PURPOSE:To make it possible to lower ESR(equivalent series resistance) of an electric double-layer capacitor by heat-treating the activated carbon of a carbon paste electrode at the temperature of 1000 deg.C or higher. CONSTITUTION:In a carbon paste electrode 3a for electric double-layer capacitor which uses mixture of powder activated carbon and electrolytic solution for the electrode, powder activated carbon is heat-treated, and the temperature of heat treatment is made to above 1000 deg.C. When the temperature for heat treatment of the activated carbon is raised, the ESR of the electric double-layer capacitor lowers at above 1000 deg.C and diminishes to about half the conventional one. Hereby, the electric double-layer capacitor with ESR lower than the conventional one can be realized. |
