The present invention relates to an improvement in a method for manufacturing an air electrode used in an air battery. Conventional methods for manufacturing air electrodes use catalysts such as metal phthalocyanine to enhance the oxygen reduction ability of activated carbon, etc. However, metal phthalocyanine is insoluble in water, so it cannot be dissolved in organic solvents such as quinoline until it becomes saturated. It was produced by immersing activated carbon in this solution, pulling it up and drying it, scattering the organic solvent and depositing the catalyst on the surface of the activated carbon. Metal phthalocyanines are generally used as pigments and are insoluble in most liquids, soluble only in a limited number of organic solvents such as quinoline, NN-dimethylformamide, and α-chlornaphthalene. The amount dissolved was very small, and only 1 to 2% of the weight of the solvent was dissolved. Therefore, in order to deposit an effective amount of catalyst on activated carbon, it is necessary to impregnate the activated carbon with a solution, evaporate the solvent, and dry it.
The process up to the precipitation of the catalyst had to be repeated about eight times, making it a very laborious and time-consuming manufacturing method. In addition, these organic solvents are generally highly harmful to the human body, and in order to evaporate and scatter them, it is necessary to use equipment that is sufficiently expensive for safety reasons, and has disadvantages in manufacturing equipment and the like. Furthermore, it has been considered to improve the workload of electrode production and to solve health and safety problems by using metal phthalocyanine having a sulfon group and making it soluble in water. That is, metal phthalocyanine is treated with fuming sulfuric acid under heating to introduce a sulfon group into the outer benzene ring of the phthalocyanine ring, making it soluble in water, and heating it in coexistence with a carbon material to produce an air electrode. , no harmful organic solvents were used, and the process was improved. However, with this production method, if the conditions during the reaction with fuming sulfuric acid change slightly, the number of sulfon groups introduced will change significantly, resulting in differences in solubility in water, coexistence with carbon will not be microscopically uniform, and air The drawback was that the characteristics of the electrodes varied. The present invention aims to improve the drawbacks of the conventional method by adding metal powder to sulfonated ammonium phthalate and further neutralizing it to form a sulfonated metal phthalocyanine salt to produce an air electrode. Examples of the manufacturing method of the present invention will be described. In the present invention, first, 20 g of tri-ammonium 4-sulfophthalate, 1.2 g of copper powder, 30 g of urea, and 35 g of water are placed in a hard conical beaker, heated while uniformly mixed, and kept at about 210°C to carry out the reaction. After cooling, a slightly acidic aqueous solution is formed. Copper phthalocyanine tetra-4 made from the sulfonated ammonium phthalate produced by adding 10 to 20 c.c. of a saturated solution of ammonium chloride to this solution and heating it.
In an aqueous solution containing ammonium sulfonate salt,
Activated carbon particles of 25 μm or less are soaked and adsorbed from an aqueous solution to 10% by weight of the activated carbon, then dried and heated at 300°C to 1300°C in an inert gas atmosphere such as nitrogen gas. The air electrode is manufactured by adding PTFE to the heat-treated product in an amount of about 60 parts by weight of activated carbon and 40 parts by weight of polytetrafluoroethylene (PTFE). The metal phthalocyanine having a sulfon group used in the present invention is made from sulfonated phthalic acid. Therefore, four hydrophilic sulfon groups (-SO 3 Furthermore, it coexists evenly with activated carbon on a microscopic level. This is because when using fuming sulfuric acid, the number of sulfon groups varied between 1 and 4 depending on the reaction conditions, whereas in the present invention, phthalic acid, which has already been sulfonated, is used as a raw material. All of the metal salts of sulfonated phthalocyanine produced have four sulfon groups in their outer shells. Therefore, since the solubility in an aqueous solution is always constant, an aqueous solution with a uniform concentration can be obtained.For this reason, when an aqueous solution and activated carbon are mixed and adsorbed on the activated carbon, it is possible to always adsorb in a uniform dissolved state. The effects of solubility fluctuations are eliminated. That is, it is possible to manufacture an air electrode with extremely high reliability in terms of work management and stabilization of the quality of batteries using the air electrode. The sulfonated phthalate used as a raw material is ammonium salt C 6 H 3 (CO 2 NH 4 ) 2 .
In addition to SO 3 NH 4 , potassium salts, magnesium salts, sodium salts, barium salts, strontium salts, etc. can be used. In addition to copper, metal salts include nickel,
Similar results can be obtained using sulfonated metal phthalocyanine salts formed using transition metals such as iron, cobalt, and ruthenium. A button-type air cell using an air electrode according to an embodiment of the present invention will be explained based on the drawings. Reference numeral 1 denotes a positive electrode can that also serves as a positive electrode terminal, and has an air supply hole 2 at the bottom. 3 is an air electrode which is in contact with a lyophilic semipermeable membrane 4. Reference numeral 5 denotes an electrolyte holding layer holding a caustic alkaline electrolyte, which is a nonwoven fabric or porous material with excellent liquid retention and liquid resistance, and is in contact with the negative electrode body 6 . 7 is an air diffusion paper with good permeability, which is in contact with the air electrode via a PTFE sheet 8 having many micropores, and the other side is in contact with the bottom of the positive electrode can 1 where the air supply holes 2 are provided. . Reference numeral 9 denotes a negative electrode can, and the opening of the positive electrode can 1 is bent through a gasket 10 to seal the battery. Next, a button-type air battery using the air electrode of the present invention will be compared with a conventional battery. The product of the present invention [A], which is an air battery with a diameter of 11.6 mm and a height of 5.4 mm, and a conventional product of the same type [B] that uses metal phthalocyanine made of fuming sulfuric acid, 100 each, were made into 25

This is because all the metal salts of sulfonated phthalocyanine used in the products of the present invention have four sulfon groups in their outer shells. As described above, an air battery having an air electrode using a catalyst of a sulfonated metal phthalocyanine salt produced from sulfonated ammonium phthalate of the present invention has excellent discharge performance.
