[Technical Field of the Invention] This invention relates to a method for manufacturing an alkaline battery using an improved gelled zinc cathode. [Technical background of the invention and its problems] Conventionally, in an alkaline battery that uses a gelled zinc cathode formed by kneading zinc powder, an alkaline electrolyte, and a paste, zinc is mixed into a gelled alkaline electrolyte. A gelled zinc cathode was obtained by dispersing the powder. However, the zinc cathode obtained by such a method has the drawback of low accuracy in weighing. Therefore, recently, JP-A-57-60660 and JP-A-Sho
As shown in No. 57-60661, a method of forming a gelled zinc cathode by first weighing out a mixed powder of zinc powder and a paste and then pouring an alkaline electrolyte into it has come to be used. However, in gelled zinc cathodes that are not kneaded, the zinc powder is not uniformly dispersed, and the surface of the zinc powder is not sufficiently wetted, resulting in low activity. Furthermore, there were drawbacks such as shortening of battery life. [Object of the Invention] The present invention eliminates the above-mentioned drawbacks, and provides an alkaline battery that improves the discharge performance under heavy loads and low temperatures, has a large initial capacity, has a long shelf life, and has uniform performance. The purpose is to provide a manufacturing method. [Summary of the Invention] The present invention involves weighing out a predetermined amount of a mixed powder of zinc hydroxide and an amount of glue, and adding Na to it when producing an alkaline battery.
-di-n-octyl sulfocinate or
It is characterized by the use of a zinc cathode obtained by injecting an alkaline electrolyte containing Na-dinonylnaphthalene sulfonate. [Effects of the Invention] The gelled zinc cathode used in the present invention contains a surfactant, Na-di-n-, in an alkaline electrolyte.
Contains octyl sulfosuccinate or Na-dinonylnaphthalene sulfonate,
The zinc chloride powder is uniformly and stably dispersed, has increased affinity with the electrolyte, and can assist in the diffusion of discharge products. Therefore, the discharge performance of the battery under heavy loads and low temperatures can be improved and the initial capacity can be increased. In addition, since the electrolyte contains a surfactant, the moisture in the electrolyte can be prevented from evaporating into the air during the period between injection of the electrolyte and fitting with the anode. It is possible to measure the uniformity of
Therefore, it has the advantage of equalizing each performance of the battery and extending its shelf life. [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described in the case of a button-type alkaline battery with reference to the drawings. In the attached drawings, reference numeral 1 denotes a metal outer container made of nickel-plated iron that also serves as an anode terminal, and a mixture molded body 2 containing oxygen silver (AgO, Ag 2 O) or manganese dioxide (MnO 2 ) as an anode active material. Fill it tightly against the inner wall. Next, a separator 3 is placed on top of the mixture molded body 2. This separator 3 is made of, for example, 0.1 mm thick microporous polyethylene with cellophane laminated on both sides. Nonwoven fabric 4 made of rayon on separator 3
Further, a gelled zinc cathode 5 made of an alkaline electrolyte is disposed above the cathode. Reference numeral 6 denotes 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.Insulating packing 7 is fitted around the periphery of the sealing plate, and the opening 8 of the metal outer container 1 is bent inward and tightened. This completes the battery. The above-mentioned gelled zinc electrode 5 is made by mixing 100 g of 10% by weight zinc chloride powder of 48 to 100 meshes with 5 g of sodium polyacrylate powder as a glue, and weighing out a predetermined amount equivalent to one battery. 26% by weight caustic soda solution containing 0.02% by weight Na-di-n-octyl sulfosuccinate or Na-dinonylnaphthalene sulfonate and dissolved zinc oxide was poured into the sealing plate 6 which also served as a cathode terminal. It is formed by The performance of the thus obtained button-type silver oxide alkaline battery [A] according to the present invention and a conventional battery of the same type that does not contain a surfactant [B] is as follows. Table 1 shows the closed-circuit voltage after 5 seconds of 2KΩ constant resistance discharge at −10° C. for different depths of discharge: 0%, 40%, and 80%. Table 2 also shows the duration up to 1.2V in 20KΩ constant resistance discharge at 20°C.
Furthermore, Table 3 shows the results of storage at 60℃ [A]
[B] Both are 100% immediately after production, 20, 30, 40,
It shows the sustainability rate [%] of the discharge capacity until it reaches 1.2V when the battery is discharged at 20℃ and 30KΩ after being stored for one day. Note that the number of test batteries for obtaining these data was five for both [A] and [B].
