摘　　要：比较普通型聚烯烃隔膜、聚丙烯接枝膜和聚烯烃磺化隔膜材料对MH/Ni电池容量、内阻、输出功率和自放电性能的影响。结果表明,隔膜对电池的容量影响不大,磺化隔膜制作的电池的内阻比其他两种的小,输出功率更大。使用磺化隔膜的电池的荷电保持率最佳,使用接枝隔膜的次之,使用普通聚烯烃隔膜的最差。综合容量、内阻和自放电性能,采用磺化隔膜可以改善MH/Ni电池的性能。The effects of the separators made of common polyolefine, grafting polypropylene and sulfonated polyolefine on Ni/MH battery are investigated. The results show that the separator has little effect on the battery capacity. The battery internal resistance is decreased and the power is increased by using the sulfonated separator. The self-discharge performance of the battery made by sulfonated separator is the best, followed by the grafting polypropylene separator, and the common polyolefine separator lines in the third. By comparing the characteristics of capacity, internal resistance and self-discharge, it is concluded that the sulfonated separator can improve the performance of Ni/MH significantly.
