Inorganic Electrolytes in Supercapacitor

Supercapacitors are considered promising energy storage systems due to their high power density, fast charge-discharge, long service lifetime, wide operating temperature range and excellent capacitance retention. The electrochemical performance of the supercapacitors depends upon numerous factors such as nature of electrode materials, type of electrolyte and separator thickness, etc. Among these factors, electrolyte used in supercapacitor plays an important role in deciding final characteristics of supercapacitors. In recent decades, tremendous research work has been on the development of novel electrolytes and electrode/electrolyte configurations. In this chapter, we aimed to focus on the role of inorganic electrolytes used in supercapacitors.
