This disclosure discloses an aqueous high-voltage electrolyte and its preparation method, as well as a supercapacitor, belonging to the field of supercapacitor technology. The preparation method of the aqueous high-voltage electrolyte includes: adding an electrolyte salt to deionized water and stirring until the electrolyte salt is completely dissolved to obtain a mixed solution; adding a high-voltage additive and a hydrogen-eliminating additive to the mixed solution, and stirring to obtain the aqueous high-voltage electrolyte. This disclosure utilizes the synergistic effect of two additives, which preferentially adsorb at the electrode / electrolyte interface. By adjusting the interfacial double-layer structure, disrupting the hydrogen bond network of water molecules, or forming a protective layer, these additives effectively increase the water decomposition overpotential, thereby achieving a stable widening of the operating voltage window without significantly altering the basic composition and physicochemical properties of the electrolyte.

This invention relates to an IrO2@NiRuO3 formulation for PEM water electrolysis. x This invention relates to an anode catalyst, its preparation method, and its application, belonging to the technical field of catalysts for hydrogen production via water electrolysis. The method involves mixing ruthenium salt, nickel salt, and carbon material in an acid solution, followed by rotary evaporation and drying. The mixture is then successively calcined under a reducing atmosphere and calcined in air, followed by immersion in an acid solution, and finally washed and dried to obtain NiRuO. x Add iridium precursor and NiRuO to the alcohol solvent system x After stirring and impregnation for 1-4 hours, nitrate is added and stirring and impregnation continues for 0.25-1 hour. The solvent is then removed to obtain NiRuO supported on the iridium precursor. x Finally, the anode catalyst is obtained by calcining at 480-520℃ for 10-60 minutes in air, followed by washing and drying. The anode catalyst of this invention achieves high catalytic activity and improved long-term stability under high current density conditions in high-pressure PEM electrolysis.
