摘要： A wound electric double-layer capacitor suppresses electrochemical reaction on polarized electrode layers, reduces characteristic degradation, and has high reliability. The capacitor has a capacitor element formed by winding positive and negative electrodes with a separator interposed between them, a metal case for storing the capacitor element and an electrolyte for driving, and a sealing member for sealing an opening of the metal case. In the positive and negative electrodes, positive and negative electrode lead wires are coupled to exposed parts of current collectors having polarized electrode layers on their both surfaces, respectively. The negative electrode is wound at least one extra turn from the winding end of the positive electrode of the capacitor element, and hence a part where the polarized electrode layers formed in the negative electrode face each other through the separator is formed on the outermost periphery of the capacitor element.

摘要： When an electrolytic solution of an electric double layer capacitor is prepared, an association is assumed as a model of a solute dissolved in a solvent. The energy of the association and the energies of the reduced association and oxidized association are calculated and a withstand voltage is estimated based thereon. If the withstand voltage exceeds the target value, only the estimated electrolytic solution is actually prepared. As a result, the development time in the development of electrolytic solution is greatly shortened.
