1. Durable cycle life. Supercapacitor energy storage is a highly reversible technology. 2. Capable of delivering a high current. A supercapacitor has an extremely low equivalent series resistance (ESR), which enables it to supply and absorb large amounts of current. 3. Extremely efficient.
The energy of a capacitor is stored within the electric field between two conducting plates while the energy of an inductor is stored within the magnetic field of a conducting coil. Both elements can be charged (i.e., the stored energy is increased) or discharged (i.e., the stored energy is decreased).
Electrostatic double-layer capacitors (EDLC), or supercapacitors (supercaps), are effective energy storage devices that bridge the functionality gap between larger and heavier battery-based systems and bulk capacitors. Supercaps can tolerate significantly more rapid charge and discharge cycles than rechargeable batteries can.

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 ...
