摘要： In an electrochemical cell using a conventional thermally resistant container, there is a problem in that, when it is used at a relatively high voltage, for example, around 3 V, a metal of a collector is dissolved and characteristics thereof are extremely deteriorated. In order to prevent a positive electrode current collector from being dissolved even at a high potential, a surface of the positive electrode current collector is covered by a valve metal or carbon such that the positive electrode current collector and a positive electrode do not come in contact with each other. Therefore, in the electrochemical cell according to the invention, the positive electrode current collector is prevented from being dissolved.

摘要： An electrical double layer capacitor has an electrolyte included 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. When the electrical double layer capacitor is charged at 3.3 V for 24 hours, a charged current after 24 hours is in the range of from about 5 &mgr;A/cm2 to about 22 &mgr;A/cm2 per unit area of the polarizing electrodes.
