Abstract:
     In the double-layer capacitor, at least on the inner face of anodic metal container an aluminium layer is formed. An electrochemical stable anodic oxidation film is formed on the aluminium layer according to additional voltage. This invention cleverly uses that performance of the oxidation film which its resistance is such low extent that it is nothing wrong in use, therefore the voltage-resistant double-layer capacitor above 3V is obtained.
