Abstract
A plurality of cells each encased in prismatic cell cases having short lateral walls and long lateral walls are arranged side by side, with adjacent short lateral walls being integral with each other, thereby constituting an integral battery case. The upper open ends of the plurality of prismatic cell cases are integrally closed by a single lid member. Each of the cells accommodates therein a group of electrodes stacked alternately upon one another parallel to the long lateral walls of the cell cases with intervening separators therebetween. Neighboring cells are connected in series at their abutting lateral opposite ends with each other.
