Abstract
A nonaqueous electrolytic solution cell having a negative electrode containing lithium as an active material, a positive electrode, a nonaqueous electrolytic solution consisting of solute and organic solvent, a separator, and an outer can, wherein the organic solvent contains a compound having an S—O bond, and a current collector for the positive electrode and an electrolytic solution-contacting portion on the positive electrode side of the outer can are made of valve metal or alloy thereof is disclosed. The nonaqueous electrolytic solution cell of the present invention is excellent in low-temperature characteristics and long-term stability, and also in cycle characteristics for use as a secondary battery.
