If the pressing force of the separator against the positive electrode plate active material is weak, the battery life will be shortened. Furthermore, if there is a difference in the pressing force of each cell in the battery case, the life of the assembled battery will be dominated by the life of the cell with the lowest pressing force. However, in conventional collective lead-acid batteries in which a predetermined gap is provided between the electrode plates and a separator is inserted into this gap, it is necessary to prevent the separator from being damaged when the separator is inserted into the gap. For this reason, in conventional collective lead-acid batteries, it is difficult to press the separator against the anode active material with sufficient pressing force, and differences in the insertion state of the separator cause differences in the pressing force inside the battery case of each cell. However, there was a limit to improving the life performance.

る。There is an extremely strong correlation between the force that presses the separator against the positive electrode plate active material, or in other words, the force that compresses the separator, and the battery life. Normally, battery life performance improves as the pressing force increases until the force for pressing the separator against the anode active material reaches 50 KQ/dm2. This means that if the pressing force is non-uniform within each battery case section, the life performance of the assembled battery will be dominated by the one with the lowest pressing force.

できるようになる。Therefore, in an assembled battery, it is important to keep the pressing force within each container part as uniform as possible. However, if the pressing force is increased, the porosity of the separator decreases and the amount of electrolyte retained decreases. Therefore, the pressing force of the separator 2 is determined while considering the required battery life, and the thickness of the separator is determined based on the required battery capacity. Further, the thickness of the separator is usually the thickness when pressed at 10 kg/dm2. Split separator 2 is 20kQ
The thickness when pressed at /d112 is measured, and the depth dimension of the electrode plate storage recesses 4 and 5 is determined. That is, recesses 4 and 5
It is preferable to set the sum of the depth dimensions to be as much as possible the sum of the thickness of the electrode plate and the thickness of the compressed separator. This allows the electrode plates in each cell to uniformly receive a pressing force of 20k (j/d++2) from the separator.

This is a 12V battery manufactured by inserting a separator. The materials used for the anode plate, cathode plate, and separator were substantially the same as in this example.
