【発明の詳細な説明】 産業上の利用分野 本発明は鉛蓄電池用極板の改良に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to improvements in electrode plates for lead-acid batteries.

However, increasing the amount of sulfuric acid lowers the hardness of the paste, making it difficult to fill the lattice.

向上させることができる。Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks and is characterized by the presence of germanium in the paste, thereby (a) improving the mechanical strength of the electrode plate and making it possible to (b) It is possible to increase the hardness of a paste containing a large amount of sulfuric acid and improve the filling properties of such a paste.
実施例 以下、本発明を実施例によって説明する。Example Hereinafter, the present invention will be explained by examples.
実施例１
理論電気５１１２Ａｈの自動車電池用正極板をペースト

た。Example 1 Positive electrode plates for automobile batteries with a theoretical capacity of 5112 Ah were produced by varying the amount of germanium oxide (Ge 02 ) added in the paste. The paste density was 4.0(]/Cm3.

The time was set to 3 minutes.

加量を０．５％までにしたのは、これを越えるとペース
トの硬化が早く、充填が困難であったからである。Electrode plate 1 was a conventional electrode plate using a positive electrode paste to which no germanium oxide was added, and 45% of the active material fell off due to vibration. On the other hand, germanium oxide is 0.1 to 0
．． The electrode plates 3 to 5 according to the present invention containing 5% additive had a shedding amount of 7.
% or less, and there was a tendency that the larger the amount added, the less the amount of falling off.Here, the reason why the amount of germanium oxide added was limited to 0.5% is that if it exceeds this amount, the paste will deteriorate. This is because it hardens quickly and is difficult to fill.
次に、これらの極板を用いて公称容量２８Ａ ｈの自動
車用電池を作製し、ＪＩＳＤ５３０１に準じて寿命試験
を行った結果を第２表に示す。Next, an automobile battery with a nominal capacity of 28 Ah was prepared using these electrode plates, and a life test was conducted according to JISD5301. The results are shown in Table 2.

ても同様の効果が見られた。Battery 1 was a conventional battery using positive electrode paste 1- to which no germanium oxide was added, and its life span was reached after 275 cycles. On the other hand, batteries 2 to 5 according to the present invention to which germanium oxide was added in an amount of 0.05 to 0.5% had a life performance of 305 times or more, and the life performance improved as the amount added increased. Similar effects were also observed when metal germanium powder was used instead of germanium oxide.
実施例２
通常の鉛粉および比重１．１０ （２０℃）の硫酸（
練り液）を用い、硫酸量を変えてペーストを作製した。Example 2 Ordinary lead powder and sulfuric acid with a specific gravity of 1.10 (20°C)
Pastes were prepared using a paste (kneading solution) and varying the amount of sulfuric acid.

かったものを示す。- Varying amounts of germanium oxide (Ge02) were added to this paste to fabricate an automobile battery with a nominal capacity of 28Ah (5hR). Table 3 shows the 5hR capacity of the produced battery. Note that the * mark indicates that the paste was too soft to be filled into the grid, and the * mark indicates that the paste was too hard to be filled.

％（公称容量比、電池８）の放電電気量が得られた。Batteries 6 to 10 were conventional products without the addition of germanium oxide, but if the sulfuric acid m was less than 100 cc per 1 kg of lead powder, the paste was too hard, and if it was more than 200 cc, the paste was too soft to be filled. Additionally, within this range, there is a tendency for the capacity to increase as the amount of sulfuric acid increases, with a maximum of 110
% (nominal capacity ratio, battery 8) was obtained.
一方、本発明により酸化ゲルマニウムを添加した電池１

, the sulfur weight that can be filled is 150 to 250cc/lead powder k

The amount of discharged electricity increased to ~300cc/lead powder, and the amount of discharged electricity was 118% at maximum (nominal capacity ratio).
同じ硫酸量で５ｈＲ容量を比較すると（Ｎｏ、 ７と
１２、Ｎｏ、８と１３と１８． Ｎｏ、 １４と１９）
酸化ゲルマニウムの添加量によるこれらの差は無く（そ

きた。Comparing the 5hR capacity with the same amount of sulfuric acid (No. 7 and 12, No. 8, 13 and 18. No. 14 and 19)
There is no difference in these depending on the amount of germanium oxide added (nominal capacity ratio is 104%, 110% and 114%, respectively).
The difference in capacity mentioned above is thought to be due to the amount of sulfuric acid used in the paste wire element. In this way, by adding germanium oxide to the paste and increasing the amount of sulfuric acid used in the wire element compared to the conventional method, it was possible to increase the initial capacity.

。In addition to the effects of the invention, as shown in the examples, adding germanium to the active material as in the present invention (a) improves the mechanical strength of the unformed electrode plate and the life performance of the battery; (b) It has great industrial value, as it enables filling of low-density paste with a large amount of sulfuric acid, increasing strength and discharge capacity.
