Abstract
A high-capacity nonaqueous electrolyte secondary battery having good load characteristics is provided. The nonaqueous electrolyte secondary battery includes a positive electrode containing a positive electrode active material, a negative electrode, and a nonaqueous electrolyte. The positive electrode contains the active material composed of a lithium transition metal oxide and a positive electrode additive composed of an oxide that contains Li and at least two elements other than Li and oxygen and has an antifluorite structure. The nonaqueous electrolyte secondary battery obtained is charged until the potential of the positive electrode is 4.0 V or higher and 4.65 V or lower (vs. Li/Li).
