Abstract:
1. A module battery, comprising: a plurality of cells including an electrode tab and a cell body having a power generating element hermetically sealed in a package film, the power generating element being formed by stacking electrode plates, the electrode tab being connected to the power generating element and being drawn outward from an edge of the package film, wherein the module battery is configured such that the plurality of the cells are stacked on one another, and the electrode tabs of the cells adjacent to each other in a stacking direction are interconnected, wherein the electrode tabs of the cells form an approximate L-shape and the electrode tabs have a bent portion which is a portion extending from a folding line in the stacking direction of the cells, wherein the bent portions of the cells adjacent to each other in the stacking direction are at least partially overlapped with each other so as to be interconnected, and wherein the cells are mounted and held on respective frame-shaped cell holders, and the electrode tabs of the cells are exposed from between the cell holders adjacent to each other in the stacking direction.
