ExxonMobil Chemical Affiliate in Japan to Highlight Lithium-Ion Battery Technology for Hybrids at EVS 22
ExxonMobil Chemical’s affiliate in Japan, Tonen Chemical Corporation (TCC), will feature its microporous film lithium-ion battery (LIB) separators designed for hybrid electric vehicle (HEV) applications at the upcoming 22nd International Battery, Hybrid and Fuel Cell Electric Vehicle Symposium & Exposition (EVS 22), Yokohama, October 23-28.
TCC expects that its advanced performance separators will significantly improve LIB power and safety performance in HEV applications. The separators offer 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.
TCC has more than 20 years of research and development in LIB separators and has supplied its proprietary separators for the world’s first commercial rechargeable LIB [in 1991]. TCC has collaborated with ExxonMobil Chemical, one of the global polyolefins technology leaders, to develop a new generation of advanced performance LIB separators for HEVs.
The collaboration combines TCC’s outstanding process technology and ExxonMobil Chemical’s advanced polymer science technology. Our separators offer broader design flexibility with enhanced performance target to capture cost benefits of LIB HEV.—Junya Ishiyama, president of Tonen Chemical Nasu (TCN), wholly owned affiliate of TCC
TCC will showcase the advanced performance separator films which have higher melt integrity and a significant reduction in heat shrinkage, while maintaining good permeability and tensile strength when compared to standard separators.
Tonen Chemical Corporation manufactures petrochemical products such as ethylene and propylene in Japan, and sells them as the raw materials for polyethylene and other polymers to its affiliate, Nippon Unicar Corp., and other customers.
