摘　　要：对比分析了4种镍氢电池隔膜纸的原料种类、物理性能和耐碱性能。JK-1成分含有PP,JK-2、GC-1和GC-2成分含有PE和PP。国产GC系列产品抗张强度和伸长率的提高意义不大;国产GC系列产品透气度高于JK系列,透气度过高会降低电池寿命;GC-2的定量和厚度大于JK系列,厚度大会增大电池内阻;与国外JK系列产品相比,国产镍氢电池隔膜纸应向低定量和低透气率方向发展。GC-2的吸水高度和吸碱高度可以达到JK系列国外产品的水平,GC-1的吸水高度和吸碱高度仍有提升空间;GC系列国内产品的吸碱率提升空间较大;与JK系列国外产品相比,GC-1的碱损失大,并没有达到电池内阻小、寿命长的基本要求。In this study,the main properties of the separator paper of MH-Ni battery made in Japan and the product made in China were compared.The results showed that the domestic separator paper is made of polyethylene fiber and polypropylene fiber.The foreign separator paper is made of polypropylene or polyethylene and polypropylene.The strengthand elongation of domestic separator paper is higher than that of foreign separator paper,but it makes little sense.The grammage and thickness of GC-2is higher than that of other separator paper,but it increases the battery of internal resistance.The permeability of domestic separator paper is higher than that of foreign separator paper,but it will reduce battery life.Compared with the foreign separator paper,the domestic separator paper should be to develop in the direction of low grammage and low permeability.The alkali absorption height and the water absorption height of GC-2meet the requirement of standard of foreign separator.There＇s some room for improvement to the alkali absorption rate of domestic separator paper.The alkaline losing rate of GC-1is greater than foreign separator paper,and it does not satisfy the battery basic requirement of low internal resistance and long working life.
