Abstract

PURPOSE:To improve the performance of a lead storage battery by using a separator made by fusing a net-like synthetic resin separator, a sheet-like synthetic resin separator and a mat-like synthetic fiber separator. CONSTITUTION:After a mat-like synthetic fiber separator 3 such as a polyethylene fiber separator is placed between a net-like synthetic resin separator 1 such as a polyethylene separator and a sheet-like porous synthetic resin separator 2, e thus stacked sheets are fused by ultrasonic wave to make a separator 4. Thus made separators are then placed between a positive plate 5 and two negative plates 6 in such a manner as to bring the separators 2 into contact with the negative plates 6. Because of the above structure, the liquid diffusion and the degassing of the positive plate 5 are improved, any separation of the active material is prevented by the separator 3 and any through short is prevented by the separator 2.

採用さ几ている。Conventional technology In order to extend the life of conventional lead-acid batteries, it is essential to prevent the positive electrode active material from becoming muddy and falling off. Therefore, it is effective to apply K to the active material as evenly as possible. It is believed that it is. Therefore, we added a lip to the separator,
Measures have been taken to improve the density of glass fibers in separators with glass mats, and to make separators with multi-metal structures.

量面で電池性能を低下させる欠点を有している。Problems that the invention aims to solve However, with such a separator, it is not possible to apply even pressure to the raw material, and even if it can be applied evenly, it is too close to each other, making it difficult for sulfuric acid to diffuse and outgas, and the capacity is reduced. However, it has the disadvantage of deteriorating battery performance.

よって電解液の拡散・ガス抜けを良好ならしめる。Compared to conventional separators, the action separator is able to press the active material more three-dimensionally and prevent it from falling off, and the mat-like synthetic fiber separator makes it possible to maintain a sufficient base of sulfuric acid. The net-like synthetic resin separator allows for good electrolyte diffusion and gas release.
