Method for stabilizing content of moisture, HF and color and luster in lithium-ion functional electrolyte

The invention discloses a method for stabilizing the content of moisture, HF and color and luster in a lithium-ion functional electrolyte, and belongs to the technical field of lithium-ion functional electrolyte. According to the technical scheme, the method for stabilizing the content of the moisture, the HF and the color and luster in the lithium-ion functional electrolyte comprises the steps that a carbimide compound is added into the lithium-ion functional electrolyte, and the carbimide compound accounts for 0.07%-1% of the total weight of the lithium-ion functional electrolyte. By adding a certain amount of carbimide compound into the lithium-ion functional electrolyte, the content of the moisture, the HF and the color and luster in the lithium-ion functional electrolyte can be stabilized, and the quality of the lithium-ion functional electrolyte is effectively improved; in addition, the dosage of the carbimide compound is low, and the effect is good.
