摘要： PURPOSE:To provide a uniform electrolytic solution equipped with an intended specific gravity, which excels in the producibility, consumes less power, and is free from the risk of contaminating the environment, when an assembly lead acid battery not having undergone a chemical formation process having a sack-shaped separator is to be charged. CONSTITUTION:For charging, a low specific gravity sulphuric acid is poured in an assembly lead acid battery not having undergone a chemical formation process having a sack-shaped separator, and then the specific gravity of the electrolytic solution is adjusted by the use of sulpburic acid having a high specific gravity, wherein the high specific gravity sulphuric acid is poured in at a low speed of below 100ml/min while current is fed with a current density over 25mA/cm . Thereby a uniform electrolytic solution ran be prepared in a short time.

摘要： PURPOSE:To provide lead powder having a high degree of oxidation and enhance battery performance such as the life of a battery by manufacturing lead powder of a degree of oxidation 50-70% using ball-mill method, and then adding water by 3-7% to the lead powder, and stirring the powder. CONSTITUTION:The speed of oxidation is at its maximum when the amount of water added is 3-7% otherwise the speed of oxidation is decreased whether the amount of water added is smaller or larger than that. Water is added by 5% to lead powders of a degree of oxidation 70% fabricated by ball-mill method and then the powders are stirred for thirty minutes, and then the lead powders which are thereby made to have a degree of oxidation 98% are used to fabricate a battery having an official capacity of 27Ah and the battery is subjected to a SAE life test together with conventional batteries and the result is shown in Figure. Figure shows that while the battery is such a stable one as to be durable for 8000 times of discharge, conventional ones have a shorter life and shows large dispersion in the number of times of discharge. This does not indicate that lead hydroxide is generated by addition of water, but that R-Pb0 is generated and that the oxidation reaction of Pb is accelerated by help of water serving as a catalyst. Uniform lead powder having a high degree of oxidation can be manufactured in a short time and battery performance can be enhanced.

摘要： PURPOSE:To manufacture a lead storage battery plate whose active material hardly falls off. CONSTITUTION:Lead oxide (lead powder), which is mainly composed of lead monoxide, and dilute sulfuric acid are kneaded so that the lead oxide and the dilute sulfuric acid react with each other, and thereafter 1N of NaOH solution is added and is further kneaded so as to form active material paste. The active material paste is applied to a grid body being a collector so as to form a plate to be hardened, and the plate to be hardened is left in 0.1 percentage by weight of CO2 atmosphere for six hours so as to aging dry. Thereby it is possible to deposit the lead monoxide enough so that the active material hardly falls off.

摘要： PURPOSE:To efficiently agitate electrolytes in a short time by inverting a freely flowing electrolyte for the purpose of mixture, followed by gassing, whereby a non-freely flowing electrolyte and the freely flowing electrolyte pass through a separator, for substitution and agitation. CONSTITUTION:Sulfuric acid of a low concentration is injected into a separator type lead-acid battery, which can be chemically converted. The sulfuric acid of a low concentration is discharged while sulfuric acid of a high concentration is injected. When the sulfuric acid of a high concentration is injected into a battery jar 1, an electrolyte flowing inside the battery jar 1 is laminated in a high concentration region 2 and a low concentration region. The battery is inverted. Accordingly, the electrolyte flowing inside the battery jar (i.e., a freely flowing electrolyte) can be mixed. Although the freely flowing electrolyte outside of a separator is agitated when the battery is inverted to the original state, active substance and an electrolyte intruding into a pore formed inside of the separator (i.e., a non-freely flowing electrolyte) cannot be sufficiently mixed with the freely flowing electrolyte. (Consequently, a current is supplied to the battery for the purpose of gassing so that the non-freely flowing electrolyte and the freely flowing electrolyte pass through the separator, followed by agitation.

摘要： PURPOSE:To efficiently adjust the specific gravity of an electrolyte and uniformly mix the electrolyte of a lead-acid battery completed with battery jar formation by atomizing and injecting the specific gravity adjusting high-concentration sulfuric acid into the battery. CONSTITUTION:A lead-acid battery 1 assembled with an electrode plate group constituted of unformed electrode plates stored in a bag-like separator is formed in a battery jar. Part of the low-specific gravity electrolyte used for formation is released, or the battery 1 is tilted and rocked to the right and left in turn from the horizontal state without releasing the electrolyte, and specific gravity adjusting high-concentration sulfuric acid is atomized and injected into the battery 1. The battery 1 is excited to generate gas, and the electrolyte is stirred by bubbles. The high-concentration sulfuric acid is prevented from being accumulated at the bottom section of the battery 1 into a lump shape, and the electrolyte can be mixed in a short time by the rocking action. The specific gravity of the electrolyte of the battery 1 completed with battery jar formation can be efficiently adjusted, and the electrode can be uniformly mixed in a short time.

摘要： PURPOSE:To facilitate gas separation within a sack-shaped separator and allow intruding electrolytic solution to well diffuse by furnishing a welded and an unwelded portion when the bottom and the two sides of the separator are shut while certain gaps are reserved at these parts of the separator, and dislocating the mating surfaces of the welded and unwelded portions at the ends from each other. CONSTITUTION:At the bottom and the two ends of a sack-shaped separator 1 made of polyethylene etc., a welded portion 2 not admitting intrusion of electrolytic solution and an unwelded portion 3 admitting coming in/out of the electrolytic solution are furnished while a gap between 2-10mum is reserved. The mating surfaces of the welded 2' and unwelded 3' portions at the ends are dislocated from each other and the gaps provided in these places enable the electrolytic solution to anywhere intrude into and come out of the separator 1. An electrode plate 4 having a protruding tab 5 is sunk where this separator 1 is arranged, which eliminates risk of shortcirctuiting of the electrode plate 4.
