どが増加する。Conventional technology and its problems In conventional sealed lead-acid batteries with clad anode plates,
They used tubes made of glass fiber fabric hardened with resin. However, these tubes have large openings and holes in the active material, so they cannot prevent short circuits by themselves.Therefore, clad type tubes require a separate separator between the electrode plate and the cathode plate, which increases the cost. , man-hours, etc. will increase.
又、電池の内部抵抗が増加するという欠点がある。Another disadvantage is that the internal resistance of the battery increases.

するものである。Purpose of the Invention In view of the above-mentioned conventional drawbacks, it is an object of the present invention to provide a sealed lead-acid battery that uses a tube with a sufficiently small pore diameter, eliminates the need for a separator, and has improved discharge performance at a low cost. .

The feature is that a sheet made by 1lllt and having many micropores with an average pore diameter of 2μ or less is made into a tubular shape, and a Kufud type anode plate manufactured as a tube is brought into direct contact with the #electrode plate using a gelled electrolyte. It is something to do.
実施例 以下、本発明をその一実施例により説明する。Example The present invention will be explained below with reference to one embodiment thereof.

着面となる一方の端部において予めその微孔塗布層を剥
がすことにより、熱溶着がうまく行われるようにした。Example 1: Acrylonitrile-butadiene-styrene copolymer (ABS resin) was used as the synthetic resin, and a mixture of this and a tetrahydrofuran solvent and isodevil alcohol-M non-solvent was applied to a polyester nonwoven fabric. The volatile components were removed to form a sheet. The average pore diameter of this sheet was 0.6 μm, and the maximum pore diameter was 2 μm. A tube having an inner diameter of 9 mm and a length of 275 mm was prepared by spirally winding the V-t with the microporous coating layer side facing inside and heat welding the overlapping portions. At this time, V

タとしての機能を有さなくなるからである。The reason why this microporous coating layer is placed on the inside is that if it is placed on the outside, tensile stress will be applied to the microporous coating layer, causing it to crack and no longer function as a separator.

ル化させた。Using this tube, a clad anode plate was manufactured using a conventional method. An electrode group was assembled by alternately stacking this and a cathode plate using an active material to which no organic antishrink agent was added. A sulfuric acid aqueous solution having a specific gravity of 1.220 to 1.280 was used as the electrolytic solution, and 3 to 7 wt % of silicon dioxide was added thereto to form a gel.

出すためである。In conventional batteries of this type, a separator is placed between the clad anode plate and the cathode plate to prevent short circuits, but in the present invention, the separator is not used and the cathode plate is directly connected to the clad type battery. This configuration is in contact with the tube of the anode plate. Note that using an active material to which an organic anti-shrink agent is not added to the cathode plate is because using an active material to which an organic anti-shrink agent is added will cause the cathode active material to swell and leak the electrolyte between the anode and cathode plates. This is to drive them out.

A tube with an inner diameter of 9 m and a length of 275 fIII was created by spirally winding this 5y-) and heat welding the overlapping parts.

る。In the present invention, the maximum pore diameter of V-) needs to be 2μ or less. In other words, if this maximum pore diameter exceeds 2μ, particles of the active material will leak and cause a short circuit.Advantageous Effects of the Invention According to the present invention, a tube with a sufficiently small pore diameter is used to separate the separator. Since it can be made unnecessary,
The distance between the anode plate and the cathode plate is reduced accordingly, and the internal resistance is therefore reduced, making it possible to obtain a sealed lead-acid battery with good performance such as positive discharge characteristics. Further, according to the present invention, since a separator can be omitted, it is possible to provide a sealed lead-acid battery with good productivity and low cost.
