Patent ID: 7300723

Claim:
A lithium cell comprising: a positive electrode; a negative electrode; a separator interposed between the positive electrode and the negative electrode; and a nonaqueous electrolyte including a nonaqueous solvent and an electrolytic salt, wherein: the nonaqueous solvent includes: among compounds represented by the following general formula (1), at least one compound having a boiling point of 200° C. or higher; and among compounds represented by the following general formula (1), at least one compound having a boiling point of lower than 200° C.; and a 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; the compound having a boiling point of lower than 200° C. includes 1,2-dimethoxyethane; and a volume ratio of the compound having a boiling point of lower than 200° C. is 50 to 60 percent of a total volume at 23° C. of the compounds represented by the following general formula (1), X—(O—C 2 H 4 )n-O—Y (1) (where X and Y are independently an alkyl group (number of carbons: 1-4), and n is 1-5).
