ExxonMobil Corp said yesterday that a new technology developed by its chemicals business will help the automotive industry overcome some of the overheating hazards with the design of current Lithium ion batteries under heavy demand and help manufactures switch to lighter, more efficient batteries for hybrid and electric vehicles. Battery technology has been a roadblock to bringing a plug-in hybrid to market.
ExxonMobil Chemical and its Japanese affiliate Tonen Chemical said they have developed new separator film technologies that can stand up at higher heat levels. Separator films are thin membranes that keep the battery's positive and negative electrodes apart.
