Title (EN) ELECTROLYTES CONTAINING SIX MEMBERED RING CYCLIC SULFATES
(FR) ÉLECTROLYTES CONTENANT DES SULFATES CYCLIQUES À NOYAU À SIX CHAÎNONS
Abstract:
(EN) Disclosed herein are electrolyte compositions comprising at least one electrolyte component comprising a cyclic carbonate, such as a fluoroethylene carbonate, and at least one additive comprising a 6-member ring heterocyclic sulfate, such as a 1,3 propylene sulfate. The disclosed electrolyte compositions can comprise additional electrolyte components, such as fluorinated acyclic carboxylic acid esters, and additional additives, such as lithium boron compounds, and cyclic carboxylic acid anhydrides, such as maleic anhydride. The improved battery performances, which include high temperature cycling conditions and/or room temperature stability, make these electrolyte compositions useful in electrochemical cells, such as lithium ion batteries.

(FR) L'invention concerne des compositions d'électrolyte comprenant au moins un composant d'électrolyte comprenant un carbonate cyclique, tel qu'un carbonate de fluoroéthylène, et au moins un additif comprenant un sulfate hétérocyclique à noyau à 6 chaînons, tel qu'un 1,3-propylène-sulfate. Les compositions d'électrolyte de l'invention peuvent comprendre des composants d'électrolyte supplémentaires, tels que des esters d'acide carboxylique acyclique fluoré, et des additifs supplémentaires, tels que des composés de lithium-bore, et des anhydrides d'acide carboxylique cyclique, tels que l'anhydride maléique. Les performances améliorées de la batterie, qui comprennent des conditions de cyclage à haute température et/ou une stabilité à température ambiante, rendent ces compositions d'électrolyte utiles dans des cellules électrochimiques, telles que des batteries au lithium-ion.
