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.
