NOVELTY - A nonaqueous secondary battery consists of electrode component on which positive electrode (1) and negative electrode (2) are laminated through a separator (3), and nonaqueous electrolyte. The positive electrode comprises positive electrode active material which can occlude and desorb lithium ion in one or both surfaces of electrical power collector, and positive mix layer containing binder. The negative electrode comprises negative electrode active material formed using alloy-based material containing compound of lithium, and negative mix layer containing binder.    USE - Nonaqueous secondary battery e.g. lithium ion secondary battery. Uses include but are not limited to mobile telephone, notebook computer, motor vehicle, bicycle and electric power storage.    ADVANTAGE - The nonaqueous secondary battery has excellent charging/discharging cycling characteristics and storage stability.    DETAILED DESCRIPTION - A nonaqueous secondary battery consists of electrode component on which positive electrode and negative electrode are laminated through a separator, and nonaqueous electrolyte. The volume energy density of nonaqueous secondary battery is 600 Wh/L or more. The positive electrode comprises positive electrode active material which can occlude and desorb lithium ion in one or both surfaces of electrical power collector, and positive mix layer containing binder. The negative electrode comprises negative electrode active material formed using alloy-based material containing compound of lithium or element capable of alloying with lithium in one or both surfaces of an electrical power collector, and negative mix layer containing binder. The current density (A/B) of nonaqueous battery is 4 or more, which is the ratio of opposing area (A) of the positive mix layer of positive electrode, and area (B) of negative mix layer of negative electrode. The binder present in the positive mix layer comprises polymer or copolymer having structural unit derived from monomer(s) chosen from tetrafluoroethylene and hexafluoropropylene. The binder present in the negative mix layer comprises copolymer having structural unit derived from monomer(s) chosen from tetrafluoroethylene and hexafluoropropylene. The ratio (t) of the alloy-based material in negative electrode active material of nonaqueous electrolyte battery is 0.5-20, and satisfies the relation: (D'x 1.07+Ex (1+tx 0.024)+F'x 0.98)x 1.86 less than or equal to C' less than or equal to (D'x 1.07+Ex (1+tx 0.024)+F'x 0.98)x 2.14, where C' is volume (cm3) of nonaqueous electrolyte battery, D' is void volume (cm3) of positive mix layer, void volume (cm3) of negative mix layer and F' is void volume (cm3) of separator.
