Title (EN) ELECTRODE ASSEMBLY FOR AN ULTRACAPACITOR
(FR) ENSEMBLE ÉLECTRODE POUR ULTRACONDENSATEUR
Abstract:
(EN) An electrode assembly for an ultracapacitor is provided. The electrode assembly contains a first electrode comprising a first current collector electrically coupled to a first carbonaceous coating, a second electrode comprising a second current collector electrically coupled to a second carbonaceous coating, and a separator positioned between the first electrode and the second electrode. At least a portion of the first current collector projects beyond the first longitudinal edge to define a first projecting portion, wherein the offset ratio of the first projecting portion is from about 0.02 to about 0.3.
(FR) L'invention concerne un ensemble d'électrodes pour un ultracondensateur. L'ensemble d'électrodes contient une première électrode comprenant un premier collecteur de courant couplé électriquement à un premier revêtement carboné, une seconde électrode comprenant un second collecteur de courant couplé électriquement à un second revêtement carboné, et un séparateur positionné entre la première électrode et la seconde électrode. Au moins une partie du premier collecteur de courant dépasse au-delà du premier bord longitudinal pour définir une première partie saillante, le rapport de décalage de la première partie saillante étant d'environ 0,02 à environ 0,3.
