Abstract: A battery includes a stacked electrode body including a plurality of single plate cells and having a positive electrode lead-stacked part and a negative electrode lead-stacked part, the single plate cells each being formed by stacking a positive electrode and a negative electrode with a separator interposed therebetween, the positive electrode lead-stacked part being formed by stacking positive electrode leads of the positive electrodes on top of each other in stacking order of the single plate cells, the negative electrode lead-stacked part being formed by stacking negative electrode leads of the negative electrodes on top of each other in stacking order of the single plate cells; a positive electrode terminal; and a negative electrode terminal.

Abstract: A stack-type nonaqueous electrolyte secondary battery includes an electrode stack. The electrode stack is housed in an exterior body and includes a plurality of positive electrodes, a plurality of negative electrodes, and a separator. The positive electrodes and the negative electrodes are alternately arranged. The separator includes a fanfold portion including a plurality of intervening elements interposed between the positive electrodes and the negative electrodes. The separator includes a wrapper portion at a portion continuous with the fanfold portion. The wrapper portion extends out of the electrode stack and is disposed to cover at least part of a periphery of the electrode stack.
