The present invention relates to electrical engineering and can find application for making devices accumulating electric energy. The invention has for its object to improve the electrical characteristics of double- layer capacitors. To this aim, use is made of a nickel-oxide electrode in pair with an electrode made of a fibrous carbonic material, as well as of an aqueous- alkaline or aqueous-carbonate electrolyte. To obtain a power capacity of the capacitor, the carbonic material one of the electrodes is made from is nickel- copper-plated.

Cette invention se rapporte au domaine de l'électrotechnique et peut être utilisée dans la fabrication de dispositifs de stockage d'énergie électrique. Cette invention a pour but d'améliorer les caractéristiques électriques de condensateurs. A cette fin, on fait appel à une électrode oxyde-nickel appariée à une électrode faite d'un matériau de carbone fibreux, ainsi qu'à un électrolyte aqueux alcalin ou carbonate. Afin d'augmenter la puissance, le matériau à base de carbone utilisé dans la préparation de l'une des électrodes est plaqué avec du nickel ou du cuivre.
