Abstract

PURPOSE:To obtain an easily assembled maintenance-free battery having excellent life span and shows least reduction of electrolyte by providing a separator consisting of glass fiber and high water absorbing resin between the negative and positive plates. CONSTITUTION:A separator used is formed by spraying a high water absorbing resin 2 of the starch, cellulose, polyacrylic acid, poval or polyoxyethylene system into glass fiber 1. Since the high water absorbing resin 2 shows excellent liquid absorbing property and expands when it absorbs liquid, close contactness between the positive and negative plates can be obtained. Thereby, a maintenance- free sealed lead storage battery which shows excellent life span characteristic, least reduction of electrolyte during operation and gas absorbing characteristic can be obtained.

すい欠点もある。In this type of lead-acid battery, it is preferable that the electrolyte-impregnated glass mantle and the cathode and anode plates are in uniform contact with each other, so during manufacturing, pressure is applied to these electrode plates, but when they absorb the electrolyte, Because the repulsive force of the glass mat decreases,
Another drawback is that the uniform adhesion between the glass mat and the negative and anode plates is easily impaired.

It is characterized by the use of a separator made of a polyacrylic acid-based, poval-based, or polyoxyethylene-based superabsorbent resin sprinkled with it.The superabsorbent resin has excellent liquid absorption properties and swells if it still absorbs liquid. Therefore, it is possible to improve the adhesion between the negative and anode plates.
