ELECTROCHEMICAL DEVICE AND NONAQUEOUS ELECTROLYTE SOLUTION FOR ELECTROCHEMCIAL DEVICE |
摘要 |
The present invention aims to provide an electrochemical device excellent in high temperature storage characteristics and cycling characteristics at high voltages, and a nonaqueous electrolyte for the electrochemical device. The present invention relates to an electrochemical device including: a positive electrode; a negative electrode; and a nonaqueous electrolyte containing a nonaqueous solvent and an electrolyte salt, wherein the nonaqueous solvent contains a fluorinated linear carbonate represented by the formula (1): RfOCOOR(1) (wherein Rf represents a C1-4 fluorinated alkyl group and R represents a C1-4 alkyl group), and further contains following compounds of (I) to (III) in a total amount of not more than 5000 ppm relative to the fluorinated linear carbonate: (I) a compound represented by the formula (2) RfOH(2) (wherein Rf is defined as above); (II) a compound represented by the formula (3) ROH(3) (wherein R is defined as above); and (III) a compound represented by the formula (4) ROCOCl(4) (wherein R is defined as above). |
