PURPOSE:To facilitate manufacture with high volumetric efficiency. CONSTITUTION:In a sealed storage battery, each cell is stored in a bag-shaped storage unit to form a positive pole grid 2a of a single cell, negative pole grid 3b of a cell adjacent to this grid 2a and connecting unit 4 of both grids 2a, 3b integrally into a continued sheet of synthetic resin film 5. Since necessity for a process of storing a plate group in the bag-shaped storage unit is eliminated and further the connecting unit of the adjacent cells is previously integrally formed into the synthetic resin film, necessity for also a process such as connection between the cells is eliminated. |
