HOUSTON (May 12, 2006) – ExxonMobil Chemical is presenting its polymer
technology capability at the sixth International Advanced Automotive Battery
and Ultracapacitor Conference in Baltimore May 15-19, 2006.
The company is presenting a technical paper jointly with its affiliate in
Japan, Tonen Chemical Corporation, on prototype microporous film for lithium
ion battery (LIB) separators that is expected to dramatically improve LIB
power and safety performance in hybrid-electric vehicle (HEV) applications.
The film 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.
The technical paper "Battery Separators for HEV Application" shares
preliminary findings of ExxonMobil Chemical's and Tonen Chemical's current LIB
separator development activity, as well as expected improvements from
next-generation LIB separator development efforts.
In April, ExxonMobil Chemical and Tonen Chemical announced increased
production capacity at the Nasu Plant in Japan to satisfy strong demand and
high growth in the lithium ion battery separator market.
"The added film lines at the Nasu production facilities enable us to pursue
potential demand growth for customers developing new-generation lithium ion
batteries for hybrid vehicles," said Jim Harris, Polymers senior vice
president, ExxonMobil Chemical Company, a division of Exxon Mobil Corporation.
ExxonMobil Chemical is a global leader in technology, product quality and
customer service, with petrochemical manufacturing and/or marketing operations
in more than 150 countries around the world.
Tonen Chemical Corporation is a leading supplier of separators for lithium ion
batteries. The company's product was adopted for the world's first commercial
lithium ion battery in 1991.
