Abstract

PURPOSE:To improve explosion-proof property of a sealed type lead-acid battery by filling a gelled sulfuric acid electrolyte in the space of the upper part of an electrode groop. CONSTITUTION:An electrode group 2 comprising cathode plates, anode plates, glass mats mainly consisting of glass fibers having less than about 1mu diameter, which hold a sulfuric acid electrolyte is accommodated in a container 1. The space of the upper part of the electrode groop partitioned by the container 1 and an inner cover 3 is filled with a gelled sulfuric acid electrolyte. Therefore, the sulfuric acid electrolyte containing in the electrode groop is not diluted, and explosion-proof property of a sealed type lead-acid battery is improved.

Description

【発明の詳細な説明】 本発明は防爆性を向上させた密閉形鉛電池に関するもの

て埋めたことを特徴とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealed lead-acid battery with improved explosion protection, and is characterized in that the space above the electrode group is filled with a gelled sulfuric acid electrolyte.

以下１本発明をその一実施例を示す第１図により詳細に
説明する。すなわち該図面において。Hereinafter, the present invention will be explained in detail with reference to FIG. 1 showing one embodiment thereof. That is, in the drawing.

１は電槽、２は電槽１に収納された極群であり。1 is a battery case, and 2 is a group of poles housed in the battery case 1.

陽極板と陰極板と硫酸電解液を保持する１維径１μ以下
