PURPOSE:To prevent an increase of the inner resistance owing to the corrosion of a positive electrode container by using a ferrite type stainless steel which consists of a specific weight ratio of chromium, molybdenum, and ion for the positive electrode container. CONSTITUTION:In a positive electrode container 1, a positive electrode 3 is installed through a collector 2 which consists of a stainless steel net. On the positive electrode 3, a separator 4 and a negative electrode 5 which consists of metal lithium are loaded. And at the opening of the positive electrode container 1, a negative electrode container 7 is arranged, and the positive electrode 3, the separator 4, and the negative electrode 5 are enclosed in the positive electrode container 1 and the negative electrode container 7 by a calking process of the negative electrode container 7. As the positive electrode container 1, a ferrite type stainless steel which consists of chromium 24 to 40wt.%, molybdenum 0.5 to 3wt.%, and iron of the remaining wt.-% is used. Consequently, an increase of the inner resistance owing to the corrosion of the positive electrode container can be prevented. |
