The present invention relates to a double electric layer capacitor. The capacitor of the invention has a non-polarizable (positive) electrode (1), a polarizable (negative) electrode (2), and an electrolyte (5). According to the invention, the non-polarizable electrode (1) is made of a lead-containing material, while the polarizable electrode (2) is made of a material containing carbon. In a preferred embodiment, the electrodes (1, 2) and the electrolyte (5) are disposed in a container (6) and a separator (4) is provided between the electrodes (1, 2). ŕ |
