Abstract Lithium ion batteries (LIBs) are one of the most potential energy storage devices among various rechargeable due to their high energy/power density, long cycle life, and low self‐discharge properties. However, current LIBs fail meet ever‐increasing safety fast charge/discharge demands. As main components in LIBs, separator is paramount importance for rate performance LIBs. Among separators, composite separators have been widely investigated improving thermal stability, mechanical...
