【発明の詳細な説明】 (産業上の利用分野) 本発明は密閉型鉛蓄電池に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a sealed lead acid battery.

する。(Prior art) Conventionally, in a sealed lead-acid battery, an active material is applied to the t-electrode substrate, and when assembling the fL female negative and positive electrodes, the distance between the two electrodes is maintained at a constant distance, and the electrolyte is spread across the electrodes. For this reason, it is common practice to interpose a glass plate as a separator between both electrodes.

の開発が望捷几てぃた。(Problem to be Solved by the Invention) However, the glass mat used as the separator of the sealed lead-acid battery absorbs the electrolyte and tends to shrink in thickness, and is relatively thick for both electrodes. Even if the electrode 1 is assembled with the insert 1 inserted between them in a compressed state and installed inside the electric housing, it is not possible to sufficiently prevent the formation of a gap between the electrode and the glass mat due to shrinkage of the glass mat. However, it does not adhere uniformly to the active material applied to the electrode substrate. Therefore, there are disadvantages such as the active material falling off from the electrode substrate, the electrolyte not being distributed uniformly to the active material, a decrease in battery capacity, and a shortened battery life due to a decrease in the gas absorption state. The goal was to develop a sealed lead-acid battery in which the electrolyte does not fall off and the electrolyte is evenly distributed over the active material.

に食込み状態に重会させた。In the figure, reference numeral 1 indicates an electrode substrate, and the electrode substrate is made of lead material, for example, and is made of lead alloy material and has a flat shape or a lattice shape. Reference numeral 2 indicates an active material, for example, a lead oxide material for an anode, and a sponge-like lead material for a cathode, and this active material 2 is applied to each electrode substrate 1. 3 indicates a glass mat, for example, a large number of thin single fibers with a diameter of about 0.5 to 20 microns obtained by melt-spinning acid-resistant alkali glass are crossed and overlapped and loosened. A porous sheet with a thickness of 0.2 to 4 layers was made so that the electrolytic solution could easily permeate therethrough, and was superimposed on the surface of the active material 2 so as to bite into the surface of the active material 2.

に重合させる。In order to apply the glass mat 3 to the electrode substrate 1 and superimpose it on the n'7 active material 2, apply the paste-like active material 2 to the electrode substrate 1, and apply the glass mat 3 while the active material 2 is soft. The glass mat 3'f-active material 2 is polymerized in a state where it bites into the glass mat 3'f-active material 2 by pasting it on the front and then drying and chemical conversion treatment.

ぎ寿命も長くなる。As mentioned above, the glass mat 3 is applied to the electrode substrate 1 and is polymerized in a state of biting into the surface of the active material 2.
Even if this glass mat 3 absorbs the electrolyte and shrinks, it will not separate from the electrode substrate 1, so that the electrolyte will always spread evenly over the active material 2 applied to both electrode substrates 1. Furthermore, the active material 2 applied to the electrode substrate 1 does not fall off, resulting in a good gas absorption state, preventing a decrease in battery capacity, and extending the service life.
