明负极中添加金属钴及其氧化物和氢氧化物可有效降低电池的内压 ,正极中加入锰、镉、钴及它们的氧化物和氢氧化物可明显提高电池内部气体的复合性能 。The effects of the additives added in positive and negative electrodes on the properties of MH/Ni battery internal pressure and impedance were discussed.It showed that metal cobalt,its oxide or hydroxide added in negative electrode could decrease effectively the internal pressure.Metal manganese,cadmium and cobalt,and their oxide or hydroxide added in positive electrode could increase the internal pressure recombination properties,and the battery impedance could be also lowered with the addition of these additives.
