Hipore™ lithium-ion battery separator

Hipore™ is a microporous polyolefin sheet which prevents the anode and cathode from contacting one another and causing a short circuit, while enabling lithium ions to pass back and forth during charging and discharging. While market growth continues in mainstream LIB applications for portable devices such as smartphones and tablet PCs, significant additional growth is forecasted in electric vehicle applications. Asahi Kasei will continue to expand capacity in line with demand growth while advancing the global expansion of Hipore™ operations to meet emerging customer needs.
