An energy storage device including an active electrolyte, a first electrode and a second electrode is provided. The active electrolyte contains protons and ion pairs with a redox ability. The first electrode and the second electrode coexist in the active electrolyte and are separated from each other. The first electrode and the second electrode respectively include an active material producing a redox-reaction with the active electrolyte or an active material producing ion adsorption/desorption with the active electrolyte. The active electrolyte receives electrons from the first electrode and/or the second electrode so as to perform a redox-reaction for charge storage.

The present invention relates to a metal catalyst composition modified by a nitrogen-containing compound, which effectively reduces cathode catalyst poisoning. The catalyst composition applied on the anode also lowers the over-potential. The catalyst coupled with the nitrogen-containing compound has increased three-dimensional hindrance, which improves the distribution of the catalyst particles and improves the reaction activity.
