Organic electrolytes in electrochemical supercapacitors: Applications and developments.

• Applications of organic electrolytes in EDLCs, pseudocapacitors and hybrid-capacitors. • Energy density of ESs can be enhanced by using organic electrolytes with wide potential range. • Effects of pore size, electrode-electrolyte interaction, impurities, temperature and many other factors on performance of ESs are discussed. • Methods for the development of newer organic electrolytes have been presented. The article presents an overview of applications of organic electrolytes in electrochemical supercapacitors. Organic electrolytes with large potential range dominate the commercial market. There are some associated drawbacks with organic electrolytes such as relatively high cost, smaller specific capacitance, high resistance, greater flammability, volatility, and toxicity. To encounter these disadvantages, methods for the development of newer organic salts and solvents are also discussed. [ABSTRACT FROM AUTHOR]
