The invention discloses an integrated super capacitor electrode material preparation method and applications thereof. The preparation method comprises the following steps: cobalt salt, nickel salts, and sulfonium salt are dissolved in a solvent and are uniformly stirred and mixed; the above solution is transferred to a high pressure reaction kettle, and an electrode carrier is put in the kettle; the high pressure reaction kettle is sealed and then placed at a temperature of 100 to 160 DEG C for reaction for 2 to 12 h; and the electrode carrier is washed and dried to obtain the integrated super capacitor electrode material. The invention also provides applications of the above integrated super capacitor electrode material in manufacturing of the super capacitor. Raw materials of the preparation method of the invention are cheap and easy to obtain, the synthesis technology is simple and easy to realize, the product quality is stable, the technology repetition performance is good, and the electrode preparation material has excellent super capacitance performance.
