ゼることにより、急激に容量低下を起すものがあった。Conventional technology Clad 2M batteries use a clad type electrode plate in which the active material is covered with a tube made of glass fiber or synthetic resin as the positive electrode plate, and a paste type electrode in which the active material is coated on a lattice body is used as the negative electrode plate. Since a plate is used, both the positive and negative electrode plates are paste-type electrode plates. It is characterized by a longer lifespan than TF ponds. However, it was expensive because it took time and effort to produce the electrode plates. In addition, the active material that softens and falls off the positive electrode plate during use is blown up by gassing during charging, causing a bridge short circuit between the positive and negative electrode plates at the top of the electrode plate group, which can cause a sudden decrease in capacity. there were.

In addition to preventing short circuits in the tube, it also reduces the manufacturing cost of the electrode plate.The gist is that the bottom surface has a mandrel that passes through it and has multiple cylindrical protrusions whose outer diameter is approximately equal to the inner diameter of the tube. A box-shaped thermoplastic synthetic resin joint whose side wall height is larger than the height of the crown of the lattice body and whose upper part is open is attached to the crown of the lattice body, and from the top surface of the crown of the said joint It is characterized by applying heat to the upper portions of the left and right protruding side walls, bending them inward, and welding them together to cover the upper surface of the crown.

Fig. 2 shows a connecting seat 5 made of thermoplastic synthetic resin such as polystyrene and polypropylene cap, which is configured in a box shape so as to cover the bottom and side surfaces of the crown part 3 of the lattice body shown in Fig. 1. A cylindrical projection 6 is provided on the bottom surface of the tube for penetrating the mandrel 2 and fixing the tube. The cylindrical protrusion 6 has an outer diameter approximately equal to the inner diameter of the duplex, and is provided to match the pitch of the mandrel 2 shown in FIG. Also,
The height of the side wall 7 of the connecting seat 5 is designed such that when the connecting seat is attached to the crown part 3 of the lattice body 1, its upper part protrudes from the upper surface of the crown part by at least 1/2 of the width dimension of the crown part. ing.

製造工程の機械化が容易どなる等、多くの利点がある。Effects of the Invention The manufacturing method of the present invention is as described above, and since the connecting seats completely surround the outer periphery of the crown of the lattice body and are welded together, even if the storage battery is used at high temperatures, the connecting seats will remain intact even when the storage battery is used at high temperatures. It is possible to prevent bridge short circuits between the positive and negative electrode plates due to accumulation of fallen active material on the L part of the electrode plate in clad storage batteries, as well as to prevent the lattice from interfering or coming off. There are many advantages, such as the installation work of the connecting seats can be done in raw format, and the mechanization of the manufacturing process of clad type electrode plates can be easily done.
