Prepare a 2V0.5Ah sealed lead-acid battery made with the configuration shown in Fig. 1, and treat the pole column with a length of 5mm with various alloy compositions, pretreatment, coating agent, and seal it by heat welding. The following table shows the results of comparing the penetration resistance of the electrolytic solution by allowing the cells to stand for 30 days at 60 ° C for 30 days for each leakage resistance performance.

It was dipped in the agent or coated with a coating agent. As shown in Examples 1 to 14, the type of pole column alloy is Pd-Ca-Sn system, Pb-As-Sn system and Sn content 0 to 0 in consideration of castability, alloy strength, and battery characteristics.
Compared with 5%, in order to obtain a pole column alloy having a higher Sn content, the pole column portion after polishing was dipped in a solder bath to form a solder coating to control the Sn content on the pole column surface.

Examples 1 to 19 and 21 are shown and dissolved in toluene
A comparison was made between the CSM coating and the method of sandwiching a sheet-shaped CSM with a thickness of 0.1 mm during heat welding.

The higher the content, the higher the effect of preventing penetration of the electrolyte into the positive electrode column, and the effect was seen at 0.3% or more. The same effect was obtained with 63% Sn alloy, which is eutectic solder in solder dip. Therefore, the optimal Sn content in the pole column is about 0.3 to 3% considering the battery performance, and if the Sn amount is controlled only on the pole column surface by performing solder dipping, etc., Sn is eutectic solder.
63% is possible.

1/2〜1/4に減少し、シート状CSMで極柱を挟み込んで熱
溶着する方法でも、同等の効果が得られた。Many of the pretreatment agents were harmful to the negative pole, and no effect was seen, but the positive pole was treated with sulfuric acid or phosphoric acid to stabilize lead sulfate and lead phosphate. The method of forming the coating is effective, and the electrolyte permeation rate is higher than that of CSM alone and the conventional epoxy coating.
It was reduced to 1/2 to 1/4, and the same effect was obtained by the method of sandwiching the poles with sheet-like CSM and heat welding.
CSMは、下記のような模式的構造を有し、耐薬品性，
耐候性等に優れ、塩素含有量25〜50wt％，イオウ含有量

Excellent weather resistance, chlorine content 25 ~ 50wt%, sulfur content
0.5 to 1.5 wt%, the Cl group imparts rubber elasticity,
It is considered that the SO 2 Cl group is combined with PbO and Sn oxides on the surface of the lead alloy by hydrolysis, and strong adhesion can be obtained.

Of course, it is also possible to maintain the liquid-tightness and airtightness of the poles by injection molding of PE resin.

ことが可能になり、特に小形の密閉形鉛蓄電池を高容量
化することに対して有効である。 In this way, the pole pillar containing 0.3% to 63 wt% Sn on the pole pillar surface is pre-treated with sulfuric acid and phosphoric acid for the positive pole, and the negative pole is directly coated with CSM or sandwiched with sheet-like CSM for heat welding. By doing so, the electrolytic solution permeation rate is reduced to 1/2 to 1/4 compared to the conventional epoxy coating method, so the welding length of the pole post sealing part is shortened from the conventional 5 mm to 2 to 3 mm. This is especially effective for increasing the capacity of small sealed lead acid batteries.

なるという効果が得られる。As described above, according to the present invention, the CSM has a high surface Sn concentration and is coated with a sulfuric acid or phosphoric acid-treated pole column or sandwiched between the pole columns by heat welding to seal the pole columns. As a result, compared with the conventional epoxy coating method, the electrolytic solution permeation rate is significantly reduced, and the pole column can be sealed in a highly reliable, liquid-tight and airtight manner, and the sealing length of the pole column can be shortened. become,
It is possible to obtain the effect that the sealed lead-acid battery has low cost and high volume efficiency.
