A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit mass or energy per unit volume than electrolytic capacitors, can accept and d. BackgroundThe electrochemical charge storage mechanisms in solid media can be roughly (with some overlap). .
In the early 1950s, engineers began experimenting with porous carbon electrodes in the design of capacitors, from the design of and . is an. .
