本発明は電解液にゲル状電解液を使用した密閉
形鉛蓄電池及びその製造方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sealed lead acid battery using a gel electrolyte as an electrolyte and a method for manufacturing the same.
（従来技術とその問題点）
電解液にゲル状電解液を使用した密閉形鉛蓄電
池は、過充電を行うと電解液中からH2Oが消失
する。このため過充電を極力抑えるように蓄電池

充、放電を繰り返すうち、次第にH2Oが消失さ
れ、ゲル状電解液にヒビ割れを生じて、遂には寿
命に達し、特にこの寿命が短かいという欠点があ
つた。(Prior art and its problems) When a sealed lead-acid battery that uses a gel electrolyte is overcharged, H 2 O disappears from the electrolyte. For this reason, although care is taken when maintaining storage batteries to minimize overcharging, as they are repeatedly charged and discharged, H 2 O gradually disappears, cracks occur in the gel electrolyte, and the battery eventually reaches the end of its lifespan. However, it had a particularly short lifespan.

を上記で準備した電槽へ注入しゲル化させた。(Example) As a product of the present invention, a product in which a group of 28Ah/5HR (2 cells) electrode plates was inserted into a battery case was prepared. On the other hand, a sol-like SiO 2 solution (product name:
A mixture of Snortex and dilute sulfuric acid was prepared. In addition, a water-absorbing organic molecule, acrylic acid-vinyl alcohol copolymer having a particle size of about 20 μm, was saturated with H 2 O. Next, when the electrolyte is in the form of a sol, the water-absorbing organic polymer saturated with H 2 O is added to the electrolyte in the form of a sol.
They were mixed by volume and dispersed. Thereafter, the electrolytic solution was poured into the battery container prepared above and gelatinized.
従来品としては上記ゾル状のスノーテツクスに
希硫酸を加えたものをそのまま電槽へ注入しゲル
化させたものを使用した。 As a conventional product, the above-mentioned sol-like snowtex mixed with dilute sulfuric acid was directly poured into a battery container to form a gel.

くするという効果を奏した。 In order to evaluate the products of the present invention, five completed batteries were made from each of the products of the present invention and the conventional product, and these were subjected to a JIS life test for automobile storage batteries under the same conditions to compare the two. The results are as shown in Figure 1, and the product of the present invention had an effect of extending the life by about 30% compared to the conventional product.
これは充、放電を繰り返すことによつて消失さ
れるH2Oが吸水性有機高分子に含浸したH2Oに
よつて補給されたものと考えられる。 This is thought to be because H 2 O, which is lost through repeated charging and discharging, is replenished by the H 2 O impregnated into the water-absorbing organic polymer.

ポリエチレンオキシド変成物を用いても良い。 In this example, acrylic acid was added to the water-absorbing organic polymer.
Although a vinyl alcohol copolymer was used, a sodium acrylate polymer or a modified polyethylene oxide may also be used.
