Abstract

PURPOSE:To prevent generation of cracks in gelled electrolyte by pouring a mixture of a silicic acid aqueous solution having a specified concentration and suffuric acid solution in a battery and vibrating the battery for a specified time. CONSTITUTION:A mixture of a silicic acid aqueous solution having a specified concentration and sulfuric acid solution is poured in a battery 1. Then, vibration by which the silicic acid gel is converted into the sol by thixotropy is applied to the battery with a vibrator 2 so that the electrolyte is kept in a sol state while gas is evolved for a specified time during which gas in the battery is sufficiently removed. Thereby, generation of cracks of gel caused by gas is prevented, and oxygen gas evolved in charge is transferred to the whole area of an anode plate to uniformly conduct oxygen gas reducing reaction in the anode, and the early deterioration in active material caused by ununiform specific gravity distribution is prevented.

が抜けたことによる亀裂が生じる。Conventional Technology Conventionally, when a mixed solution of a silicic acid aqueous solution and a sulfuric acid solution is injected into a sealed lead-acid battery using a gel electrolyte, the mixed solution infiltrates into the pores of the separator, glass mat, electrode plate, etc. At this time, a large amount of gas is generated, but this gas is continuously generated during the gelation process of the mixed liquid, so by the time gelation has finished and gas generation has stopped, gas has escaped into the gel. Cracks occur due to this.

物質の早期劣化が起こるという問題か生じる。Problems to be Solved by the Invention Due to these cracks, oxygen gas generated during charging easily moves to the upper part of the electrode plate, and the reduction reaction of oxygen gas at the cathode tends to occur at the upper part of the cathode. As the life progresses beyond this point, the specific gravity becomes lower in the upper part and higher in the lower part, leading to the problem that early deterioration of the active material occurs in the lower part.

It is characterized by

By applying vibrations to the battery, the electrolyte remains in a sol state while gas is generated.

This allows the oxygen gas reduction reaction to occur uniformly at the cathode, thereby preventing early deterioration of the active material due to non-uniform specific gravity distribution.
