It is desirable to reduce each of these ingredients to a light amount.

いる。However, there is a limit to how the active material and electrolyte can be made light: 1 because it is necessary to ensure a certain degree of bending performance. On the other hand, the lattice body occupies a large part of the song due to the lead content, and there is still room to reduce the weight as long as it is sufficient for concentration and retention of active qualities. . Therefore, the weight reduction of i WA j (C4μ is progressed exclusively by reducing the weight of the lattice body.

こめ電池の初期性能も劣・るという欠点があつｆこ。In order to reduce the weight of the lattice body, the general IJ'1 is to make it thinner, make the lattice bones thinner, and make the spacing between the T-pieces coarser. In this case, making the lattice thinner will reduce its @structural properties.
There are problems with paste filling properties, mechanical strength of the electrode plate, etc.
Naturally, there is a limit. On the other hand, if the spacing between the lattice bones is coarse, it is relatively easy to manufacture the electrode plate, but there is a problem with chemical formation. The central part of the t-eye is chemically formed t'

The drawback is that the initial performance of the batteries is also poor.

。The present invention eliminates the above drawbacks by treating the electrode plate after filling with paste with a dispersion of colloidal graphite.
The feature is that a graphite layer is provided on the surface of the electrode plate.

ｆこ極板が得られることがオつかつ１こ。Graphite has relatively good electrical conductivity, and is a good conductor similar to lead dioxide (JSEN 02) and metallic lead (Pb), and it also has excellent acid resistance and oxidation resistance. Colloidal graphite 0 dispersion is Iμ
A strong layer of graphite can be obtained by suspending a certain amount of fine particles in water or a medium and applying it to the target material. However, if this colloidal graphite dispersion is used, it is easy to provide graphite J- on the surface of the electrode plate, and it has excellent chemical formation properties.
One thing is that it is possible to obtain a f-sized electrode plate.

がわかる。It is approximately 2 mm thick, surrounded by horizontal lattice bones and vertical lattice bones, and has f squares, which are about twice as coarse as the conventional automobile 1 "Ikeda lattice. After filling one positive electrode storage battery paste prepared by a conventional method, approximately 20% of each paste was immersed in an aqueous dispersion of solid colloidal graphite to form a paste on both sides of the electrode plate to a thickness of approximately 100 μm. A graphite layer of about 100% is formed.The figure shows a cross section of an unconverted electrode plate on which the graphite layer is formed. .Well, = When the unformed electrode plate prepared in this way is immersed in dilute sulfuric acid, the dilute sulfuric acid penetrates well into the active material and forms on the surface of the electrode plate, resulting in a porous graphite layer. I understand that there is something.

や噴甥の方法で行９ても得られる効果は同すである。As described in detail above, according to the invention, the lattice bones are made lighter and coarser, and the conventional disadvantages of poor chemical formation properties and discharge performance are overcome by using a single lattice. This problem can be solved by providing graphite layers on both sides, which has great industrial value. In addition, in the embodiment of the present invention, a graphite layer is provided on the positive electrode plate 1.
Regarding this case, it is theoretically possible to obtain the same effect with the negative electrode plate.1. Graphite 1ω is formed using an aqueous dispersion of colloidal graphite and is performed by immersion. Instead, a quick-drying dispersion in any conventional medium can be used, and the same effect can be obtained even if the method is applied by coating or spraying instead of dipping.
