A kind of flame-retardant electrolyte of lithium-ion-power cell

The invention discloses a kind of flame-retardant electrolytes of lithium-ion-power cell, including electrolyte lithium salt, organic solvent, film for additive, flame-retardant additive.It has used di-oxalate lithium borate as electrolyte lithium salt used in electrolyte in electrolyte of the invention, the thermal stability of electrolyte can be improved；Meanwhile it being added to flame-retardant additive in the electrolytic solution, the flame retardant property of electrolyte can be further improved, the safety of electrolyte is indirectly improved, can preferably meet requirement of the electric car to the temperature performance of electrolyte.
