摘要： Disclosed is a method for purifying a difluorophosphate, the method including mixing a difluorophosphate containing an impurity with at least one treatment agent selected from the group consisting of carbonates, hydroxides, and halides of alkali metals or alkali earth metals and amines to isolate the impurity. It is preferable that the method further include filtering off, by filtration, a salt or a complex that has been formed by allowing the impurity to be mixed with the treatment agent. Preferably, a carbonate, a hydroxide, or a halide of an alkali metal is used as the treatment agent, and more preferably a carbonate, a hydroxide, or a halide of lithium is used as the treatment agent.

摘要： The purpose of the present invention is to provide a method for easily producing a difluorophosphate using only low-cost starting materials without requiring cumbersome operations. According to the present invention, at least one salt selected from the group consisting of halides, carbonates, borates, phosphates, hydroxides and oxides of an alkali metal, an alkaline earth metal or an onium, at least one phosphorus compound selected from the group consisting of oxychlorides and chlorides of phosphorus, water and hydrogen fluoride are reacted. The above-mentioned purpose is achieved preferably using, as hydrogen fluoride, one substance selected from the group consisting of hydrogen fluoride anhydride, a mixed solution of hydrogen fluoride anhydride and an organic solvent and a mixed gas of hydrogen fluoride anhydride and an inert gas, as a salt used in the reaction, at least one substance selected from the group consisting of halides and carbonates of an alkali metal, and as a phosphorus compound, phosphoryl chloride.

摘要： Provided are, a nonaqueous electrolytic solution for secondary batteries that has excellent oxidation resistance, prevents reaction between itself and electrodes, is resistant to decomposition under high-voltage conditions, and is capable of reducing the capacity decrease of and gas evolution in a secondary battery; and a nonaqueous electrolyte secondary battery using the nonaqueous electrolytic solution. The nonaqueous electrolytic solution for secondary batteries comprises a nonaqueous solvent comprising an ester having 3,3,3-trifluoropropionate groups represented by the following formula 1: (wherein n represents an integer of 1 to 20.) a fluorinated cyclic carbonate that is 4-fluoroethylene carbonate (FEC) or a derivative thereof, and at least one selected from a cyclic carbonate, a chain carbonate, and a fluorinated chain carboxylic acid ester; and a lithium salt as an electrolyte.
