Abstract
A nonaqueous electrolyte battery comprising a positive electrode, a negative electrode having lithium as an active material, a nonaqueous electrolyte comprising a solute and a solvent, and a separator. The solvent is a mixed solvent consisting essentially of 5 to 50% by volume of cyclic carbonate, 5 to 50% by volume of chain carbonate and 40 to 80% by volume of ether. The mixed solvent of a specific composition is less likely to cause undesirable surface layer formation on the negative electrode so that the electric resistance of the interface between the negative electrode and nonaqueous electrolyte is kept small. The nonaqueous electrolyte battery of the invention can therefore deliver a large amount of current and provide a high discharge capacity at low temperatures.
