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.
Keywords: Electrolytes, Energy storage, Electrochemical supercapacitors.
