Abstract: In this paper, the main function and performance, research and present situation of home and overseas of microporous membranes made of polyolefin materials are summarized, which are used in Li-ion battery as separators. The principles, process of dry and wet methods are emphasized. The modification and new type of battery separator are also discussed. At last, the development trend of separator is predicted.

Key words: lithium-ion battery, separator, progress
