Researchers at Michigan Technological University are working on an asymmetric capacitor, a new type of electrical storage device that’s half capacitor, half battery. “Being lighter will give them a real advantage in handheld power tools and consumer electronics and hybrid electric vehicles are another potential market, since an asymmetric capacitor can charge and discharge more rapidly than a normal battery, making it useful for regenerative braking.
