Activated porous carbon massive electrodes, process of making them, and use thereof in an electrical double layer capacitor.

摘要

Solid electrodes made from activated porous carbon, their method of manufacture and their use in a capacitor with double electrical layer. The capacitor of the invention includes a sealed envelope (4) enclosing at least one unitary element (2a, 2b) including two electrodes (6a, 8a, 6b, 8b) impregnated with an electrolyte (21), and which consist of activated solid porous carbon and are covered on one of their faces (7a, 13a, 7b, 13b) with a thin continuous electrically conducting layer (16a, 18a, 16b, 18b), the other faces (9a, 11a, 9b, 11b) being provided with blind holes (12) facing one another. This capacitor furthermore includes contacts (24, 26) for bringing current to the electrodes.
