Provided is a super electrochemical capacitor including two electrode plates having the same size but different quantities of electric charges or electric charge densities without increasing the volume of the capacitor to increase the quantity of electric charges, capacitance and usable voltage range of the capacitor, to thereby obtain high voltage and super capacitance. The super electrochemical capacitor includes two electrode plates having different quantities of electric charges and similar sizes. The two electrode plates are spaced apart from each other by a dielectric layer or collector layer. The two electrode plates have different quantities of electric charges or electric charge densities while maintaining the sizes thereof. The two electrode plates have different porosities or bulk densities such that the electrode plates have different quantities of electric charges or electric charge densities. The ratio of the quantity of electric charges or electric charge densities between the two electrode plates is 1:0.2 to 0.95.
