It exhibits excellent effects when applied to large-capacity sealed lead-acid batteries.

た小容量密閉形鉛蓄電池に実用化されてきた。 A mat-like sheet (hereinafter referred to as a fine glass fiber sheet) made mainly of glass fibers with an average diameter of 1μ or less has been used as a separator that has better retention of electrolyte and better prevention of active material penetration. ) was proposed as a separator for sealed lead-acid batteries, and has been put into practical use, especially for small-capacity sealed lead-acid batteries that use plates with a height of approximately 120 mm or less.

傾向が大きいことに起因することが分つた。 However, for larger-capacity sealed lead-acid batteries, it may not be possible to obtain the desired performance simply by scaling up the dimensions of the electrode plates and separators made of fine glass fiber sheets of conventional small-capacity sealed lead-acid batteries. found. In other words, according to experiments conducted by the inventors, when a lead-acid battery is made using, for example, an electrode plate with a height of 180 mm and a separator made of a fine glass fiber sheet, and a floating charging test is performed, the capacity of the storage battery reaches its initial level after about 3 months. It decreased to 2/3 to 1/2. When investigating the above-mentioned drawbacks of this storage battery, it was found that due to the large height of the electrode plate, the amount of sulfuric acid present in the fine glass fiber sheet that is in contact with the upper part of the electrode plate is greater than the amount of sulfuric acid present in the sheet that is in contact with the lower part of the electrode plate. It was found that this was caused by the fact that the amount of electrolyte was smaller than the amount of sulfuric acid, that is, the electrolytic solution had a greater tendency to fall through the sheet and accumulate at the bottom.

ある。 The present invention has been made from the above viewpoint, and by using a separator in which an electrolyte impermeable part is arranged in a part of a fine glass fiber sheet so that the electrolyte does not penetrate easily, the electrolyte can flow downward. The object of the present invention is to provide a large-capacity sealed lead storage battery which prevents movement and makes the distribution of the amount of sulfuric acid in the separator uniform during use of the battery, and which has excellent battery performance.

That is, FIG. 4 shows anode active material isolation ribs 9' that isolate the anode active material in the vertical directions 7' and 8' on the anode plate 2', and cathode active material isolation ribs 9' that isolate the anode active material in the vertical directions 10' and 11' on the cathode plate 3'.
A cathode active material isolation rib 12' is provided to isolate the cathode active material, and each active material isolation bone 9, 12' is brought into contact with the electrolyte impermeable portion 6' of the separator 1'. By doing so, it is possible to prevent the movement of the sulfuric acid component in the vertical direction within the electrode plates 2', 3' and the separator 1', thereby making it possible to further ensure the uniformity of the sulfuric acid concentration distribution.

い。 Although two embodiments of the present invention have been described above with reference to the drawings, various other embodiments of the present invention can be considered without departing from the spirit thereof. For example, it is possible to treat the edges of a fine glass fiber sheet with a rubber-based adhesive that has high viscosity and is highly flexible after curing, and then adheres the treated parts together to form an electrolyte-impermeable part. It's a method. Further, the electrolyte-impermeable portion may be provided at a plurality of locations depending on the size of the storage battery, and may be provided not only in the horizontal direction but also in the vertical direction in the case of a wide separator. The same applies to the active material isolated bone, and this is also effective for improving the manufacturing strength of the electrode plate. In this case, it goes without saying that all of the active material isolation bones and the electrolyte impermeable part do not need to be in contact with each other.
