NOVELTY - A nonaqueous electrolyte secondary battery (10) has battery case (15) having electrode component (50) containing positive electrode (64) and negative electrode (84), and nonaqueous electrolyte. Positive electrode has positive electrode compound material layer (66) containing positive electrode active material. Negative electrode has negative electrode compound material layer (86) containing negative electrode active material. Nonaqueous electrolyte is calcium oxalate.    USE - Nonaqueous electrolyte secondary battery e.g. lithium ion secondary battery is used for assembly (claimed) used as driving power supply mounted in vehicles e.g. hybrid vehicle, electric vehicle and fuel motor vehicle.    ADVANTAGE - The nonaqueous electrolyte secondary battery has excellent battery performance. The generation of sufficient gas volume is ensured at the time of pressure rise within the battery case of nonaqueous electrolyte secondary battery, while achieving reduction of battery resistance.    DETAILED DESCRIPTION - A nonaqueous electrolyte secondary battery has a battery case in which an electrode component having a positive electrode and a negative electrode, and a nonaqueous electrolyte are accommodated. The positive electrode has positive electrode compound material layer containing positive electrode active material. The negative electrode has negative electrode compound material layer containing negative electrode active material. At least one of positive electrode compound material layer and negative electrode compound material layer contain calcium salt of carboxymethylcellulose. A film containing phosphorus and/or boron, is formed in the surface of negative electrode active material. The nonaqueous electrolyte is calcium oxalate. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of nonaqueous electrolyte secondary battery; and    (2) nonaqueous electrolyte secondary battery assembly (70).
