Supercapacitors have high power density and long cycle life compared with battery systems, but they still suffer from low energy density at the same time. In order to increase the energy density of supercapacitors, a new type of pseudocapacitor so called colloidal ion supercapacitor has been developed. The colloidal ion supercapacitor can directly use commercial metal salts as electrode materials and the electroactive species can be formed by in-situ electrochemical reactions without the need of additional materials synthesis processes. Colloidal ion supercapacitor can fully utilize the redox reaction of metal cations with multiple oxidation states, which can completely release the stored electrical energy of multiple-valence cations, leadin
