Boffins at the Rice lab have developed anodes comprising porous carbon made from asphalt that showed exceptional stability after more than 500 charge-discharge cycles which means batteries can be charged 20 times faster.

A high-current density of 20 milliamps per square centimeter demonstrated the material's promise for use in rapid charge and discharge devices that require high-power density. The Tour lab previously used a derivative of asphalt -- specifically, untreated gilsonite, the same type used for the battery -- to capture greenhouse gases from natural gas.
