本発明は蓄電池用セ・臂レータに係り、特に電解液の保
持性が改良された蓄電池用セ・ぐレータに関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a storage battery separator, and more particularly to a storage battery separator with improved electrolyte retention.

めである。! A mat-like sheet of glass fiber with an average diameter of 1 μm or less has been proposed as a separator for sealed lead-acid batteries, with a height of about 120 μm.
It has been put to practical use in small-capacity sealed lead-acid batteries using electrode plates similar to those described by Tomo. However, if the plate height is, for example, 180 m
In large-sized batteries with a battery size of more than m, there is a drawback that desired performance cannot be obtained because the amount of electrolyte retained in the upper part of the mat-like sheet is smaller than that in the lower part. This is because the diameter of the fibers is relatively large, so the height of liquid absorption due to capillary action is reduced.
このような欠点を解決しようとするものとして、マット

−１７６６６７号公報）。As an attempt to solve these drawbacks, a separator has been proposed in which an electrolyte movement prevention part is arranged in a part of a mat-like sheet to prevent the electrolyte from falling (Japanese Patent Application Laid-Open No. 57-1991).

する。However, it is not easy to form an electrolyte movement prevention part in the middle of the separator (in the same publication, the PVC resin is molded into an H-shaped cross section, and the upper and lower parts of the separator are inserted into the four parts, respectively). This makes the manufacturing process complicated and leads to a significant increase in costs.

小さいとこの移動速度が低下するように外るのである（
いわゆる“ガス抜け′が悪い）。In general, the smaller the fiber diameter, the better the liquid holding power, which is preferable, but it also increases the cost, and in the case of high-output batteries,
In other words, in storage batteries, the performance during rapid discharge deteriorates.
Generally, oxygen generated at the positive electrode moves through the liquid and reaches the negative electrode, where it becomes water. The higher the output power of the battery, the faster this movement speed must be, but if the fiber diameter is as small as 0.3 to 0.6μ, this movement speed will decrease (
So-called "bad gas release").

を要旨とするものである。In order to achieve this object, the separator of the present invention is designed to reduce the diameter of the fibers constituting the upper part of the separator, thereby increasing the electrolyte holding power due to capillary action in the upper part of the separator, In a storage battery storage battery in which fibrous substances are intertwined and formed into a sheet, the average diameter of the fibrous substances in the upper part of the separator is smaller than the average diameter of the fibrous substances in the lower part of the separator. The gist of this article is to create a ceno-9 for storage ponds.

ガラス繊維を５０重！１チまで含有することができる。Glass fibers are mainly used as the fibers constituting the separator/flat plate of the present invention. It is preferable to use glass fibers that have an average diameter of 1 μm or less for the entire separator. Specifically, the average fiber diameter of the upper part of the separator is 0.3 to 0.6 μm, and the average fiber diameter of the lower part of the separator is 0.3 μm.
Preferably, the thickness is 7 to 1.0μ. At this time, it is preferable that the difference in average fiber diameter between the upper and lower portions is 0.2 μ or more. In addition, when it contains 50 weights or more of glass fibers with a diameter of 1μ or less, 50 weights of glass fibers with a diameter of 1μ or more, for example, 10 to 30μ! It can contain up to 1 inch.

That is, paper is made by dispersing two types of glass fibers, large diameter and small diameter, in water, and at this time, the large diameter fibers are placed on the lower side of the separator, and the small diameter fibers are placed on the upper side of the separator. A slurry is prepared by dividing the feeding area into dispersion water so that a large amount of the slurry is mixed in, and then making paper without stirring the slurry excessively.

A second tank will be installed. Then, the slurry introduction pipe from the first tank is connected to one end in the filter width direction of the Tux,
The slurry introduction pipe from the second tank is connected to the other end of the filter in the filter width direction. If the filter is made like this, the film containing large-diameter fibers will increase at one end in the filter width direction and the content of small-diameter fibers will increase at the other end in the filter width direction when the flow is between two and three. Without excessively stirring the slurry in Flozex (filter J), if the VC overflows and is then dehydrated using a suction device, one end in the width direction of the filter has many thick E-hill fibers, and the other end On the side, a mat with many small diameter fibers is obtained. Note that other specific settings of papermaking conditions and various treatments such as drying and cutting after papermaking may be carried out in accordance with ordinary methods for manufacturing glass fiber separators.
