Customer ServiceIt has a lower energy density than a battery. It has a better energy density than a capacitor. Charging and discharging rates are faster than a battery because it stores energy directly onto the plates. Because of the conversion of chemical energy to electrical energy, charging and discharging rates are considerably slower.
