Abstract
Description
【発明の詳細な説明】 本発明は、鉛蓄電池用陰極板に関する。[Detailed description of the invention] The present invention relates to a cathode plate for lead-acid batteries.
従来の鉛蓄電池に於いては、その容量を支配するのか陽
極であったため、陰極の利用率向上という事はあまり行
なわれなかった。In conventional lead-acid batteries, since the anode dominates the capacity, little effort has been made to improve the utilization of the cathode.
しかし、近年、省資源、省エネルギーという観点からの
鉛蓄電池の軽量化という要求により陰極板重量の低減と
いう事も不可欠となった。However, in recent years, it has become essential to reduce the weight of the cathode plate due to the demand for lighter weight lead-acid batteries from the viewpoint of resource and energy conservation.
この解決手段として、陰極活物質の多孔度。The solution to this problem is the porosity of the cathode active material.
比表面積を増加させる事Ｉこより、利用率を向上させる
ために、熟成工程、乾燥工程を経て活物質となるペース
トの含水１を大きくする事か行なわれた。In order to increase the specific surface area and improve the utilization rate, attempts were made to increase the water content 1 of the paste that becomes the active material through a ripening process and a drying process.
しかし、従来のペースト仕様では、水を多量１こ追加投
入すると、ペーストか軟かくなり過ぎ。However, with conventional paste specifications, if you add a large amount of water, the paste becomes too soft.
通常の鉛合金の格子体ｌこペーストを充填する装置ては
充填直後１こ格子体からペーストか垂れ下がる等の問題
かあり、作業性という点から、ペースト含水量を大ｒｆ
Ｊに増大できないという欠点かあった。With conventional equipment for filling lead alloy grid paste, there are problems such as paste hanging from the grid immediately after filling.
J had the drawback of not being able to increase.
本発明の目的は、含水量か大きく、シかも作業性のよい
陰極用ペーストを用いる事により。The object of the present invention is to use a cathode paste that has a high water content and is easy to work with.
活物質利用率の高い上−こ寿命性能のよい陰極板を提供
する挙上〔ある。There is a method that provides a cathode plate with a high active material utilization rate and a good life performance.
上記の目的を達成するために、本発明は陰極ペースト中
のリグニンを鉛粉重量に対してαｌ〜０３％にするもの
である。以下に説明するリグニンの添加量は陰極板の鉛
粉重量に対するものである。In order to achieve the above object, the present invention makes the lignin content in the cathode paste to be αl~03% based on the weight of the lead powder. The amount of lignin added described below is based on the weight of lead powder of the cathode plate.
電池に於ける陰極活物質中の添加剤の効果として、リグ
ニンは硫酸鉛結晶の粗大化を防止すると考えられている
。As an additive in the cathode active material in batteries, lignin is thought to prevent lead sulfate crystals from becoming coarse.

方か１８％多く含水させる事か可能である。なお第１図
において、Ｃはペースト性状か格子体番こ対して円滑に
充填か行なわれる領域である。Since lignin is a dispersant, the paste properties vary greatly depending on the amount added. Figure 1 shows the relationship between the water content of the paste, the penetration rate, and the amount of lignin added. 1st
In the figure, from the viewpoint of moisture content, if the upper limit of paste penetration for smooth filling is A, the corresponding moisture content is 11.7% for 0.2% lignin and 11.7% for 4% lignin α. α9%. In other words, it is possible to make lignin 02-chi contain 18% more water. In FIG. 1, C is a region where filling is performed smoothly due to the paste properties or the grid size.
第２図に、リグニン添加量と円滑に充填されるペースト
含水量の上限との関係を示す。FIG. 2 shows the relationship between the amount of lignin added and the upper limit of the water content of the paste that can be filled smoothly.
第２図から、α３チ付近より含水量か急激に減少する事
か判かる。From Figure 2, it can be seen that the water content decreases rapidly from around α3.

また。Regarding the effect of lignin on the battery I mentioned above, looking at the relationship between the amount of lignin added and the life according to the SAE standard, the relationship shown in Figure 3 is shown in the case of an N50Z type battery. However, the water content is the same for all. In other words, if the amount of lignin added is around 0.1%, the lifespan is sufficiently long.
Also.
これ以上添加してもあ筐り大きく変わらないことか判る
。It can be seen that even if more than this is added, the housing will not change significantly.
以上、第２図と第３図、それに含水量の増加か利用率増
加につながることから、寿命性能を大きく損なう事なく
、利用率を向上させるにはリグニンの添加量か０１〜０
３％の範囲か適当である事を見い出した。As shown above in Figures 2 and 3, and since either an increase in water content or an increase in utilization rate leads to an increase in the utilization rate, in order to improve the utilization rate without significantly impairing the life performance, the amount of lignin added must be 01 to 0.
It was found that the range of 3% is appropriate.
次に本発明の一実施例を説明する。Next, one embodiment of the present invention will be described.
同量の硫酸バリウムとアセチレン傘ブランクを添加した

Using a cathode paste that was kneaded with water and dilute sulfuric acid so that the water content reached the upper limit for smooth filling (penetration A shown in Figure 1), five types of batteries were manufactured using a conventional method. , an initial performance test and a 4000 cycle life test according to SAE standards.

放電番こよるものを示す。The utilization rate of the cathode active material in the first initial performance test at this time,
The relationship with the utilization rate of the cathode active material after the life test is shown in Figure 4. From FIG. 4, it can be seen that when lignin is 0%, the deterioration is severe due to life test 1, and when lignin is 04%, the initial utilization rate of the cathode active material is low. Note that this utilization rate is based on the 5-hour rate discharge number.

Lead powder I may also be added and kneaded, and it has been found that this method allows for more uniform dispersion of lignin in the paste than the former method, resulting in less variation in battery performance.
