Tonen's New Film Enhances Lithium-ions

ExxonMobil Chemical and ExxonMobil’s Japanese affiliate, Tonen Chemical, have developed new film technologies for lithium-ion batteries to improve the energy efficiency and affordability of hybrid and electric vehicles. These technologies, shown at the 23rd EVS in December, are expected to significantly enhance the power, safety and reliability of Li-ion batteries, thereby helping to speed the adoption of smaller, lighter Li-ion batteries into vehicles.

Separator film is an integral part of battery system design and critical to overall performance. ExxonMobil Chemical’s new technology platform builds on 20 years experience in Li-ion battery separators, applying advanced polymer and process technologies with flexibility to tailor products to manufacturer requirements.
