トを陰。Prior Art and its Problems Conventionally, a substantially non-fluidized dilute sulfuric acid electrolyte has been used as the electrolyte for sealed lead-acid batteries. The method for making the electrolyte non-fluid is to use a highly liquid-absorbing fine glass fiber mat mainly made of glass fibers with a diameter of 1 mm or less.

There are methods that use electrolytes, methods that use a combination of a fine glass fiber mat and a gel electrolyte, and the like. However, the above-mentioned fine glass fiber mat is expensive, and the gel electrolyte has drawbacks in that it is difficult to uniformly inject the gel electrolyte into the battery.

得られた。EXAMPLE First, a separator is formed from a woven or nonwoven fabric made by blending polyethylene fibers, which are acid-resistant resin fibers, and sodium polyacrylate fibers, which are liquid-absorbing resin fibers. Thereafter, the seven separators are placed between the negative and anode plates and inserted into the battery case in a conventional manner, and then the separators are impregnated with a dilute sulfuric acid electrolyte. In general, sodium polyacrylate fibers are highly absorbent and exhibit the behavior of a polymer electrolyte in an aqueous solution such as a dilute sulfuric acid electrolyte. Therefore, when the separator is impregnated with a dilute sulfuric acid electrolyte, the polyacrylic acid fibers contained in the separator are dissolved and the dilute sulfuric acid electrolyte is gelled. By the above method, a sealed lead-acid battery of the present invention having a dilute sulfuric acid electrolyte that is substantially non-fluidized is completed. In addition, similar effects were obtained when carboxymethyl cellulose was used as the absorbent resin fiber in addition to the above.

の怜舟粉来が得られた。Figure 1 shows the number of alternate charging and discharging cycles of the storage battery of the present invention and the polyacrylic acid contained in the separator.
FIG. When the proportion of sodium polyacrylate fibers is 20 weight 1% vermilion, the ability to gel the electrolyte is small and the life is short; when it exceeds 80 weight %, the gas absorption capacity is reduced and the life is also short. Therefore, the appropriate proportion of sodium polyacrylate fiber is 20 to 80% by weight. In addition, even when carboxymethyl heptyl-4-se was used as the liquid-absorbing resin fiber, a similar product was obtained.

井倍果が得られた。FIG. 2 is a diagram showing the relationship between the number of alternate charging and discharging lifetimes of the storage battery of the present invention and the thickness of the seven pallets used in FIG. If the thickness of the pallet is less than 5 cm, the required amount of electrolyte cannot be held and the life will be short; if it exceeds 3111F, the gas permeability will be poor and the life will be short. Therefore, the thickness of the separator is Q,
5 to 3 gates is appropriate. Note that similar results were obtained even when carboxymethyl cellulose was used as the liquid-absorbing resin fiber.
また、上記実施例に使用した極板はペースト式であるが

る。Further, although the electrode plates used in the above embodiments are of a paste type, the present invention can also be used in storage batteries using clad type electrode plates.
発明の効果
本発明は特許請求の範囲に記載した通りの構成であり、
高価な微細ガラス繊維マットを使用しないため蓄電池の
コストダウンを実現できる。Effects of the invention The present invention has the configuration as described in the claims,
Since expensive fine glass fiber mats are not used, the cost of storage batteries can be reduced.
マタ、セパレータ中の吸液性樹脂繊維がゲル化剤として
作用するため、電槽内で容易に電解液をゲル化できる。Since the liquid-absorbing resin fibers in the separator act as a gelling agent, the electrolyte can be easily gelled within the battery container.
更に前記吸液性樹脂繊維はセパレータ中に均一に含まれ
ており、電槽内で電解液を均一にゲル化できるため、電
解液の偏在がなく蓄電池の寿命性能が向上する。Furthermore, since the liquid-absorbing resin fibers are uniformly contained in the separator and the electrolyte can be uniformly gelled within the battery case, the electrolyte is not unevenly distributed and the life performance of the storage battery is improved.
