【発明の詳細な説明】
本発明は鉛蓄電池用正極板の製造法の改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the manufacturing method of a positive electrode plate for a lead-acid battery.
従来鉛蓄電池用正極板は、化成、水洗後乾燥まての間は
室温中に放置状態であつた。Conventionally, positive electrode plates for lead-acid batteries have been left at room temperature until drying after chemical formation and water washing.
この場合、特に夏季においては雰囲気の温度が上昇し、
水や硫酸の影響て卯用式正極板ては格子と活物質の間に

極板の化成、水洗後乾燥まての間に保管温度を常に１５
℃以下に保つて、正極活物質と格子と水や硫酸との反応

るものである。In this case, the temperature of the atmosphere increases, especially in summer,
Under the influence of water and sulfuric acid, resistors such as lead hydroxide and lead sulfate are formed between the lattice and the active material in the rabbit-type positive electrode plate, which deteriorates the performance of the rabbit-type positive electrode plate. In view of the above-mentioned points, the present invention maintains a storage temperature of 15% during the formation of the positive electrode plate, washing with water, and drying.
By keeping the temperature below °C, the reaction between the positive electrode active material, the lattice, and water or sulfuric acid is suppressed, and the deterioration of the positive electrode plate during storage is prevented.
本発明の一実施例について説明する。An embodiment of the present invention will be described.

化するものが出てきて、卯月性能が劣化した。If the rabbit type positive electrode plate is kept at a temperature below 15°C during chemical formation, washing with water, and drying, there is almost no reaction with sulfuric acid, water, or carbon dioxide, but the storage temperature is 25
When the temperature exceeds ℃, the positive electrode active material (lead dioxide) and the lattice (metallic lead) react and change into lead oxide, lead sulfate, basic lead carbonate, lead hydroxide, etc., and the active material is also converted to sulfuric acid by residual sulfuric acid. Something that turned into lead appeared, and Uzuki's performance deteriorated.

業的価値甚だ大なるものである。Here, the 5th second voltage is the positive electrode plate 1 for NS4 square lead acid battery.
This is the voltage measured by Uzuki discharge at 0° C. and 3OA using two negative electrode plates as counter electrodes. Here, the one stored at 0'C did not deteriorate at all, indicating that water, one of the resistor products, was frozen and no production reaction occurred. It was also found that the Uzuki voltage decreased as the temperature rose and the storage time increased. As is clear from Figure 1, when the storage temperature is always kept below 15°C, almost no reaction occurs between water or sulfuric acid, the lattice, and the positive electrode active material.
It is possible to prevent deterioration of the initial performance of the Uzuki voltage of the electrode plate. In Figure 1, A is a storage temperature of 0°C, CNB is a storage temperature of 5°C, C is a storage temperature of 15°C, and D is a storage temperature of 25°C.
, E indicate the case where the storage temperature is 35°C. FIG. 2 also shows the storage temperature and storage time in vacuum (10-degrees Hg) and the Uzuki voltage at that time (5J second voltage). In this figure, A' is the storage temperature of 0°C, and B' is the storage temperature of 5°C.
, C' is storage temperature 15℃, D' is storage temperature 25℃, E'
1 and 2 respectively show the case where the storage temperature is 35°C. As is clear from this figure, even in vacuum (10-°7rgnHg), the deterioration phenomenon 7 of the positive electrode plate is rare when the storage temperature is kept below 15°C, and is more common at 25°C. As mentioned above, according to the present invention, by keeping the storage temperature of the positive electrode plate at 15°C or lower after chemical formation and washing with water until drying, it is possible to prevent deterioration of the positive electrode plate during storage, which has great industrial value. It is a big thing.
