Review of the Lithium Battery Separator Test Method

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.
