は二次電池に関するものである。The present invention relates to a negative electrode whose active material is a light metal such as lithium and sodium, and a positive electrode whose active material is a metal oxide, sulfide or halide. The present invention relates to a primary or secondary battery provided with a water electrolytic solution.

ニツケル量に依存すると考えられニツケル量が大なるほ
ど顕著であつた。(B) Conventional technology In this type of battery, a so-called austenitic stainless steel having a nickel content of about 3 to 20% by weight is used as a material for a positive electrode constituent member that directly or indirectly contacts a positive electrode active material, for example, a positive electrode can or a positive electrode current collector. Is generally used, the positive electrode can and the positive electrode current collector, which are electrically connected to the positive electrode during storage of the battery, have their constituent metals dissolved in the electrolytic solution and deposited on the negative electrode to increase the internal resistance. In extreme cases, a perforation phenomenon may occur. This cause is considered to depend on the amount of nickel contained in the stainless steel, and was more remarkable as the amount of nickel increased.

れた。Therefore, as disclosed in, for example, Japanese Patent Publication No. 55-15067, it has been proposed to use ferrite stainless steel containing almost no nickel as a positive electrode constituent member and having little cracking susceptibility under stress. Even when stored at high temperature for a long time, the phenomenon of dissolution of the positive electrode constituent member was observed.

微少電流とは高々数μＡであるが、このような微少電流
放電下において長期間安定した放電特性を得るためには
電池自身の高信頼性が要求される。By the way, this type of battery can withstand long-term use because it has a smaller self-discharge than conventional silver batteries and alkaline batteries. Therefore, the stability of discharge characteristics over a long period of time has been required. The minute current described here is at most several μA, but in order to obtain stable discharge characteristics for a long period of time under such minute current discharge, high reliability of the battery itself is required.

れている。Further, in recent years, the secondary system of the specific water electrolyte battery has been actively developed, and when the positive electrode constituent members are dissolved and the positive electrode constituent metal ions are deposited on the negative electrode during charging, the charge and discharge efficiency of the negative electrode is reduced and the cycle characteristics are reduced. Therefore, there is a demand for a positive electrode constituent member that is difficult to dissolve, in other words, has excellent corrosion resistance.

を指す。Here, the ferritic stainless steel is an alloy mainly composed of Fe-Cr, and in terms of composition, it contains Cr 11 to 27% and has a carbon content of 0.2% or less. In terms of texture, it means that it falls within the range of α (body-centered cubic lattice) or α + γ (face-centered cubic lattice), and has almost no quench-hardenability.
