つ−Ｃ電池を人形化するど、内部抵抗が大きくなるとい
う弱点がある。There is a demand for storage batteries to be made into dolls for use in power storage and submarines (19). However, the lattice body, which is the path for charging and discharging current, is made of an alloy (1;), and its specific resistance is Approximately 2
X 10-5Ω・Cnl, approximately 12 times more sensitive than copper. However, when a -C battery is made into a doll, it has the disadvantage of increasing internal resistance.

かった。In order to prevent this, there have been attempts to use lead-plated copper material for the negative electrode grid, but due to the operational constraints of plating, the thickness is thin, less than 0.1 mm, and the plating layer easily peels off after 9 cycles of charging and discharging. In the case of compound Y1, copper is exposed, which inevitably has the disadvantage of lowering hydrogen overvoltage and increasing self-discharge.

鉛Ｊ：たは鉛合金格子体を負極板に用いることにある。The purpose of the present invention is to eliminate the above-mentioned drawbacks of large lead-acid batteries. The method consists in using a lead alloy grid for the negative electrode plate.
以下、本発明を図面によって説明１Ｊる。The present invention will be explained below with reference to the drawings.

1 is a moon, 2 is a thick frame or crosspiece, and the thick frame or crosspiece 2 is a plate, rod or tape 41 made of copper or copper alloy. It is contained within. Reference numerals 4 and 4 are thin crosspieces that do not contain the copper material 3 as described above. Further, the thick frame or frame 12 and the thin frame F14.4 are made of lead or a lead alloy.

電気、抵抗の改善効果が小さくなる。In addition, the thick frame or crosspiece 2 containing the copper material sill 13 is not only a frame or crosspiece that hangs down from the ears of the embodiment shown in the figure, but also a so-called picture frame around the four circumferences of the lattice body, and a diagonal line extending diagonally from the ears of the lattice body. It is too difficult to use crosspieces arranged in a shape1, and in order to embed the copper strips in a frame or beam, remove the oxides on the surface of the copper strips and apply oil.11) All you have to do is soak it in a molten metal of lead or lead alloy, take it out and cool it.Also, to roughly strengthen the adhesion between copper material and lead or lead alloy, A layer of gunmetal made of solder, lead, tin, and copper may not be interposed between the copper material, lead, or lead alloy.A thick frame or a frame 2 containing the copper material 3 obtained in this way, A grid body is formed by welding a part consisting of thin crosspieces 4, 4 separately produced by casting etc. Also, the thickness of the lead or lead alloy covering the copper material 3 is preferably 0.2 to 3 ml. If the layer is thin, it will become porous during charging and discharging, and the copper material will come into contact with the electrolyte, resulting in faster coating deterioration.On the other hand, if the layer is thick, the copper material will become relatively thin, and the electrical and resistance of the grid will decrease. The improvement effect becomes smaller.

If the alloy has more anti-7 than other grid parts, hydrogen gas will be generated from the thick frame or crosspiece 2 during battery release due to the difference in hydrogen overvoltage, and the other grid parts will turn into lead sulfate. A local battery is formed.

い。Therefore, in such an embodiment of the present invention, the thick frame containing the copper material or (1 lead or ε) alloy becomes porous early due to charging and discharging, and the steel material 1 becomes porous due to the electrolytic solution. There is no risk of contact and increasing self-discharge.Also, only the thick crosspieces in the grid body are made to contain copper material, so even if the crosspieces containing copper material Even if the lead or lead alloy becomes porous due to charging and discharging, and the copper 4Δ1ift comes into contact with the electrolyte, the increase in self-discharge caused by this can be minimized. There is no need to reduce the volumetric efficiency of the battery as in the case where the battery is used.
