す。 The illustrated embodiment shows a lattice substrate A of the present invention manufactured by punching from a thin rolled lead blank, and the substrate A has the following features:
A rectangular outer frame 1 whose wall thickness is increased by bending has a large number of parallel vertical lattice bars 2 . . . and a large number of parallel horizontal lattice bars 3 perpendicular thereto. It has an ear 4 projecting upward in the middle of the frame part 1a, and has a leg 5 projecting downward in the lower edge frame part 1b,
Inside the outer frame 1, a large number of rectangular active material filling holes 6 are defined by these vertical and horizontal lattice bars 2, 3...
is formed. The above configuration is no different from conventional grating substrates of this type. According to the present invention, the vertical lattice bars 2... are arranged with the following density. That is, at least two ears directly below and in the vicinity of the middle ear 4 are arranged relatively densely with a relatively small distance 5a from each other, and those located further away from each other are arranged relatively closely apart from each other with a relatively large distance 5b. In the illustrated example, a total of four vertical lattice bars 2, 2, 2, 2, two directly below the middle ear 4 and two on both sides thereof, are arranged relatively roughly. They are arranged so that there is a small interval 5a of 12 mm. In this case, the rightmost crosspiece 2 and outer frame 1
The distance from the right edge frame portion 1c is also 8 mm. On the other hand, the two vertical lattice bars 2 on the left side far from the middle ear 4,
2 and the left side edge frame part 1d of the vertical lattice bar 2 on the right side of one side and the outer frame 1 on the left side of the other side.
and a large interval 5b of 15 mm between them. Thus, as a whole, the plurality of vertical lattice bars 2, 2 are concentrated near the intermediate ear 4, which improves the current collection efficiency of the ear 4 and also reduces the mechanical strength of the board against external shocks and loads received on the ear 4. A product with high target strength can be obtained. In this case, especially the ear 4 as shown.
1.5 to 2 mm wider than the narrow width 2b of the other vertical lattice bars, which is 1 mm or less.
If the width 2a is made as wide as possible, the above effect will be further improved. In this case, it is advantageous if the width of the other vertical lattice bars 2 is 1 mm or less, since a lightweight lattice substrate can be obtained. The area having the large spacing 5b of about 15 mm on each side suffices with a relatively small number of vertical lattice bars 2, 2, which reduces the weight of the substrate and provides good retention of the filled active material.

本考案によれば、その比較的小間隔５ａの範囲
は８mm〜10mmであり、比較的大間隔５ｂの範囲16
mm〜18mmであることが集電効率、機械的強度、軽
量性と充填活物質等の保持等の点から好ましい。 According to the present invention, the relatively small interval 5a ranges from 8 mm to 10 mm, and the relatively large interval 5b ranges 16
The thickness is preferably from mm to 18 mm from the viewpoints of current collection efficiency, mechanical strength, lightness, retention of the filled active material, etc.

つ軽量なものに得られる等の効果を有する。 In this way, according to the present invention, the vertical and horizontal lattice bars 2 of the vertical and horizontal lattice board for lead-acid batteries are arranged relatively densely, with several bars directly below the intermediate ears 4 and in the vicinity thereof, particularly with relatively small intervals 5a. On the other hand, since the remaining few wires farther from the intermediate ear 4 are arranged relatively sparsely with relatively large intervals 5b, the current collection efficiency of the electrode plate is improved compared to the conventional vertical lattice board of this type. It has the effect of improving mechanical strength and making it lightweight.
