Title (EN) OPTIMIZED HYBRID SUPERCAPACITOR
(FR) SUPER-CONDENSATEUR HYBRIDE OPTIMISÉ
(DE) OPTIMIERTER HYBRIDSUPERKONDENSATOR
Abstract:
(EN) The invention relates to a hybrid supercapacitor which comprises electrodes with the following composition: 87.5 to 96.5% by mass of an active material, 2.5 to 7.5% by mass of a conductive additive and 1 to 5% by mass of a binder, wherein the active material of a positive electrode is a mixture of a) 30 to 40% by mass of LiMn2O4 (LMO) and b) 60 to 70% by mass of activated carbon; and wherein the active material of a negative electrode is a mixture of a) 20 to 30% by mass of Li4Ti5O12 (LTO) and b) 70 to 80% by mass of activated carbon. The ratio of the active mass of the negative electrode to the positive electrode lies in the range from 0.4 to 1.2.
(FR) L'invention concerne un super-condensateur hybride qui comprend des électrodes ayant la composition suivante : 87,5 à 96,5 % de masse d’un matériau actif, 2,5 à 7,5 % de masse d’un additif conducteur et 1 à 5 % de masse d’un agent liant. Le matériau actif d’une électrode positive est un mélange d'a) 30 à 40 % de masse de LiMn2O4 (LMO) et b) 60 à 70 % de masse de carbone actif tandis que le matériau actif d’une électrode négative est un mélange de a) 20 à 30 % de masse Li4Ti5O12 (LTO) et b) 70 à 80 % de masse de carbone actif. Le rapport de la masse active de l’électrode négative sur celle de l’électrode positive est dans une plage de 0,4 à 1,2.
(DE) Die Erfindung betrifft einen Hybridsuperkondensator, der Elektroden mit folgender Zusammensetzung umfasst: 87,5 bis 96,5 Masse% eines aktiven Materials, 2,5 bis 7,5 Masse% eines Leitzusatzes, und 1 bis 5 Masse% eines Bindemittels, wobei das Aktivmaterial einer positiven Elektrode ein Gemisch ist aus a) 30 bis 40 Masse% LiMn2O4 (LMO) und b) 60 bis 70 Masse% Aktivkohle; und wobei das Aktivmaterial einer negativen Elektrode ein Gemisch ist aus a) 20 bis 30 Masse% Li4Ti5O12 (LTO) und b) 70 bis 80 Masse% Aktivkohle. Das Verhältnis der Aktivmasse von negativer Elektrode zu positiver Elektrode liegt in einem Bereich von 0,4 bis 1,2.
