Electrical double layer capacitor and portable electronic apparatus equipped with electrical double layer capacitor
An electrical double layer capacitor has an electrolyte comprised of a non-aqueous solvent and a supporting salt dissolved in the non-aqueous solvent. A pair of polarizing electrodes are disposed in confronting relation with one another. A separator is disposed between the polarizing electrodes. The supporting salt contained in the electrolyte exists only in regions proximate a surface of the polarizing electrodes when the electrical double layer capacitor is fully charged. The non-aqueous solvent contains a preselected amount of dissolved supporting salt calculated from a surface area of the polarizing electrodes and a size of a molecule of the supporting salt in an ionized state.
