The separator is an important part of the lithium battery. The separator is electronically insulating to avoid short-circuits; at the same time, it has ion conductivity to ensure the electrochemical performance of the battery. The diaphragm has a significant impact on the capacity, cycle performance, charge-discharge rate, etc. of the battery; especially has a greater impact on the safety of the battery. Therefore, the quality of the battery separator directly affects the overall performance of the battery. We can use some measurable physical and chemical indicators and electrochemical indicators to judge the impact on battery performance. In 2018, the National Alkaline Battery Standardization Technical Committee and China Chemical and Physical …
