Summary:A high-voltage non-aqueous electrolyte and a lithium-ion secondary battery, relating to the technical field of lithium-ion batteries. Methyl trifluoroethyl carbonate and a first additive are added into an electrolyte, such that a synergistic effect can be achieved when the methyl trifluoroethyl carbonate and the first additive are used in combination, and the cycle and low-temperature performance of an ion battery at high voltage can be obviously improved. L'invention concerne un électrolyte non aqueux à haute tension et une batterie secondaire au lithium-ion, se rapportant au domaine technique des batteries au lithium-ion. Du carbonate de trifluoroéthyle méthyle et un premier additif sont ajoutés dans un électrolyte, de telle sorte qu'un effet synergique peut être obtenu lorsque le carbonate de trifluoroéthyle méthyle et le premier additif sont utilisés en combinaison, et le cycle et les performances à basse température d'une batterie ionique à haute tension peuvent être évidemment améliorés. 一种高电压非水电解液及锂离子二
