Abstract
Supercapacitors are gaining prominence in the realm of energy storage
devices due to their high power density, extended cycle stability, and fast
charge/discharge rates. Supercapacitors are widely used in industries such as service
grids, transportation, consumer electronics, wearable and flexible systems, energy
harvesting, etc. Due to their remarkable high-power performance, high reliability, and
extended lifetime, they are a key electrochemical device for energy storage; as a result,
the worldwide supercapacitor market is rapidly developing. Supercapacitors have a
straightforward basic construction, but different products for various applications
require cells in various configurations. The application of supercapacitors from the
perspective of the industry is the subject of this chapter.
