Abstract

PURPOSE:To retard the corrosion of a positive can and increase the storage life at high temperature by using ferritic stainless steel containing a specified amount of silicon as a material of a positive can of nonaqueous electrolyte battery. CONSTITUTION:A positive can 5 is formed with ferritic stainless steel containing 1.2-5.0wt% silicon. A positive electrode 4 using metal oxide or halide as active material is fixed inside the positive can 5 and combined with a separator 7, a negative electrode 1 using light metal such as lithium and sodium as active material, and nonaqueous electrolyte to forma nonaqueous electrolyte battery. Since silicon reduces intergranular corrosion sensitivity in the electrolyte, the corrosion of the material constituting the positive can 5 is prevented. Therefore, even when a battery is stored at high temperature for a long time, the corrosion of the positive can 5 is prevented, and the storage life is increased.

(b) Conventional technology The can material for this type of power supply has a nickel content of approximately 3 to 2.
0% by weight so-called austenitic stainless steel is generally used, but during battery storage, the positive electrode can, which is electrically connected to the positive electrode, has its constituent members dissolved in the electrolyte and deposited on the negative electrode, increasing the internal resistance. and, in extreme cases, may cause a perforation phenomenon. The cause of this is thought to depend on the amount of nickel contained in the stainless steel, and was more pronounced as the amount of nickel increased.

Therefore, for example, as disclosed in Japanese Patent Publication No. 55-15067, it has been proposed to use ferritic stainless steel, which contains almost no nickel and is less susceptible to cracking under stress, as a component of the positive electrode can. However, when stored at high temperatures for long periods of time, melting of the constituent parts was observed.

Now, compared to conventional silver and alkaline batteries, this type of power supply has a smaller self-discharge and can withstand long-term use.As a result, recently, it has become possible to use a small current due to the regeneration of electronics in the equipment used. The stability of discharge characteristics over a long period of time is now required. The microcurrent referred to above is a few μ^ at most, but in order to obtain stable discharge characteristics for a long period of time under such microcurrent discharge, the battery itself is required to have high reliability.
