Title
(EN) ULTRACAPACITOR FOR USE AT HIGH TEMPERATURES
(FR) ULTRACONDENSATEUR DESTINÉ À ÊTRE UTILISÉ À DES TEMPÉRATURES ÉLEVÉES
Abstract
(EN)
An ultracapacitor that is in contact with a hot atmosphere having a temperature of about 80C or more is provided. The ultracapacitor contains a first electrode, second electrode, separator, nonaqueous electrolyte, and housing is provided. The first electrode comprises a first current collector electrically coupled to a first carbonaceous coating and the second electrode comprises a second current collector electrically coupled to a second carbonaceous coating. The capacitor exhibits a capacitance value within the hot atmosphere of about 6 Farads per cubic centimeter or more as determined at a frequency of 120 Hz and without an applied voltage.

L'invention porte sur un ultracondensateur qui est en contact avec une atmosphère chaude ayant une température d'environ 80 °C ou plus. L'ultrarcondensateur contient une première électrode, une seconde électrode, un séparateur, un électrolyte non aqueux et un boîtier. La première électrode comprend un premier collecteur de courant couplé électriquement à un premier revêtement carboné et la seconde électrode comprend un second collecteur de courant couplé électriquement à un second revêtement carboné. Le condensateur présente une valeur de capacité dans l'atmosphère chaude d'environ 6 farads par centimètre cube ou plus, déterminée à une fréquence de 120 Hz et sans tension appliquée.
