<P>PROBLEM TO BE SOLVED: To provide a stacked cell in which an electrolyte distribution in the stacking direction of a stacked electrode body can be effectively uniformed. <P>SOLUTION: A stacked cell includes a stacked electrode body 10 comprising a plurality sheets of positive electrode plates 1 and a plurality sheets of negative electrode plates 2 which are alternately stacked via a separator. In the stacked cell, the separators for each pair adjacent in the stacking direction are joined at, at least a part of the periphery with each other to form a joined part 4, thereby forming a bag-shaped separator 3, and a rate of a region of the joined part 4 of the bag-shaped separator 3 (the bag-shaped separator 3L with low blocking rate) located at a central region in the stacking direction of the stacked electrode body 10 is smaller than a rate of a region of the joined part 4 of the bag-shaped separator 3 (the bag-shaped separator 3H with high blocking rate) located at both ends in the stacking direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
