Houston, Texas (May 8, 2007) - ExxonMobil Chemical's affiliate, Tonen Chemical
Corporation, is now producing on a commercial line its innovative microporous
films for hybrid and electric vehicles (HEV/EV). The films are designed to
meet the safety, reliability and power performance requirements of lithium-ion
batteries (LIB) used in these applications.
The separators are produced using a proprietary wet, bi-orientation
manufacturing process. The new films are co-extruded using specially tailored,
high heat resistant polymers for improved separator properties. These
enhancements to Tonen Chemical’s proven technology ensure consistent separator
quality and easy adoption in HEV LIB applications.
The advanced performance separators exhibit a unique combination of properties
including enhanced permeability, higher meltdown temperature and melt
integrity, without compromising the shutdown temperature and mechanical
strength. The higher meltdown temperature significantly increases the film’s
thermal safety margin.
"Separator quality and safety and supply reliability are critical
considerations for battery and automotive manufacturers to support the rapidly
developing HEV/EV market,” said Jim Harris, senior vice president of
ExxonMobil Chemical." "Producing these next-generation separators on our
commercial lines positions us well to meet the growing market needs.”
This unique combination of properties is the result of close collaboration
between Tonen Chemical, with over 20 years experience in separator research
and process technology, and ExxonMobil Chemical, a global leader in polyolefin
technology. These separators offer the potential to make HEV batteries
lighter, smaller and more durable, contributing to system cost reduction and
improvements in design flexibility.
Tonen Chemical has recently invested in additional, fully-scaleable commercial
production lines to satisfy global automotive industry demands. The new
generation films will be on display at the Advanced Automotive Battery
Conference (AABC) in Long Beach, CA, May 14-18. Samples are available
immediately for advanced HEV / EV lithium-ion battery applications.
