Carbon materials used as primary electrode materials for electrochemical capacitors Among them, microporous-activated carbons with high specific surface area are the most commonly used electrode materials for EDLCs. In principle, owing to the energy storage mechanism, a high specific surface area is important for storing a large amount of energy.
The battery-like and capacitor-like electrodes depend on their energy storage mechanisms. They have many different electroactive materials such as carbon-based materials, alloys, transition metal oxides, and conducting polymers. If the energy density is higher than power density, it can mostly be called as battery-like electrode.

Mostly positive electrode has carbon-based materials such as graphite, graphene, and carbon nanotube. Na + ions diffuse into these materials in the reverse process (battery discharge). These ions return back to negative electrode. During the process, a device or LED lamb can be enlighted by the production of required energy.
