ExxonMobil Chemical will introduce new co-extruded separator grades for hybrid and electric vehicle batteries at the Advanced Automotive Battery Conference (AABC). It developed two new separator grades with co-extrusion technology to meet more demanding battery requirements. The new co-extruded grades offer enhanced permeability, improved strength, reduced heat shrinkage and higher rupture temperature to improve battery safety and performance.

This technology platform builds on ExxonMobil Chemical’s twenty years of innovation and experience in lithium-ion battery separators. Production from existing commercial lines provides ExxonMobil Chemical with the flexibility to scale-up to meet the anticipated growth in demand for hybrid and electric vehicle batteries. It will help speed the adoption of smaller and more powerful lithium-ion batteries in next generation hybrid and electric vehicles.
