Abstract:
Disclosed is a nonaqueous electrolyte comprising a nonaqueous solvent which contains ethylene carbonate (EC), propylene carbonate (PC), &ggr;-butyrolactone (BL), and a fourth component, which is a solvent other than the EC, PC and BL, and the mixing ratio x (% by volume) of EC based on the total amount of the nonaqueous solvent falls within a range of between 15 and 50, the mixing ratio y (% by volume) of PC based on the total amount of the nonaqueous solvent falls within a range of between 2 and 35, the mixing ratio z (% by volume) of BL based on the total amount of the nonaqueous solvent falls within a range of between 30 and 85, and the mixing ratio p (% by volume) of the fourth component based on the total amount of the nonaqueous solvent is larger than 0 and is not larger than 5.
