Who's behind a better lithium-ion hybrid/EV battery? Why, it's Exxon Mobil {Autoblog Green}

Nov 29th 2007 1:36PM Though you wouldn’t know it from this dumbed-down AP article, Exxon isn’t producing batteries themselves, but rather Tonen Chemical (a Japanese affiliate ExxonMobil Chemical) would be supplying a new separator film to battery manufacturers who need safer batteries for automotive and other specialized markets. Separator films are the thin membranes that keep the battery's positive and negative electrodes apart.

Tonen Chemical's new separator film technology can apparently stand up to much higher heat levels. Tonen’s film will allow battery companies to make larger lithium ion batteries that will not overheat — all without adding additional costs, changing the manufacturing process, or altering the battery's chemistry.

Tonen's been supplying companies with thin film products for nearly 20 years.
