<P>PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery in which rapid exothermic reaction, firing, burst, and the like, are prevented even when short circuit occurs due to nailing or collapse. <P>SOLUTION: In a lamination electrode body, a positive electrode plate where a positive electrode active material layer is not formed on at least one side of a positive electrode core, and a negative electrode plate where a negative electrode active material layer is not formed on at least one side of a negative electrode core are included, and the surface where the positive electrode active material layer is not formed and the surface where the negative electrode active material layer is not formed face each other with a separator interposed therebetween. The separator interposed between the positive electrode active material layer and the negative electrode active material layer has a layer containing ceramic, and the separator interposed between the surface where the positive electrode active material layer is not formed and the surface where the negative electrode active material layer is not formed does not have a layer containing ceramic in the nonaqueous secondary battery. <P>COPYRIGHT: (C)2013,JPO&INPIT |
