“In a patent application, an Austin-based startup called EEStor promised “technologies for replacement of electrochemical batteries,” meaning a motorist could plug in a car for five minutes and drive 500 miles roundtrip between Dallas and Houston without gasoline. EEStor’s secret ingredient is a material sandwiched between thousands of wafer-thin metal sheets, like a series of foil-and-paper gum wrappers stacked on top of each other. Charged particles stick to the metal sheets and move quickly across EEStor’s proprietary material. The result is an ultracapacitor, a battery-like device that stores and releases energy quickly.”
