NOVELTY - A nonaqueous electrolyte secondary battery consists of a positive electrode having positive electrode active material layer (15) containing positive electrode active material formed on the surface of positive electrode collector (11), a negative electrode having negative electrode active material layer (13) containing negative electrode active material and an aqueous binder formed on the surface of negative electrode collector, and electrical power generation element (21) having separator (17) interposed between positive electrode and negative electrode.    USE - Nonaqueous electrolyte secondary battery e.g. lithium-ion secondary battery. Uses include but are not limited to electric vehicle, hybrid electric vehicle, fuel cell vehicle, truck, bus, mobile phone, electric train, and car.    ADVANTAGE - The nonaqueous electrolyte secondary battery has long-term durability, high capacity, excellent output characteristics, and long-term reliability.    DETAILED DESCRIPTION - A nonaqueous electrolyte secondary battery consists of a positive electrode having positive electrode active material layer containing positive electrode active material formed on the surface of positive electrode collector, a negative electrode having negative electrode active material layer containing negative electrode active material and an aqueous binder formed on the surface of negative electrode collector, and electrical power generation element having separator interposed between the positive electrode and negative electrode. The ratio of battery area (projected area of battery including battery exterior component) with respect to the rated capacity is 5 cm2/Ah or more, and the rated capacity is 3 Ah or more. The negative electrode active material contains artificial graphite or coated natural graphite.
