TOKYO (October 18, 2006) -- ExxonMobil Chemical’s affiliate in Japan, Tonen
Chemical Corporation (TCC), will feature its innovative microporous film
lithium ion battery (LIB) separators designed for hybrid electric vehicle
(HEV) applications at the 22nd International Battery, Hybrid and Fuel Cell
Electric Vehicle Symposium & Exposition (EVS 22), Yokohama, October 23-28,
booth A-62.
TCC's advanced performance separators are expected to significantly improve
LIB power and safety performance in HEV applications. They 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 is committed to LIB separator technology development and production
process improvements. It 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. TCC has collaborated with ExxonMobil
Chemical, one of the global polyolefins technology leaders, to develop a new
generation of advanced performance LIB separators for HEV.
"The collaboration combines TCC’s outstanding process technology and
ExxonMobil Chemical’s advanced polymer science technology,” according to Junya
Ishiyama, president of Tonen Chemical Nasu (TCN), wholly owned affiliate of
TCC. "Our separators offer broader design flexibility with enhanced
performance target to capture cost benefits of LIB HEV."
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. In addition, the separators were developed for safety, quality and
value featuring excellent melt down and shut-down properties, and uniquely
balanced LIB power capacity and density.
