あった。Conventional technology and its problems In a liquid injection type battery, the electrolyte chamber and the electrode chamber are separated by a diaphragm, etc., and then assembled.The diaphragm, etc. is destroyed by a signal given from the outside at the time of startup, and the electrolyte in the electrolyte chamber is Yli
It is activated by injecting a liquid into the electrode chamber, and it is essential that it can be stored for a long period of time in a usable state, that is, with the electrolyte chamber filled with electrolyte. However, some electrolytes for injection batteries use aqueous caustic potassium solution, sulfuric acid, etc. In this case, there was a problem that due to its strong permeability, it leaked from the structural attachment part of the diaphragm.

十分な効果が得られないという欠点があった。In order to solve the above problems, in conventional injection type batteries, a diaphragm mounting flange a is provided at the end of the electrolyte chamber 1 where the electrolyte 2 is filled, as shown in FIG. 7
It has been practiced to braze the diaphragm 3 to the lunge B with a brazing filler metal 4. For example, when the injection type battery is a silver-zinc oxide battery, the electrolyte chamber 1 is made of stainless steel and the diaphragm 3 is made of steel plate, so silver solder is most suitable as the filler metal 4. contains 10 to 30% each of copper, zinc, and cadmium eluted into the electrolyte, a caustic potassium aqueous solution.
The corrosion resistance against the electrolyte was not perfect. In other words, if there is a sufficient amount of electrolyte to cause the substance to elute and cause leakage, and if there is dissolved oxygen in the electrolyte, countless minute holes will form in the silver solder during long-term storage. It turned out that this led to leakage. In this case, brazing with silver solder can lengthen the leakage path by making the part long enough to lengthen the leakage path, but it is difficult to braze evenly and it is difficult to do so. , brazing may cause pin holes in the part,
The drawback was that sufficient effects could not be obtained.
