る。Lead paste obtained by kneading with dilute sulfuric acid etc. is mixed with lead (
(including lead alloys), expander cut metal,
It is obtained by a process of filling a support such as punched metal into grooves, aging and drying. As described above, the paste-type lead negative electrode plate has a simple manufacturing method and electrode structure, and therefore has good discharge characteristics while the number of charge/discharge cycles is small. However, as repeated charging and discharging progress, the active material held on the electrode plate, that is, the above-mentioned lead paste converted by chemical conversion, shrinks and becomes inactivated significantly, and the characteristics begin to deteriorate. Among the discharge characteristics, the severe low temperature required for starters of internal combustion engines, etc.
In order to improve the rapid discharge characteristics, increasing the amount of water or dilute sulfuric acid added to the lead paste to increase the porosity of the electrode plate will reduce the bonding strength between the active materials and shorten the lifespan. On the other hand, if the porosity was lowered in order to extend the service life, it was inevitable that the discharge characteristics would be lower than 1. Attempts have been made to add magical additives to the paste in order to improve its rapid discharge characteristics or lifespan. For example, the addition of carbon dioxide, silicon dioxide, alumina, carbon dioxide, etc. to the paste increases the porosity of the paste, strengthens the bonding of powder particles in the paste, and improves low-temperature rapid discharge performance. It is hoped that this will improve the quality of the product and extend its lifespan. However, even with the use of these additives, there is still room for improvement in low-temperature and rapid discharge performance and lifespan.

This can be done at any stage of lead-based preparation, such as by adding sodium 7-aluminosilicate powder to the lead base. A compound whose main component is zeolite, of which representative examples include sodium aluminosilicate (r:f, sodalite, A-type zeolite, X-type zeolite, Y-type zeolite, etc.) can be used, but any composition of Even when using an aluminosilicate sorter, the addition ratio to lead powder is approximately 0.3.
~5 weight ratio is preferred. When the addition ratio of sodium aluminosilicate to the lead powder compound is less than 0.3 mw, there is almost no effect of adding sodium aluminosilicate, and 5
It is clear that if the weight ratio is exceeded, the inverse VC characteristics deteriorate.

れる、。Effects of the Invention The present invention provides a paste-type negative electrode plate with excellent rapid discharge characteristics at the lower part and excellent life characteristics during repeated charging and discharging by applying a lead paste containing an aluminosilicate sorter to the support of the negative electrode plate. It is possible to make 11 paste-type lead electrode plates. The reason for this effect of the present invention is that, for example, sodium aluminosilicate is porous and has excellent adsorption properties for cations, which prevents the movement of imen sulfate and lead ions during charging and discharging of the negative electrode. Alternatively, it is possible that it acts effectively on diffusion. However, it is thought that the porosity of the aluminosilicate sorter suppresses the shrinkage of the negative electrode active material due to repeated charging and discharging, thereby extending its lifespan.
