Title
(EN) NON-AQUEOUS ELECTROLYTES FOR LITHIUM ION BATTERIES
(FR) ELECTROLYTES NON AQUEUX DESTINES A DES BATTERIES AU LITHIUM-ION
Abstract
(EN)
The present invention is generally related to electrolytes containing anion receptor additives to enhance the power capability of lithium-ion batteries. The anion receptor of the present invention is a Lewis acid that can help to dissolve LiF in the passivation films of lithium-ion batteries. Accordingly, one aspect the invention provides electrolytes comprising a lithium salt; a polar aprotic solvent; and an anion receptor additive; and wherein the electrolyte solution is substantially non-aqueous. Further there are provided electrochemical devices employing the electrolyte and methods of making the electrolyte.

L'invention concerne, d'une manière générale, des électrolytes renfermant des additifs de récepteurs anioniques aux fins d'amélioration de la capacité de puissance de batteries au lithium-ion. Le récepteur anionique selon l'invention est un acide de Lewis pouvant contribuer à la dissolution de LiF dans les films de passivation de batteries au lithium-ion. Un mode de réalisation de l'invention concerne des électrolytes comprenant un sel de lithium; un solvant aprotique polaire; et un additif de récepteurs anioniques; et la solution d'électrolytes étant sensiblement non aqueuse. De plus, l'invention concerne des dispositifs électrochimiques mettant en oeuvre l'électrolyte et des procédés de fabrication de celui-ci.
