摘要： The disclosure relates to a fluorine-substituted propylene carbonate-based electrolytic solution and a lithium-ion battery, particularly to a fluorine-substituted propylene carbonate-based electrolytic solution comprising fluorine-substituted propylene carbonate as a primary solvent and a co-solvent, wherein the fluorine-substituted propylene carbonate comprises 50-80 vol.%, and the co-solvent comprises 20-50 vol.%, based on the volume of the electrolytic solution for a lithium-ion battery. The advantages of the disclosure include: the electrolytic solution has a liquid range of over 300°C, resistance to high voltage, and low flammability; the fluorine-substituted propylene carbonate shows excellent film-forming effect on the surfaces of the positive and negative electrodes of the battery, thereby increasing the compatibility between the electrolytic solution and the positive and negative electrodes of the battery; the lithium-ion battery manufactured using this electrolytic solution has good safety, a broad operating temperature range, a high operating voltage and superior recyclability, and thus a promising prospect is expected for use in development of highly safe lithium-ion batteries having high specific energy and a wide temperature range for power supply and energy storage.

摘要： The invention relates to a method of preparing lithium bis(fluorosulfonyl)imide, comprising: reacting lithium bis(chlorosulfonyl)imide with an alkali metal fluoride used as a fluorinating agent in a solvent of saturated alkyl carbonate and/or saturated fluoroalkyl carbonate in the presence of a crownether phase transfer catalyst adaptive to the alkali metal fluoride to obtain lithium bis(fluorosulfonyl)imide. The method of preparing lithium bis(fluorosulfonyl)imide according to the invention possesses a simple process route, and industrial manufacture can be realized easily.
