A non-aqueous electrolyte usable in rechargeable lithium-ion batteries including a solution of LiPF6/carbonate based electrolytes with low concentrations of LiFOP such that the thermal stability is increased compared to a standard lithium battery. A method of making lithium tetrafluorophospahte (LiF4C2O4, LiFOP) including, reacting PF5 with lithium oxalate, recrystallizing DMC/dichloromethane from a 1 : 1 mixture of to separate LiF4OP from LiPF6 to form a lithium salt. An electric current producing rechargeable Li-ion cell. The rechargeable lithium ion cell includes an anode, a cathode, and a non-aqueous electrolyte comprising a solution of a lithium salt in a non-aqueous organic solvent containing lithium tetrafluorooxalatophosphate (LiPF4(C2O4), LiF4OP).
L'invention concerne un électrolyte non aqueux utilisable dans des batteries au lithium-ion rechargeables comprenant une solution d'électrolytes à base de LiPF6/carbonate avec de faibles concentrations de LiFOP de manière à augmenter la stabilité thermique par rapport à une batterie au lithium classique. L'invention concerne également un procédé de fabrication de lithium tétrafluorophosphate (LiF4C2O4, LiFOP), consistant à faire réagir PF5 avec du lithium oxalate et à recristalliser DMC/dichlorométhane à partir d'un mélange 1:1 pour séparer LiF4OP de LiPF6 afin d'obtenir un sel de lithium. L'invention concerne, de plus, une cellule Li-ion rechargeable produisant un courant électrique. Ladite cellule lithium-ion rechargeable comprend une anode, une cathode et un électrolyte non aqueux contenant une solution de sel de lithium dans un solvant organique non aqueux contenant du lithium tétrafluorooxalatophosphate (LiPF4(C2O4), LiF4OP).
