TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: In the battery: a portion where a surface on which no positive electrode active material layer is formed and a surface on which no negative electrode active material layer is formed are opposed with a separator interposed, is located at one, or both (preferred) of the outermost portions, and is also formed in a central region, in the stacking direction, of the stacked electrode assembly; at the outermost portions, in the stacking direction, of the stacked electrode assembly, an electrode plate of one polarity with an active material layer formed on one side only of the substrate, and an electrode plate of the other polarity with no active material layer formed on both sides of the substrate, are stacked, with a separator interposed, in the order from inward to outward; at the outermost portions, in the stacking direction, of the stacked electrode assembly, an electrode plate of one polarity with an active material layer formed on one side only of the substrate, an electrode plate of the other polarity with no active material layer formed on both sides of the substrate, and an electrode of the one polarity with no active material layer formed on both sides of the substrate, are stacked, with separators interposed, in the order from inward to outward; and the active material layer of the electrode plate of the one polarity with an active material layer formed on one side only of the substrate is opposed, with a separator interposed, to an active material layer formed on an electrode plate of the other polarity that is located inward in the stacking direction of the stacked electrode assembly. The ceramic layer-containing separator: is a microporous film made of polyolefin; is provided with a layer containing ceramic and binder on one or both faces of a microporous film made of polyolefin, where the ceramic is alumina, silica or titania; and is an item in which a layer composed of ceramic and binder is provided on one side only of a microporous film of polyolefin and the layer composed of ceramic and binder is disposed so as to be opposed to the negative electrode active material layers of the negative electrode plates. In the battery: the outer covering is a laminate outer covering; and the nonaqueous electrolyte secondary battery has a capacity of not less than 10 Ah and a thickness of not more than 15 mm. The stacked electrode assembly includes: greater than or equal to 10 positive electrode plates with positive electrode active material layers formed on both sides of the positive electrode substrate; and greater than or equal to 10 negative electrode plates with negative electrode active material layers formed on both sides of the negative electrode substrate.
