行った。Next, FIG. 2 shows a charge / discharge cycle test result of the ladder type lead storage battery according to the present invention shown in the drawings, in comparison with that of the conventional clad type lead storage battery. The lattice alloys were all lead-calcium-tin alloys with the same composition. The discharge is 5
Up to 1.7 V / cell at a time rate, charging at 10 V at a constant voltage of 2.4 V / cell
Time went on. The charge / discharge cycle test was performed on the battery A with the gap between the tip of the cored bar and the lower joint being 0, and the batteries B to E with the cored bar length of 1/200, 1/100, 1/20 and 1/10, respectively. went.

ら1/20とする必要がある。In the conventional product A in which the tip of the core is fixed to the lower seat and the battery B in which a gap of 1/200 of the core long metal is provided between the tip of the core and the lower seat, the lower seat 6 is formed by the extension of the core. The positive electrode active material 4 inside the tube falls off from the tube 3,
Although the life was shortened from 1000 to 1250 cycles due to a short circuit with the negative electrode plate, 1/100 to 1
In the clad battery according to the present invention having a / 20 gap,
Even if the mandrel extends, the articulation does not come off the tube
Life cycle performance of 1500 cycles or more was obtained. In addition, when the gap between the lower end of the core bar and the lower seat is increased to 1/10 of the core bar length, the capacity is considerably reduced, so the gap needs to be 1/100 to 1/20 of the core bar length. .
