<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrolyte for an electrochemical device, having a wide potential window, resulting in the electrolyte being hard to deposit and having higher specific conductivity. <P>SOLUTION: The electrolyte for the electrochemical device contains an organic solvent and lithium salt or sodium salt dissolved therein, the organic solvent containing at least one nitrile compound from among a chain saturated hydrocarbon dinitrile compound having nitrile groups bonded to both terminals of a chain saturated hydrocarbon compound; a chain cyanoether compound having nitrile groups, bonded to at least one terminal of a chain ether compound; and a cyanoacetic acid ester, and at least one of cyclic carbonate, cyclic ester and chain carbonate, The method for manufacturing the electrolyte for the electrochemical device includes a mixing step of mixing the organic solvent, having water content of 100 ppm or lower and the lithium salt or the sodium salt having water content of 100 ppm or lower and form a uniform solution. <P>COPYRIGHT: (C)2011,JPO&INPIT |
