The underlying mechanism indicates a specific potential of ∼1 V vs Ag/AgCl for the oxidation of Mn 4+ -to-Mn 7+ at the positive electrode and ∼ -0.8 V vs Ag/AgCl …
NettetBecause of the narrow voltage window the energy and power densities in aqueous electrolytes have only a limited chance of improvement, resulting in the typically lower energy densities of supercapacitors with aqueous electrolytes. Organic electrolytes allow a much wider voltage window of about 3.5 V compared with aqueous electrolytes [83].
