ABSTRACT:
The present invention provides a cell that does not impair heat resistant safety and electrochemical characteristics such as a discharge characteristic, and enhances long-period reliability. In the cell of the present invention, a nonaqueous solvent has, among compounds represented by the following general formula (1), at least one solvent having a boiling point of 200° C. or higher, and has, among compounds represented by the following general formula (1), at least one solvent having a boiling point of lower than 200° C.; and the total volume ratio at 23° C. of the compounds represented by the following general formula (1) is 95 to 100 percent of the nonaqueous solvent,in-line-formulae description="In-line Formulae" end="lead"?X—(O—C2H4)n-O—Y (1)in-line-formulae description="In-line Formulae" end="tail"?(where X and Y are independently an alkyl group (number of carbons: 1-4), and n is 1-5).
