Abstract (en)
[origin: WO2019122314A1] An electrolyte composition for a lithium-ion electrochemical element, comprising: - at least one lithium tetrafluoride or hexafluoride salt, - the salts of lithium bis(fluorosulfonyl)imide LiFSI, - vinylene carbonate, - ethylene sulfate, - at least one organic solvent chosen from the group consisting of cyclic or linear carbonates, cyclic or linear esters, cyclic or linear ethers and a mixture of same. The use of this composition in a lithium-ion electrochemical element increases the service life of the element, in particular under low and high temperature cycling conditions.
