Abstract
Description
【発明の詳細な説明】
最近の自動車用鉛蓄電池は自動車の燃費向上により富に
軽量化の方向に押し進められている。DETAILED DESCRIPTION OF THE INVENTION In recent years, lead-acid batteries for automobiles have been increasingly made lighter due to improved fuel efficiency of automobiles.
その結果として陽極板、陰極板の活物質量も減らす方向
に推移し電池規格も起動性能面から見て低率容量を重視
するより高率容量を重視する方向に変わってきている。As a result, the amount of active material in the anode and cathode plates is decreasing, and battery standards are also changing from a starting performance perspective to placing more emphasis on high rate capacity than on low rate capacity.
陰極板の活物質をへらすと常温、特に低温での高率放電

等欠点が多く１−
格子体への充填が出来なくなる欠点があった。If the active material of the cathode plate is weakened, the high rate discharge performance at room temperature, especially at low temperature, will be reduced, and therefore it cannot be weakened very much.For this reason, it is considered to include a large amount of lignin in the additive. However, pastes made by adding a large amount of lignin using the conventional method have many drawbacks, such as the paste becomes soft with a small amount of water, and the water in the paste is liberated and hardens in a short period of time. There was a drawback that it became impossible to fill.

ト状態になり充填が出来な（なる欠点があった。In other words, the conventional method for preparing cathode paste is to prepare lead powder by dissolving additives such as barium sulfate 02 to λθ, lignin O1 to 04, and carbon θ to 05 in powder form or in necessary water. Ta. When a paste is made under these conditions, lignin adsorbs to the surface of the lead powder particles and covers the surface, so if a large amount is added, the paste becomes like the one shown above, making filling impossible.
本発明は上記欠点を除去するものである。The present invention eliminates the above drawbacks.

でも高率放電性能を高めることができるものである。An embodiment of the present invention will be described. Focusing on the hygroscopic and water absorbing properties of carbon such as acetylene black, first mix a small amount of water with lignin 04-30 and carbon O1-05 to make the lignin adsorb onto the carbon and turn it into a pudding-like product. . The pudding-like substance adsorbed on carbon is added to lead powder in the usual manner, mixed, and the necessary adjustment water and mixing solution are added to create a paste. In the paste made in this way, since multiple lignins were adsorbed to carbon, the surface of the lead particles was not covered more than necessary, and no abnormality was observed in the properties of the paste. In the cathode plate made using this paste, a large amount of lignin is adsorbed to the carbon contained inside the active material, so even if lignin is eluted into the electrolyte during charging and discharging, it is still adsorbed to the carbon. Due to the presence of lignin, it is possible to maintain its performance as a cathode plate over a long period of time, and even with a small amount of active material, high rate discharge performance can be improved.
