EN In electrochemical capacitors, also known as supercapacitors (SC), electrolytes and electrodes are the most important constituents and control the main characteristics of the device. The high energy density of a SC can be obtained by designing functional electrode materials along with appropriate electrolytes. Redox activity represents a groundbreaking boost to the performance of SCs by increasing the charge storage capability through Faradaic reactions. This can be accomplished by using electrolytes with redox additives or by combining electrode materials showing charge transfer phenomena. Among many pseudocapacitive compounds, transition metal disulfides (TMDs) have been considered for use in SCs owing to their remarkable properties. In this paper, the electrochemical performance of SCs and the current state-of-the-art of redox activities provided by electrolytes and electrodes are discussed.
