摘要
理想的电池隔膜应该极薄,在电解液中对离子传输没有阻力,有好的电液保持能力,对电极的绝缘电阻无限大,有较高的弯曲性以防止枝晶的生长,高的机械强度防止造成电极短路,并且在电池体系中无化学反应活性,但至今为止,没有一种隔膜可以完全满足上述要求。以化学储能电池的体系为类别,综述了不同电池体系所使用的隔膜类型及发展情况,并对隔膜的发展方向作出展望。
The ideal battery separator would be infinitesimally thin,offer no resistance to ionic transport in electrolytes,provide infinite resistance to electronic conductivity for isolation of electrodes,be highly tortuous to prevent dendritic growths,and be inert to chemical reactions.Unfortunately,in fact,the ideal case does not exist.The separators used in various batteries were reviewed,and the future research trends were pointed out.
