JPS61151966A - Manufacture of enclosed type lead storage battery - Google Patents

Abstract

PURPOSE:To eliminate necessity of charging after assembling an enclosed type lead storage battery, by assembling said battery in such a manner as using plates as they are dried without washing them in water, after dipping, in sulfuric acid, the upper parts of said plates that have been washed in water and dried after being formed. CONSTITUTION:The plate forming 1, washing and drying 2 and dipping 3 of the plate upper side in sulfuric acid are processed in order, and then, the plate drying 4 is processed in that condition without washing in water, and a lead storage battery is made through the battery assembling 5, and it is sealed by enclosing after water-activation 6. It is, therefore, not necessary to charge the battery again after being assembled, and it is possible to manufacture the enclosed type lead storage battery with long life using a higher shaped plate.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a method for manufacturing a sealed lead acid battery.

Conventional technology Conventionally, in sealed lead-acid batteries using glass mats, as the height of the electrode plates increases, the difference in electrolyte concentration between the top and bottom of the electrode plates increases during charging and discharging of the battery, resulting in a decrease in battery life performance. It is known to reduce In order to prevent these drawbacks, there are two methods: (1) a method of impregnating the glass mat with an electrolyte with a specific gravity of 1;
) I'm having a rough idea of how to set it up. (In the case of υ, there are two possible methods: impregnating the battery with electrolyte before assembling it, and impregnating it after assembling the battery, but in the former case, it is necessary to assemble the battery while keeping the amount of electrolyte impregnated constant. In the case of (2), the assembly method must be complicated, and in the latter case, the electrolyte has two layers, so the injection method must be complicated. Since it is necessary to discharge the battery, man-hours such as equipment and wiring necessary for discharging are required, and furthermore, the necessary power must be consumed for charging after battery assembly.

Problems to be Solved by the Invention In view of the above-mentioned problems, the present invention can assemble and inject batteries in the same simple way as before, and can be used without charging after assembling the battery. The present invention provides a method for manufacturing a sealed lead-acid battery using tall electrode plates, which has improved life performance.

Means for Solving the Problems The present invention is characterized in that the upper part of the electrode plate, which has been chemically formed, washed with water, and dried, is immersed in sulfuric acid, and then a battery is assembled using the dried electrode plate without washing with water. That is.

Operation The present invention has the above-mentioned features, and the process is as simple as dipping the electrode plate in sulfuric acid and then drying. It is possible to assemble the battery and inject liquid in a simple manner, and to manufacture a long-life sealed lead-acid battery using high-sized electrode plates that does not require charging after battery assembly.

Example An embodiment of the present invention will be described.

As shown in FIG. Assembly 5
Through the process, the lead-acid battery shown in Figure 2 is created, and after injection 6 (= sealed).

In this example, an electrode plate with a height of 30α is used, and the upper half of the chemically treated electrode plate, which has been washed and dried, is immersed in sulfuric acid with a specific gravity of 1.400, and after drying the electrode plate, the battery is assembled. It came out. The injection specific gravity after battery assembly was 1.240, compared to 1.300 for the conventional product. In addition, by assembling a battery using a plate whose upper part is immersed in sulfuric acid and injecting an electrolyte with a concentration lower than the average concentration of all electrolytes, electrolysis at the top and bottom of the plate during battery charging and discharging can be prevented. The liquid concentration can be equalized by -C;
Compared to conventional batteries, battery life can be increased by simply soaking and drying the chemically formed electrode plates.

The industrial advantages include the fact that batteries can be assembled and injected using the same simple methods as conventional methods, and there is no need to re-charge the battery after battery assembly. Great value.
