PRIOR TECHNOLOGY There are many possible causes of battery capacity deterioration in lead-acid batteries, but this is the most commonly thought of. The problem is that the active material becomes muddy and falls off. However, the battery capacity tends to decrease in the early stages of battery life, and this is thought to be caused by the adhesion between the active material and the grid. On the other hand, M of lead-acid battery
With the growing demand for F (no maintenance required), there is an urgent need to put Pb-0a alloy lattice into practical use to replace the PB-SB alloy lattice used in conventional electrode plates. In electrode plates using a Pb-0a alloy lattice, battery capacity deterioration is further accelerated. Therefore, in order to increase the adhesion between the active material and the lattice, the composition and additives of the Pb-0a alloy lattice have been studied.90 Problems to be Solved by the Invention The above Pb - The Oa-based alloy lattice has a problem in that the adhesion between the active material and the lattice is weak 〇 Means for solving the problem The present invention solves the above problem, and the lattice is filled with paste. After aging and drying the paste filling plate after the paste filling step of forming a C paste filling plate,
The anode plate and the cathode plate are formed by immersion in a chemical conversion tank containing dilute sulfuric acid at a predetermined concentration and a predetermined temperature. After the leaving step, the anode plate and the cathode plate are immersed in a dilute sulfuric acid bath and left for a predetermined period of time. Chill with something electric.

傍が、ち密な厚いα−ｐｂｏ、となり、表面側は、ち密
な厚いβ−ｐｂｏ、となっている。Function The lead-acid battery manufactured by the manufacturing method of the present invention has dense and thick α-pbo near the lattice, and dense and thick β-pbo on the surface side.

実施例
通常の化成では、陽極の活物質はβ−ＰｂＯ。α-pbo generally has poor reactivity, and β-PbOt has high reactivity. Therefore, even if deep discharge is performed, the reaction occurs on the lattice surface side and does not proceed inside the lattice, and the adhesion between the lattice and the active material is maintained, suppressing battery capacity deterioration. In this chemical formation, the active material of the anode is β-PbO.

にリッチになると初期の電池容量が小さくなり、サイク
ルをくり返すと電池容量が増加するうこれは、α−Ｐｂ
Ｏ，が充放電によりβ−ｐｂｏ、になるためで、これで
は前記効果がない。したがってこのα−ｐｂｏ。It is recognized that only α-pbo is produced, and that when it is made neutral, α-pbo increases. However, when α-PbOt becomes rich in the active material, the initial battery capacity becomes small, and when the cycle is repeated, the battery capacity increases.
This is because O, becomes β-pbo due to charging and discharging, and this does not have the above effect. Therefore this α-pbo.
