せる原因となることか多々ある。It is a well-known fact that lignin and carbon are used. Among these additives, carbon forms stractures in tribasic lead sulfate, lead oxide, or the unformed active material, which is the main component, and increases the electrical conductivity of the active material a. By the way, after completion of chemical formation, the cathode plate of the closed ship storage pond is washed with water, dried, and cut to the specified dimensions, and then assembled together with other parts. It will take a few days until it is ready, so
The surface of the cathode active material reacts with oxygen or carbon dioxide in the air to form lead oxide or lead carbonate. Therefore, when the electrolyte is injected after completing one assembly, these parts may turn into lead sulfate, cover the surface of the active material, and inhibit the diffusion of the electrolyte into the active material, or the conductivity of the lead sulfate itself may be low. Therefore, the initial charging is often not carried out quickly, which often causes a deterioration of the appearance of the cathode plate.

本発明品か優れていることかわかる。The purpose of the present invention is to solve the above-mentioned problems and improve initial charging characteristics.
The object of the present invention is to obtain a skin electrode plate for a sealed lead-acid battery that has excellent initial performance and excellent heat resistance. In order to achieve the above object, the present invention has been developed by adding 10 times (2%) of acetylene black to the cathode as compared to the conventional additive amount. Inside active material 1
By adding this, acetylene black is dispersed at a high concentration in the active material, and lead sulfate particles (
By incorporating a large number of acetylene black particles into the core, the conductivity of the lead sulfate particles is increased, allowing the initial charge to proceed to the container, and improving the initial performance of the cathode plate. FIG. 1 shows the initial charge characteristics, and FIG. 2 compares the room temperature low rate discharge performance of the cathode plate after the first light, and it can be seen that the products of the present invention are superior in both cases.
