Exxon upgrades lithium car batteries

November 29th, 2007 in Technology / Engineering

U.S. researchers say they've developed a plastic film that will make it easier for automakers to use lithium-ion batteries in electric cars and trucks.

The super-thin plastic sheeting will be unveiled by Exxon Mobil Corp. 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.
