Title (EN) NONAQUEOUS ELECTROLYTE FOR AN ULTRACAPACITOR
(FR) ÉLECTROLYTE NON AQUEUX POUR SUPERCONDENSATEUR
Abstract:
(EN) An ultracapacitor that 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 nonaqueous electrolyte is in ionic contact with the first electrode and the second electrode, wherein the nonaqueous electrolyte contains an ionic liquid that is dissolved in a nonaqueous solvent at a concentration of about 1.0 mole per liter or more. The nonaqueous solvent has a boiling temperature of about 150°C or more.
(FR) L'invention porte sur un supercondensateur qui 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. L'électrolyte non aqueux est en contact ionique avec la première électrode et la seconde électrode, l'électrolyte non aqueux contenant un liquide ionique qui est dissous dans un solvant non aqueux à une concentration supérieure ou égale à environ 1,0 mole par litre. Le solvant non aqueux a une température d'ébullition supérieure ou égale à environ 150 °C.
