Abstract
An aqueous electrolyte for a capacitor contains at least one transition metal complex. An aqueous electrolyte containing at least one transition metal complex can be used in a supercapacitor, in a pseudocapacitor, or in a hybrid supercapacitor. A hybrid supercapacitor contains an aqueous electrolyte, which contains at least one transition metal complex.
Claims6
