1 Introduction</h5> Lithium-ion battery separator, placed between anode and cathode of lithium battery and serving as the electrolyte reservoir to enable ionic transportation, is a high value-added material with the highest technical barrier among lithium-ion battery materials [1,2] . The battery separator is expected to be thin and highly porous but with enough physical strength to balance the mechanical and electrical separation between electrodes  . In recent years, intensive requirements of rechargeable lithium batteries with high energy and power density in high-powered electric vehicles and energy storage devices, prompt urgent scientific and technical issues to produce high-performance separators with high porosity (around 50–70%), strong mechanical properties (puncture strength of about 5 N) and reliable safety. Specifically in case of overheating, the separator should have the inherent ability to shut down the circuit while its mechanics is still remained. However, most microporous membranes available in the market can gain only around 40% porosity and have relatively poor mechanical strength and a melt temperature lower than 150 °C. For electric vehicles and other high working load applications, the current battery separators are still deficient in comprehensive characters of high porosity (correspondingly ionic current), strong mechanical strength and reliable safety.
