摘要：
The invention provides an electrolyte solution that can hardly increase the resistance of an electrochemical device such as a lithium ion secondary battery even after the electrochemical device is stored at high temperature in comparison with that before the storage. The electrolyte solution contains tris(trimethylsilyl) phosphite and at least one fluorinated saturated cyclic carbonate (1) selected from the group consisting of pentafluoropropylethylene carbonate and heptafluoroisobutylethylene carbonate.
