Embodiment 1
[0010] The present embodiment provides a kind of explosion-proof lithium-ion battery electrolyte, comprises LiPF Electrolyte, comprises following solvent and adds additive:
[0011] Trifluoropropylene carbonate and chloroethylene carbonate and ethylene carbonate and propylene carbonate mixed solution, ethyl methanesulfonate additive, trimethyl phosphite additive, phosphazene additive.
[0012] The weight of described propylene trifluorocarbonate and chloroethylene carbonate is 32% of solvent plus additive weight. The weight of described ethylene carbonate and propylene carbonate is solvent plus 40% of additive weight. The weight of the ethyl methanesulfonate additive is the solvent plus 10% of the weight of the additive. The weight of the trimethyl phosphite additive is the solvent plus 10% of the weight of the additive. The weight of the phosphazene additive is 8% of the weight of the solvent plus the additive.
