[Technical Field of the Invention] The present invention relates to a method for manufacturing an alkaline battery using a gelled zinc cathode active material. [Prior art of the invention and its problems] In an alkaline battery using a gel-like zinc cathode active material made by kneading zinc powder and an alkaline electrolyte,
It is known that battery characteristics are greatly affected by the zinc cathode manufacturing process. BACKGROUND ART Conventionally, a method is known in which a zinc cathode active material is produced by dispersing zinc powder in an alkaline electrolyte that has been previously formed into a gel. However, with this method, the zinc powder settles due to uneven gravity of the zinc powder during battery storage, resulting in a significant decrease in reaction efficiency as a zinc cathode. In addition, with this method, it is difficult to accurately fill the negative electrode container with a predetermined amount of zinc powder, and especially in the case of small batteries, there is a large variation in the amount of zinc powder filled. It was difficult to balance the capacitance of the cathode. On the other hand, in order to reduce variations in battery discharge performance, a predetermined amount of mixed powder mainly consisting of zinc powder and glue is weighed out and filled into a cathode container, and then an alkaline electrolyte is poured into the gelled zinc powder. There are methods for producing cathode active materials. However, with this method, the fluidity of the mixed powder is not very good, so the weighing accuracy decreases, and the dispersion of the paste becomes uneven during the filling process into the cathode container, which may deteriorate the battery characteristics. be. [Object of the Invention] This invention was made to solve the above-mentioned problems, and its purpose is to provide a method for manufacturing an alkaline battery that can improve the accuracy of weighing zinc powder and improve the battery characteristics. . [Summary of the Invention] This invention involves attaching carbon fluoride to the surface of a mixed powder mainly consisting of zinc powder to increase the fluidity of the mixed powder, and then injecting an alkaline electrolyte into the mixed powder to form a gel. The method is characterized by producing zinc cathode active material. [Effects of the Invention] According to the present invention, by attaching carbon fluoride to the surface of a mixed powder mainly containing zinc powder to reduce the frictional resistance between the mixed powder, the fluidity of the mixed powder is improved and zinc Powder weighing accuracy can be significantly improved. Furthermore, by dispersing carbon fluoride in the gelled zinc cathode active material to increase electrical conductivity, discharge performance under heavy loads and at low temperatures can be improved. [Embodiment of the Invention] An embodiment of the invention will be described below with reference to the drawings. First, the structure of the alkaline battery obtained by the present invention will be described. In the attached drawings, reference numeral 1 denotes a metal container made of nickel-plated iron that also serves as an anode terminal, and the bottom of this container 1 is coated with silver oxide (AgO,
An anode mixture molded body 2 containing AgO 2 ) or manganese dioxide (MnO 2 ) as an anode active material is filled. Further, on the anode mixture molded body 2, a separator 4 made of a 0.1 mm thick microporous polyethylene laminated with cellophane on both sides and a nonwoven fabric 5 made of rayon are disposed. 6 is a sealing plate made of an iron plate with copper on the inner surface and nickel plating on the outer surface, which also serves as a cathode terminal. Inside this sealing plate 6, a gelled zinc cathode active material is prepared by kneading a gelling agent powder such as sodium polyacrylate or carboxymethyl cellulose, an alkaline electrolyte made of caustic potash or caustic soda, and zinc chloride powder. 7 is filled. Then, an insulating packing 8 is fitted onto the peripheral edge 6a of the sealing plate 6, and the opening 1a of the outer container 1 is bent inward and tightened to form a battery. In this case, in the manufacturing process of the alkaline battery constructed as described above, the gelled sub-acute cathode active material 7 is manufactured according to the following steps. First, the cathode active material 7 was prepared using 10% by weight zinc chloride powder (48% by weight).
~100 mesh) is mixed with a dispersant such as magnesium oxide or titanium oxide, and a thickener such as sodium polyacrylate powder, and the mixed powder is heated to a humidity of 60%.
The mixed powder is stabilized by being left in the atmosphere for 15 hours and subjected to humidification treatment. Thereafter, carbon fluoride is added to and mixed with the mixed powder, and the mixture is stabilized by being subjected to a humidification treatment in the same manner as described above. A predetermined amount (for one battery) of this mixed powder mainly composed of zinc powder is weighed out and inserted into the sealing plate 6. At this time, the method of weighing the mixed powder is to place a battery under the hopper that stores the mixed powder.
An opening/closing sliding plate is provided in which a hole having a volume corresponding to that of the powder is formed, and the mixed powder is filled from a hopper into the opening of this sliding plate. Thereafter, excess mixed powder is scraped off using a scraper plate to make the volume of the mixed powder filled in the holes constant. In this state, slide the opening/closing sliding plate to align the hole with the prepared hole. Then, the mixed powder filled in the hole passes through the lower hole to the sealing plate 6 located below.
is inserted into. Finally, a gelled zinc cathode active material 7 is formed by pouring 26% by weight of caustic soda in which zinc oxide is dissolved into the mixed powder. Therefore, by adding and mixing carbon fluoride to a mixed powder mainly consisting of zinc fluoride powder, the carbon fluoride is uniformly adhered to the surface of the mixed powder. In this way, by reducing the frictional resistance between the mixed powders and increasing the fluidity of the mixed powders, it becomes difficult for the mixed powders to adhere to the opening/closing sliding plates and scraping plates.
It is possible to significantly improve weighing accuracy, and
Flow within the hopper can be improved to prevent blockage and bridging. Further, by dispersing carbon fluoride, the electrical conductivity of the gelled zinc cathode active material 7 can be increased, so that the discharge performance under heavy loads and at low temperatures can be improved. Therefore, as a specific example, the product (A) of the present invention is a silver oxide alkaline battery SR920 filled with the cathode active material 7 manufactured according to the present invention, and an alkaline electrolyte is poured into a mixed powder mainly consisting of zinc powder. The following items were compared with a conventional product (B) filled with a cathode active material produced by liquid preparation. (1) The accuracy of weighing the zinc mixed powder with respect to the average weight (X) of 65 mg was investigated, and the results shown in Table 1 were obtained.
