Supercapacitor Energy Storage Mechanism


Supercapacitor energy storage means using an electric double-layer structure composed of activated carbon porous electrodes and electrolyte to obtain a large capacitance. Unlike batteries that use chemical reactions, the charging and discharging process of supercapacitors is always a physical process. Short charging time, long service life, good temperature characteristics, energy-saving, and environmental protection. There is nothing too complicated about supercapacitors, that is, capacitor charging, and the rest is a matter of materials. The current research direction is whether it can achieve a small area and a larger capacitance. The development of supercapacitors is very fast. At present, new types of supercapacitors based on graphene materials are very popular.


The supercapacitor is a new type of electrochemical energy storage device between traditional capacitors and batteries. Compared with traditional capacitors, it has a higher energy density, and its electrostatic capacity can reach a thousand farads to ten thousand farads. Compared with batteries, it has higher energy density and long cycle life, so it combines the advantages of traditional capacitors and batteries, which is a chemical power supply with broad application prospects.


Supercapacitor energy storage mainly uses the electric double layer formed by the charge separation of the electrode/electrolyte interface, or the Faraday “quasi-capacitance” generated by the rapid redox reaction on the electrode surface and inside to realize the storage of charge and energy. Therefore, supercapacitors have the characteristics of fast charging speed, good high-current discharge performance, ultra-long cycle life, and wide operating temperature range. The supercapacitor energy storage device is mainly composed of a super capacitor bank, a bidirectional DC/DC converter, and corresponding control circuits.
