を図ることができる。According to the present invention, a plurality of intersecting thick bones are provided in the frame bones of each lattice constituting the lattice unit at predetermined intervals in a direction intersecting with the large bones. In the case of filling each lattice body of the above with the active material paste, the attempt to escape the active material paste toward the outside is blocked by the respective thick bones and the respective crossed thick bones, and the diagonally crossed thick bones are used to activate the active material paste. The material pastes are sequentially moved inward, so that the variation of the filling thickness depending on the position can be suppressed, and the thickness of the electrode plate can be made uniform.

ことができる。In particular, in the present invention, the angle θ formed by each crossed bone with respect to each bone is increased stepwise each time it crosses over each bone and approaches the adjacent lattice body. The resistance acting on the active material paste at the time of filling becomes larger toward the outside, so that the active material paste is less likely to escape toward the outside, becomes easier to flow inward, and has a width so that the filling thickness becomes uniform. The leveling in the direction can be effectively performed.

In the case of filling, the action of blocking the active material paste from escaping toward the outside can be further promoted by these crossed fine bones, and the action of these crossed thick bones moving the active material paste inward is further enhanced. It can be promoted, the variation due to the position of the filling thickness can be further suppressed, and the thickness of the electrode plate can be made more uniform.

る。When the electrode group is formed by using the paste type electrode plate in which the variation of the thickness due to the position of the active material layer is suppressed, the electrode plate is formed in the battery case between the upper and lower parts of the electrode plate group. There is no big difference in the group pressurization applied to the group, and it is possible to avoid adversely affecting the capacity and life of the storage battery.
