摘要
隔膜是电池的重要组成部分,其具有电子绝缘性,因此可以隔离正负极,避免出现短路现象;同时具有离子导电性,可以保证电池的电化学性能。正确评价进而科学使用隔膜可以提高电池的综合性能。本文介绍了电池膈膜的主要测试项目及其对锂电池的参考意义,详细叙述了隔膜各个测试项目的现有测试标准及其测试方法,并对现有方法进行了评述,对锂电池隔膜的测试评价方法提供了参考意见。
The separator is an important component of battery, which has electrical insulation properties, and therefore can be isolated positive and negative electrodes, avoid short circuit. With ion conductivity, the separator also can guarantee the electrochemical performance of the battery. The comprehensive performance evaluation and the correct scientific use of the separator can improve the performance tff the battery. This paper introduces the main test items of the battery separator and its reference meaning to the lithium battery, de- scribed in detail the existing separator test standards and test methods of all test items, and the existing methods are discussed. This review provides reference opinions of the separator evaluation method for lithium battery.
