摘　　要：高温性能和倍率性能的改善是混合动力车用MH/Ni电池实用化中的关键问题.采用目前3种广泛使用的β-Ni(OH)2制造了容量为6 Ah的D型电池,对比研究了3种电池在常温及60℃下的充放电性能,同时结合材料的微结构分析得出包覆4.5%Co(OH)2的β-Ni(OH)2综合性能较佳.For an applicable HEV,the key issue at present is to improve high temperature and rate performances of MH/Ni batteries.In this paper,three kinds of β-Ni（OH）2 with different means of cobalt additives addition were investigated by charge/discharge tests in D-type cells with 6 Ah capacity at ambient and 60 ℃,respectively.Combining with the information obtained from the micro structures changes of these materials,the conclusion is obtained that the best kind of positive material for MH/Ni batteries in HEV is β-Ni（OH）2 coated with 4.5%Co（OH）2.
