Abstract

PURPOSE:To obtain light weight and reduce a strap welding process by bending and combining each of the positive and negative electrode plates filled with the positive and negative electrode active materials while a strap substitution section is being left behind in an expanded grid in the horizontal and vertical directions. CONSTITUTION:In a positive electrode plate, 1 is a positive electrode expanded grid, 2 is a strap substitution section, 3 is a plate lug, and 4 is a positive electrode active material. In a negative electrode plate, 5 is a negative electrode expanded grid, 6 is a strap substitution section, 7 is a plate lug, and 8 is a negative electrode active material. The negative electrode plate is packed with an envelope separator 9 whose upper part only is opened and is bent alternately. Since both positive and negative electrode plates use the expanded grid, the expanded grid meshes section that corresponds to the strap can easily be bent. For combination, easy assembly is made possible by alternately bending the positive and negative electrode plates. Besides, shortcircuit can fully be prevented by the envelope separator covered with the negative electrode plate and there is no hindrance in the gas generation at the negative electrode plate due to the presence of the upper open separator.

Description

[Detailed Description of the Invention] The present invention relates to an improvement of a lead layer battery using an expanded lattice, and its purpose is to eliminate the need for welding straps, thereby reducing costs and improving the lightness of a single cell. It is.

In recent years, the importance of reliable resources and energy conservation has been advocated in all fields, and without exception lead-acid batteries are actively being improved in this regard. In particular, in response to the demand for smaller, lighter and warmer parts for local batteries, continuous technological innovations are being carried out, such as thinner single plates and ultra-thin separators. . Currently, we are in a difficult situation to fight for the release of second-hand goods without degrading battery performance.The first part, case F, and strap part are places where OJ can reduce the overlap. 7 is attracting attention.

As Ahi++1 A batteries become maintenance-free, the lattice alloy is changing from Pb-8b alloy to Pb-Ca alloy. By using Pb-Ca alloy, there is no loss of liquid during charging, and there is no self-charging.
Although it has advantages such as being resistant to shrinkage during storage, it is known that its @# property is inferior to Pb- and a-alloy lattice in strap welding.

The present invention uses extended band grids for both the +EtJli number and the negative plate, eliminates the need for a strap part, and reduces the battery's heat, thereby solving the problem regarding the molten layer in the 7 traps. This will provide a lead HIT pond.

Hereinafter, one embodiment of this Komyo will be explained in detail with reference to Kawamukai. Fig. 1 shows the main plate used in the present invention, l is the Seigang Expad grade F, 2 is the strap replacement part, and 8 is the replacement part for the strap. tsubaki ears,

Only the upper part of the single frame is opened, and it is wrapped with Lr envelope separator 9 and folded alternately. This is a perspective view of 6 positive Ii! Since both the Ii gradient and the negative brazing plate use Exband Raku F, it is possible to easily bend the Exband lattice mesh portion corresponding to the strap. Figure 5 is Figure 31, $4
I agree with the diagram, the positive board, the negative fI! It is a perspective view of a combination of J temporary. , +E, work, J and negative positives can be alternately folded to make it easier to understand. In addition, short circuits can be completely prevented by packaging the negative electrode with a novel lobe separator, and there is no problem with gas generation on the @1 plate than with the top-open separator.

From the first table! Considering the pond performance number, we were able to prove that the pond was reduced by 600 f! by walking around the pond.

From the following, the battery manufactured according to the present invention can save 5 to 6 hours by eliminating the need for a strap.
