Supercapacitors are further divided into electric double-layer capacitors (EDLC), Faraday capacitors, and hybrid capacitors. Mainly through the highly reversible polarized electrolyte electrostatic physical adsorption mode of energy storage, is a new type of green energy storage device between the traditional capacitor and rechargeable battery, it has the characteristics of short charging time, good temperature characteristics, energy saving and green environmental protection, cycle charging and discharging up to hundreds of thousands of times, life span of more than ten years, has been widely used in intelligent three meters, intelligent data protection, computer peripherals, new energy automotive electronics, smart home, intelligent industrial control, 5G terminals and other fields.
