Abstract

PURPOSE:To simplify manufacturing process by filling active material in a half- cut monoblock container in which part of current collector is embeded and melt- bonding a pair of containers with a separator interposed between them. CONSTITUTION:A current collector 2, a connector 3 which connects adjacent cells, and a conducting part 3' connecting to terminals are embeded in a side thick part 1' of a half-cut monoblack container 1 when the container is molded. Positive paste 6 and negative paste 7 are filled in each of a pair of containers. A pair of containers 1 are faced with a separator interposed, edges of containers are melt-bonded to fabricate a monoblock lead-acid battery. Therefore, stacking of plates, forming of strap and pole, and insertion of element into a container are eliminated. Manufacturing process is remarkably simplified and cost is reduced.

Description

[Detailed Description of the Invention] The present invention [US! I'Ll is the one.

14) Normally, a storage battery is made by filling the positive and f1 pole grids with paste, forming these plates in 11.1, and drying them. A strap and a ball are formed to form an element, which is inserted into a battery case, and in the case of a monoblock battery, the cells are connected in some way, and then the lid and the battery case are welded, and the ball and terminal are connected. The process involves 11 complex steps, including welding. Therefore, even if the battery capacity is small, these man-hours will not change;
The disadvantage is that the cost per unit is high.

The present invention provides a monoblock lead-acid battery that can simplify the above-mentioned complicated manufacturing process and is inexpensive to manufacture.

The monoblock lead-acid battery of the present invention uses a monoblock battery case in the form of a pair of half-cuts, which is obtained by vertically dividing a conventional battery case and a lid into two parts. A type 3 block battery case and a current collector are integrated, and a part of the current collector is embedded in the wall of the battery case and connected to the current collector of an adjacent cell with lυ. The paste was directly filled into the battery, and the half-cut monoblock battery containers each weighing 1 g were welded together via a lever lever to form a completed battery.

Unlike conventional fit storage batteries, the present invention has the above-described structure, and unlike conventional fit storage batteries, processes such as stacking electrode plates, forming straps and balls, and inserting elements into a battery case can be omitted, resulting in a significant reduction in manufacturing costs. It's a monkey.

Next, the present invention will be explained in detail with reference to the drawings. Figure 1 (
△) and (B) are plan views of essential parts of an embodiment of the present invention, not showing the state before assembly, and show a pair of half-cut monoblock battery containers; in the figure, '1' indicates a half-cut 2 is a current collector, 3 is a connector that connects the current collector 2 of the F3 contact hill, and 1 is embedded in the 19-thick part of the side wall of the battery case 1. Reference numeral 3' denotes a conductive part which is connected to the end R and is embedded in the thick side wall of the battery case 1 under the thick wall.

And ([3) shows the state in which the half-cut paste [•] was exposed to direct light, 6 is the positive electrode paste, and 714 is the negative electrode paste. Figure 3 C, 2nd
A pair of half-shaped seven-block battery containers filled with the pastes shown in Figures (Δ), 13, and (,B) are passed through a separator to -C? '1' or 'C' completed battery.

As described above, in Example J3 of the present invention, each of the pair of half-shaped seven-block battery containers with integrated current collectors is filled with positive and negative electrode pastes j~, and then the half-shaped seven-block battery containers are filled with positive and negative electrode pastes j~. A completed battery can be made by simply welding the block battery cases together via a hibernate (111). The manufacturing process can be significantly reduced compared to conventional methods.

In the embodiment, an example was described in which a half-shaped monoblock electric cell 41 is filled with paste, but fil powder or 3L granulated lead powder may also be filled.

As mentioned above, the monoblock lead-acid battery of the present invention can significantly reduce the number of manufacturing processes that were required to manufacture conventional monoblock lead-acid batteries of this type, and therefore can significantly reduce manufacturing costs. The benefits are worth it.
