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.
