The super-thin plastic sheeting will be unveiled by Exxon Mobil Corp. (NYSE:XOM) at a conference this week in Anaheim, Calif., the Houston Chronicle said Wednesday.

The company said the plastic film, developed with Japanese affiliate Tonen Chemical, will make lithium-ion batteries safer, stronger and more reliable. The film squeezes multiple layers of plastic into a single sheet the thickness of a human hair, allowing the batteries to run at higher temperatures and produce more power without overheating.
