Ultracapacitor Manufacturers Explain the Development History of Supercapacitors for You

Supercapacitors are electrochemical components developed from the 1970s and 1980s that use polarized electrolytes to store energy. It is different from the traditional chemical power supply. It is a power supply with special performance between traditional capacitors and batteries. It mainly relies on an electric double layer and redox pseudocapacitor charge to store electric energy.

In 1879, Helmholz discovered the properties of double-layer capacitors and proposed the concept of electric double layers, but the use of electric double layers for energy storage is only a matter of recent decades. In 1957, Bcker first proposed that a smaller capacitor can be used as an energy storage device, which has specific energy close to that of a battery. In 1968, Standard Oil Corporation Sohio first proposed a patent for making double-layer capacitors using high-specific surface area carbon materials and transferred the patented technology to NEC. NEC began to produce supercapacitors for the start-up system of electric vehicles in 1979.
