Abstract
The present invention provides a nonaqueous electrolyte secondary battery characterized by a significantly smaller amount of gas formation and excellent cycle stability exhibited during cycle testing even when a titanium compound is used for a negative electrode. A nonaqueous electrolyte secondary battery is structured to have a casing, encapsulating a positive electrode, nonaqueous electrolyte, and a negative electrode facing the positive electrode across a separator. The negative electrode contains a titanium compound as a negative-electrode active material,
