The facility will have the capacity to produce more than 30 million square meters of film per year, with significant opportunity for future expansion. Start-up is expected in 2009.

The separators offer enhanced permeability, improved strength, reduced heat shrinkage and higher rupture temperature to improve battery safety and performance. (Earlier post.) The new family of co-extruded films will also continue to multiply, according to Pat Brant, chief scientist for ExxonMobil Chemical, based on customer need and input. Those needs can vary with a number of factors, including battery format and chemistry.
