    • Provided is a nonaqueous electrolyte secondary battery. The stacked electrode assembly contains 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. Such positive electrode surfaces where no positive electrode active material layer is formed are opposed, with a separator interposed, to such negative electrode surfaces where no negative electrode active material layer is formed. The separator interposed between the positive electrode active material layers and negative electrode active material layers has a layer containing ceramic. 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.

    • In a nonaqueous electrolyte secondary battery 10 containing a positive electrode 11 having a positive electrode active material capable of intercalating and deintercalating lithium ion; a negative electrode 12 having a negative electrode active material capable of intercalating and deintercalating lithium ion; and a nonaqueous electrolyte, the positive electrode active material contains both lithium cobalt oxide A in which 3 to 5 mol % of magnesium are homogeneously added and lithium cobalt oxide B in which 0.1 to 1 mol % of magnesium is homogeneously added which are mixed in a mixing ratio of lithium cobalt oxide A: lithium cobalt oxide B=2:8 to 8:2. By constituting a nonaqueous electrolyte secondary battery having the above constitution, a nonaqueous electrolyte secondary battery in which the thermal stability and the higher temperature cycle property are remarkably improved without lowering the battery capacity and the load performance.
