Exxon Says New Battery Film May Find Way into Electric Cars
Exxon Mobil Corp. believes it has found an answer to a problem that has bedeviled the auto industry in recent years: using rechargeable lithium-ion batteries, like those found in cell phones and laptops, to power cars and trucks.
This weekend, at a conference in Anaheim, Calif., Exxon Mobil will unveil a super-thin plastic sheeting the company says can improve the power, safety and reliability of lithium-ion batteries for use in automobiles.
Exxon Mobil considers the film a breakthrough because it allows battery makers to build smaller and cheaper battery systems — removing key obstacles that have kept automakers from building hybrid and electric vehicles on a wide scale.
