An Supercapacitors, sometimes abbreviated as EDLC, is a storage device that is classified as a capacitor. Compared to another familiar electricity storage device, the rechargeable battery, a capacitor has inferior energy density (amount of energy stored per unit of mass or volume).
The comparative features of supercapacitors and other devices For the practical application of SCs, important aspects such as device efficiency, energy density, power density, rotational efficiency, and environmental protection should be considered in the commercial and market production of SCs.
The term ‘supercapacitor’ refers to the electric double-layer capacitor (EDLC). Other devices – including pseudocapacitors, which store energy electrochemically in a manner akin to that of batteries, and hybrids that store energy both electrochemically and electrostatically – are under development, but this article will focus on EDLCs.
From surface-mounted and coin-type capacitors to radial lead-type, laminate-type, and large-capacity screw terminal type products, Supercapacitors available on the commercial market come in a wide variety of shapes and sizes.
