による乾燥方式等で行っていた。[Prior art] In the conventional manufacturing method of this type of electrode plate, a paste is prepared by kneading an active material with a binder and a solvent into a porous metal core material (hereinafter referred to as core material) made of nickel-plated iron. After the active material was applied to form the electrode plate, the electrode plate was dried in a drying process. In this drying process, the water and solvent used to produce the paste-like active material are dried, using a hot air exhaust drying method in which hot air is applied to the electrode plate and then exhausted, for example, using far infrared rays. This was done using a drying method, a drying method using hot air supply, etc.

があった。[Problems to be Solved by the Invention] However, in the VJ manufacturing method for electrode plates for sealed alkaline storage batteries in which the electrode plates are manufactured by drying as described above, hot air exhaust drying is performed to shorten the drying time. When the solvent evaporates from the applied paste-like active material, it evaporates rapidly, so the passage for the solvent to be removed from and exiting the paste-like active material is biased toward the electrode plate, and after drying, the electrode plate does not remain. There was a problem in that vent holes were uniformly formed and the oxygen gas absorption performance of the active material was deteriorated.

風排気乾燥工程とからなっている。[Means for Solving the Problems] The present invention will be explained based on the embodiment shown in the drawings. An active material 1 in the form of a slurry or paste active material is applied to a core material 4 to a predetermined thickness. In this method, the electrode plate 6 thus formed is sent to a drying process, and the active material of the electrode plate 6 is dried. The drying process includes a hot air circulation drying process in which the active material 10 is semi-dried while circulating hot air that is applied to the electrode plate 6, and a hot air circulation drying process in which the active material 10 is semi-dried while circulating hot air that is applied to the electrode plate 6.The hot air that is sent from the hot air circulation drying process and applied to the electrode plate 6 is applied to the electrode plate 6 and then exhausted. The process consists of a hot air exhaust drying process in which the active material 1 is completely dried while drying.

来と略変らないように短縮することができる。[Function] As described above, if the active material 10 is semi-dried in the hot air circulation drying process while circulating the hot air applied to the electrode plate 6, there is no rapid evaporation of the solvent, and the electrode plate 6 is heated. Drying can be performed while forming uniform and fine ventilation holes without creating uneven ventilation holes at the top. In addition, if the electrode plate sent from the hot air circulation drying process is completely dried while the hot air is applied to the electrode plate 6 in the hot air exhaust drying process and then exhausted, the drying time is almost the same as in the conventional method. It can be shortened as follows.
