The invention relates to a method for preparing a non-symmetrical electrochemical supercapacitor and electrode materials, and the method comprises the steps of crushing petroleum coke, drying, mixing with an activator according to the proportion, heating, activating, cooling, then using hydrochloric acid for washing, and further using deionized water for washing prepared activated carbon till neutral; carrying out high-temperature graphitization on the obtained activated carbon; and adopting the activated carbon and the graphitized activated carbon for producing a positive electrode and a negative electrode respectively, and finally assembling the non-symmetrical electrochemical supercapacitor. The method can improve the working voltage by 1.1V and improve the specific energy by 8.2 timesin comparison with the method of assembling an electric double-layer capacitor by adopting the pure activated carbon, and be used for producing the electrochemical supercapacitor with high specific energy, high power and long service life.
