ExxonMobil Develops New Films for Safer Lithium-Ion Batteries

With the demand for lithium-ion batteries expected to increase, ExxonMobil takes the initiative in making sure that they distribute quality and efficient batteries once that happens. ExxonMobil Chemical continues to extend its technology leadership with the development of two new grades of V series co-extruded battery separator films. These new developmental grades will help make lithium-ion batteries (LIB) safer than ever before for hybrid and electric vehicles, power tools and electronic devices including laptop computers.

Featuring improved thermal stability and lower shutdown temperature for a higher safety margin, the developmental grades add to the company’s battery separator film portfolio that includes the award-winning V-series separator films introduced in 2007. Based on the same advanced co-extrusion technology platform and proprietary wet bi-orientation manufacturing process as V-series separator films, the developmental grades can help prevent thermal runaway in batteries while providing LIB designers more flexibility in selecting electrode systems and formats in battery designs to improve power and capacity density.

ExxonMobil Chemical currently manufactures battery separator films in Nasu, Japan, and is building a manufacturing facility in Gumi, Korea, to accommodate additional demand and serve global customers reliably and efficiently. The new manufacturing plant will be completed in 2010.
