ExxonMobil's affiliate, Tonen Chemical Nasu Co. Ltd. (TCN), is developing a film for lithium ion battery (LIB) separators that is expected to significantly improve LIB power and safety performance in hybrid-electric vehicle (HEV) applications. The film is thin, yet strong, helping to increase the stability and reliability of lithium ion batteries. Its homogeneous pore structure provides exceptional performance that maximizes battery safety. The film closes its pores if excessive heat is generated during the chemical reaction in the battery. This minimizes the potential for short circuits and battery rupture. It offers the potential to make HEV batteries lighter weight and smaller, thereby contributing to HEV system cost reduction and to improvements in design flexibility and durability. This paper shares preliminary findings of current LIB separator development activity, as well as expected improvements from next-generation LIB separator development efforts.
