Abstract
(EN)
A non-aqueous electrolyte for a lithium-ion battery, and a lithium-ion battery comprising said non-aqueous electrolyte, the electrolyte comprising: a solvent, lithium salt and, as shown in structural formula I, an unsaturated phosphite ester compound: (I), wherein R1 comprises an alkenyl having between 2 and 5 carbon atoms or an alkynyl having between 2 and 5 carbon atoms, R2 comprises a fluoroalkyl or cyano having between 1 and 4 carbon atoms, and R3 comprises an alkyl having between 1 and 4 carbon atoms, an aryl having between 6 and 10 carbon atoms, an alkenyl having between 2 and 5 carbon atoms, an alkynyl having between 2 and 5 carbon atoms, or a fluoroalkyl or cyano having between 1 and 5 carbon atoms. Using an unsaturated phosphite ester additive in a lithium-ion battery electrolyte causes the problem of increased electrolyte chrominance, whereas no discoloration occurs in the process of storing the above lithium-ion battery non-aqueous electrolyte.

L'invention concerne un électrolyte non aqueux pour une batterie au lithium-ion, et une batterie au lithium-ion comprenant ledit électrolyte non aqueux, l'électrolyte comprenant : un solvant, un sel de lithium et, comme représenté dans la formule structurale I, un composé d'ester de phosphite insaturé : (I), dans laquelle R1 comprend un alcényle ayant entre 2 et 5 atomes de carbone ou un alcynyle ayant entre 2 et 5 atomes de carbone, R2 comprend un fluoroalkyle ou cyano ayant entre 1 et 4 atomes de carbone, et R3 comprend un alkyle ayant entre 1 et 4 atomes de carbone, un aryle ayant entre 6 et 10 atomes de carbone, un alcényle ayant entre 2 et 5 atomes de carbone, un alcynyle ayant entre 2 et 5 atomes de carbone, ou un fluoroalkyle ou cyano ayant entre 1 et 5 atomes de carbone. L'utilisation d'un additif d'ester de phosphite insaturé dans un électrolyte de batterie au lithium-ion permet de résoudre le problème de la chrominance d'électrolyte accrue, tandis qu'aucune décoloration n'a lieu dans le processus de stockage de l'électrolyte non aqueux de batterie au lithium-ion ci-dessus.
