The invention provides a method for forming an aqueous super capacitor. In the method, quantitative electrolyte is added by a vacuum injection method, and the aqueous super capacitor is charged and discharged for activation through different current values in multiple stages. Therefore, the method effectively improves the powder dropping phenomena of pole pieces in the process of formation and enhances the product properties of current leakage and internal resistance of the super capacitor. Meanwhile, the method has the advantages of greatly shortening the forming period and improving the production efficiency.
