INDUSTRIAL APPLICATION FIELD The present invention relates to improving the formation efficiency of paste-type lead-acid batteries assembled using unconverted anode plates. Conventional technology When converting a lead-acid battery that has been assembled using unconverted electrode plates, dilute sulfuric acid of a certain specific gravity is injected into the lead-acid battery, and the dilute sulfuric acid is left to stand for a certain period of time to sufficiently penetrate the electrode plates. After that, a method is adopted in which a constant current is passed for a predetermined period of time, and the chemical formation process is completed after confirming that the specific gravity of the electrolytic solution and the battery terminal voltage have increased to a certain value. The problem that the invention seeks to solve. In this case, the amount of electrolyte in the battery should be calculated by taking into consideration the sulfuric acid released from the lead sulfate contained in the negative and negative electrode plates through oxidation and reduction during chemical formation, and the concentration of the electrolyte due to the electrolysis of water that occurs at the end of chemical formation. The specific gravity of the electrolytic solution to be injected into the battery is also determined, but unless a step is taken to replace the electrolytic solution during formation, formation will have to be performed using dilute sulfuric acid (1.180 to 1.220), which has a high specific gravity value. In chemical formation using dilute sulfuric acid with a high specific gravity value, the amount of lead sulfate produced in the unformed positive and negative electrode plates after electrolyte injection is as follows:
Compared to dilute sulfuric acid (1.050 to 1.150), which has a low specific gravity value, the amount of lead sulfate increases significantly, and the amount of lead sulfate, which has poor conductivity, becomes large.As a result, the chemical formation efficiency with respect to the amount of electricity applied becomes poor, so a large amount of electricity is required. do. Further, after completion of chemical formation, unformed white lead sulfate tends to remain on the surface of the anode plate, particularly in the central part of the squares of the lattice substrate, resulting in disadvantages such as deterioration of battery performance and poor appearance of the battery. A means to solve a problem. The present invention eliminates the above-mentioned drawbacks,
After filling a lead or lead alloy grid substrate with a paste made by kneading PbO (lead oxide) powder with dilute sulfuric acid,
After assembling an unformed anode plate made by adhering Pb 3 O 4 (redundant) powder into a battery, chemical conversion is performed. Effect In the formation of the above assembled battery, even when using dilute sulfuric acid (1.180 to 1.200) with a high specific gravity value, the lead present on the surface of the center of the square of the grid substrate in the unconverted anode plate is removed when the electrolyte is poured into the battery. Red reacts with sulfuric acid to form lead dioxide, which has good conductivity, and at the same time, it mixes with lead sulfate, which has poor conductivity, that forms in the center of the squares of the grid substrate in the unconverted anode plate, resulting in the formation of lead dioxide formed from red lead. Lead becomes the core and the chemical conversion efficiency improves. Examples Next, examples of the present invention will be described. Pb 3 O 4 powder (lead 3) to obtain an unconverted anode plate 4. When forming a lead-acid battery assembled using the unconverted anode plate 4, dilute sulfuric acid (1.180
~1.200), it is possible to improve the chemical formation efficiency and reduce the amount of electricity applied, and furthermore, there is no residual white lead sulfate on the surface of the center of the squares of the grid substrate 1 in the anode plate after the chemical formation is completed. , it is possible to improve the battery performance without impairing the appearance of the battery. Next, as explained in Table 1, lead is assembled using an unconverted anode plate obtained by filling a grid substrate made of lead or lead alloy with a paste obtained by kneading conventional lead oxide with dilute sulfuric acid. The amount of electricity (300% of the battery's nominal capacity) during storage battery chemical formation (dilute sulfuric acid specific gravity 1.180 to 1.200, chemical liquid temperature 40°C) is 100%.
The battery capacity in that case is shown as 100. Simply reducing the amount of electricity supplied by conventional methods by 20% will result in the first
As is clear from the table, the amount of residual lead sulfate in the anode plate increases two to three times, which adversely affects the battery appearance and battery performance, such as decreasing battery capacity. On the other hand, chemical conversion of lead-acid batteries assembled using unconverted anode plates according to the present invention (dilute sulfuric acid specific gravity 1.180~
1.200, chemical liquid temperature: 40℃), if the amount of electricity to be energized is reduced to 80% or 70% of that of conventional batteries, the battery capacity at that time is almost the same as that of conventional lead-acid batteries, as shown in Table 1. . Moreover, the amount of residual acid lead in the anode plate is significantly reduced compared to conventional lead-acid batteries. Even in the case of formation using dilute sulfuric acid (1.180 to 1.200), which has a high specific gravity value, when pouring the electrolyte, the red lead 3 provided on the surface of the center of the square of the grid substrate 1 on the unformed anode plate becomes sulfuric acid. It reacts to form lead dioxide, which has good conductivity, and at the same time it mixes with lead sulfate, which has poor conductivity, which is generated in the unconverted anode plate, and the lead dioxide formed from the red lead layer becomes the nucleus. This seems to be due to improved chemical conversion efficiency. It is known that the above red lead 3 reacts with dilute sulfuric acid as described below.
