は、ガラスマットが非常に高価であるため、製造コスト
が上昇するという欠点があった。Prior art and its problems Conventionally, the main cause of the lifespan of lead-acid batteries was a decrease in the capacity of the positive electrode plate due to shedding of the positive electrode active material. Methods for preventing the cathode active material from falling off include: ■ Applying pressure of about 2019/(M) from both sides of the electrode group in which positive and negative electrode plates are laminated with a separator in between; ■ Increasing the packing density of the cathode active material. There is a method (1) in which an elastic glass mat is placed between the positive and negative electrode plates. However, method (2) requires a step of inserting the electrode group into the battery case while pressurizing it. The pressurized insertion process was a fairly difficult process in the entire manufacturing process.In addition, the method (■) had the drawbacks of poor high-rate discharge characteristics and inferior initial capacity.Furthermore, the method (■) Since the mat is very expensive, the manufacturing cost has increased.

First, it swells by absorbing sulfuric acid in an electrolytic solution, sulfuric acid aqueous solution.
A separator containing a polymeric material whose volume increases macroscopically is prepared. Next, after placing the separator between the positive and negative electrode plates to form an electrode group, the electrode group is inserted into the battery case without applying pressure, and then an aqueous sulfuric acid solution is injected. As the molecular material, for example, a linear aminated polyvinyl chloride obtained by substituting some of the hydrogen atoms of polyvinyl chloride μ with amino groups can be used. Aminated polyvinyl chloride has the ability to fix protons (hydrogen ions) at the amino group (-NH2) and adsorb anions (sulfate ions) between the straight polymer molecules.

あれば他の材料な月いてもよい。The polymer material used in the present invention is not limited to aminated polyvinyl chloride, but other materials may be used as long as they swell and increase their volume macroscopically by absorbing sulfuric acid. You can stay there.

ができる。As is clear from Table 1, when the separator used in the present invention absorbs sulfuric acid and swells, its volume increases macroscopically and its thickness increases by about 1.5 times. Furthermore, if sulfuric acid is absorbed while the thickness of the separator is fixed to approximately 1, a pressure of about 20 k (i/d!) can be generated. This pressure does not vary greatly depending on the specific gravity of the sulfuric acid aqueous solution. Therefore, there is no need to apply pressure when inserting the electrode group into the battery container, and the electrode group can be pressurized simply by injecting electrolyte after insertion.

Using this prototype battery, initial discharge characteristics (Figure 1) and changes in discharge capacity during cycle use (Figure 2) were measured. In addition, the initial discharge characteristics were shown by the voltage change when discharging at 25° C. and 1.03 A (3 hour rate). In addition, the discharge capacity change during cycle use is 75% of the rated capacity at 25°C and 1.03 μm (3 hour rate).
% discharge and charging at 125% of the discharge amount at 25° C. and 0.681 (5 hour rate) as one cycle, and the change in discharge capacity is shown when charging and discharging are repeated.

している。As is clear from FIGS. 1 and 2, the lead-acid battery manufactured by the method of the present invention exhibits characteristics that are almost the same as those of the lead-acid battery manufactured by the conventional method, both in terms of initial discharge characteristics and changes in discharge capacity during cycle use.

It may be formed by mixing or mixing.

の恐れを少なくできる。Further, in the above embodiment, an example was shown in which a nonwoven fabric was used as the separator, but the present invention is not limited to this. As another example, the separator may be a woven fabric or film mainly made of the above-mentioned polymeric material. It may also be formed from a sheet. When a film or sheet made of the above-mentioned polymer material is used as a separator, the film or sheet is non-porous, but when it absorbs sulfuric acid and swells, its volume increases macroscopically and it fills with the absorbed sulfuric acid. In other words, when the sulfate ions in the electrode plate are consumed by discharge and the concentration decreases, the sulfuric acid that was absorbed in the film or sheet is supplied to the electrode plate, and charging When the sulfate ions in the electrode plate increase and reach a high concentration, the sulfuric acid is absorbed into the film or sheet. Furthermore, since this film or sheet is non-porous, the possibility of short circuit between the positive and negative electrode plates can be reduced.

(6v) and the manufacturing time of each was measured. As a result, the manufacturing time of the lead-acid battery according to the method of the present invention was reduced by about 40% compared to the manufacturing time of the lead-acid battery according to the conventional method.
