NOVELTY - Nonaqueous electrolyte secondary battery comprises: a stacked electrode assembly (10) in which positive electrode plates with positive electrode active material layers formed on both sides of a positive electrode substrate, and negative electrode plates with negative electrode active material layers formed on both sides of a negative electrode substrate are stacked with separators (11a) interposed; nonaqueous electrolyte; and an outer covering housing the stacked electrode assembly and the nonaqueous electrolyte.    USE - Used as a nonaqueous electrolyte secondary battery.    ADVANTAGE - The nonaqueous electrolyte secondary battery: does not emit smoke, ignite or burst, even if short-circuited by being pierced by a nail or crushed, and thus has improved safety; and has high capacity, superior cycling characteristics and energy density.    DETAILED DESCRIPTION - Nonaqueous electrolyte secondary battery comprises: a stacked electrode assembly (10) in which positive electrode plates with positive electrode active material layers formed on both sides of a positive electrode substrate, and negative electrode plates with negative electrode active material layers formed on both sides of a negative electrode substrate are stacked with separators (11a) interposed; nonaqueous electrolyte; and an outer covering housing the stacked electrode assembly and the nonaqueous electrolyte. The stacked electrode assembly comprises positive electrode plates in which no positive electrode active material layer is formed on at least one side of the positive electrode substrate, and negative electrode plates in which no negative electrode active material layer is formed on at least one side of the negative electrode substrate, where such positive electrode surfaces with no positive electrode active material layer formed on them are opposed, with a separator interposed, to such negative electrode surfaces with no negative electrode active material layer formed on them. The separator interposed between the positive electrode active material layers and negative electrode active material layers has a layer containing ceramic, and the separator interposed between the surfaces where no positive electrode active material layer is formed and the surfaces where no negative electrode active material layer is formed has no layer containing ceramic.
