    New capacitor material could make them practical for EVs
    1185206160

    One of the means that electrically powered vehicles used to maximize their range is regenerative braking where the kinetic energy of the vehicle is recaptured during deceleration and than released during acceleration. The problem is that most batteries can't absorb energy quickly enough to capture ...
