The supercapacitor is an energy storage device which, in addition to long cycle life (one million), can give energy density higher than parallel plate capacitor and power density higher than battery.
Although the concept of storing energy is not new, batteries have been used to do this since the early 1800s and the way they are being used as storage devices has evolved greatly. They are starting to be used for storing energy from on-peak renewable sources, ready to be released when it is more needed in central, de-central and off-grid
