Supercapacitors offer fast charge-discharge rates, long cycle life, and wide temperature range, but have lower energy density, higher self-discharge, and cost compared to batteries.

A is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded over 100 years ago. Most older companies were founded during the era, which includes the era and post war era. As the demand for advanced electronics con.

Unlike traditional capacitors, which use dielectric material to store energy, supercapacitors store energy through the electrochemical double-layer effect and, in some cases, through a reversible faradaic redox reaction.

Supercapacitors are used in applications requiring many rapid charge/discharge cycles, rather than long-term compact energy storage: in automobiles, buses, trains, cranes, and elevators they are used for regenerative braking, short-term energy storage, or.
