This means that the storage devices must be able to store large amounts of energy during peak hours, until it is to be used during the periods with no energy generation. Boasting incredibly high cyclability (upwards of 100,000 cycles), and fast charge/discharge rates, supercapacitors (SCs) show great promise in the field of energy

The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is
