How Capacitors and Batteries Differ. Capacitors and batteries are similar in the sense that they can both store electrical power and then release it when needed. The big difference is that capacitors store power as an electrostatic field, while batteries use a chemical reaction to store and later release power.
They act as a link for energy-power difference between a traditional capacitor (having high power) and fuel cells/batteries (having high energy storage). In this perspective, a worldwide research has been reported to address this and rapid progress has been achieved in the advancement of fundamental as well as the applied aspects of …

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.
Energy storage (in the tank) and energy conversion (in the fuel cell) are thus locally separated. In electrochemical capacitors (or supercapacitors), energy may not be delivered via redox reactions and, thus the use of the terms anode and cathode may not be appropriate but are in common usage.
