Beschreibung
Zusammenfassung:	The present invention relates to an electric double layer capacitor including at least one pair of polarizable electrodes connected to current collectors, a separator made of ion-permeable but electron-insulating material interposed between the electrodes in each pair of electrodes, and a liquid electrolyte. According to the invention the electrodes include a layer of carbon particles having a narrow distribution of nanopores therein, the pore sizes of the nanopores being adapted to fit the ion sizes of the electrolyte. The invention also relates to a method of manufacturing such a supercapacitor. L'invention concerne un condensateur électrique à double couche comportant au moins deux électrodes polarisables reliées à des collecteurs de courant, un séparateur fait avec un matériau perméable aux ions mais non conducteur d'électrons intercalé entre chaque deux électrodes, et enfin, un électrolyte liquide. Selon l'invention, ces électrodes comportent une couche de particules de carbone pourvue de nanopores à distribution étroite, la taille des nanopores étant adaptée à celle des ions de l'électrolyte. Par ailleurs, l'invention concerne un procédé de fabrication de ce type de supercondensateur.
