ABSTRACT:
A method for making an electrochemical capacitor is disclosed. A plurality of bipolar electrodes having porous conductive oxide coatings on opposite sides of a thin metal foil are first produced in a fixture assembly using sol-gel processing techniques. A dielectric oxide coating is then applied to one or both conductive coatings using the sol-gel process. A stack of a plurality of the bipolar electrodes with adjacent electrodes separated by a predetermined amount of a solid electrolyte is assembled. The stacked assembly is heated to a temperature above the electrolyte melting point allowing the molten electrolyte to infiltrate the porous coatings. Pressure is applied to the stacked assembly sufficient to produce intimate contact between adjacent surfaces of the bipolar electrodes while expelling excess liquid from between the electrode surfaces. The stacked assembly is cooled in a controlled fashion to produce a laminate structure. This laminate structure may be cut by a diamond saw along the edges and packaged to produce an electrochemical capacitor having the desired capacitance.
