Patent

CA 2339627

Novel sulfonylimide and sulfonylmethide compounds are described which are useful as conductive salts. Also described is the use of the above compounds in salt form in battery electrolytes, particular salts having mixed perfluorocarbon and hydrocarbon groups or having all hydrocarbon groups. The above salts are less expensive to produce and still exhibit excellent conductivity and low corrosivity.

L'invention concerne de nouveaux composés sulfonylimides et sulfonylméthides se prêtant à une utilisation en tant que sels conducteurs. Fait aussi l'objet de cette invention l'utilisation des composés précités sous forme de sels dans les électrolytes de piles, ces sels ayant des groupes mélangés perfluorocarbonés et hydrocarbonés ou ayant tous les groupes hydrocarbonés. Ces sels sont moins coûteux pour la production et arborent une excellente conductivité et une faible corrosivité.
