(a) Discharging behaviours of the ACF device for constant currents of 20 nA, 100 nA, 500 nA, 2.5 μA, and 12.5 μA after 2 mA–10 V charging for 50 s. (b) Discharging time and IR drop for 2 mA-rapid charging/1μA-discharging up to 30 times. (c) Applied voltage dependency of stored energy. (d) An LED powered by the ACF device.
