するためである。Problems to be Solved by the Invention However, in a battery having such a conventional configuration, the selection of the material for forming the battery case 1, which is the part electrically connected to the positive electrode and in contact with the electrolyte, is a major problem. Become. For example, if nickel-plated steel, nickel, or the like is used as the material for the battery case 1 as in the conventional example, capacity deterioration occurs during the storage period. This is because these metals such as nickel are dissolved in the electrolytic solution, and due to the difference in ionization tendency, metals such as nickel are deposited on the lithium surface and dissolve the lithium. In order to solve these problems, it was proposed in JP-A-51-89135 to use steel that does not contain nickel and contains chromium of 20% or more by weight for battery cases. When this material was used in batteries, satisfactory results were obtained in terms of corrosion resistance and processability, but
Capacity deterioration was confirmed when stored at higher temperatures for a long period of time. This is because, under conditions of high temperature and long periods of time, the case material dissolves into the electrolyte, similar to nickel-plated steel.
また、アルミニウムを電池ケースに用いた場合、保存特

池ケースの強度を低下させない。Effect: According to the above configuration, the aluminum layer on the inner surface of the battery case comes into direct contact with the organic electrolyte and the positive electrode. In this case, since the surface of the aluminum layer is covered with a highly corrosion-resistant oxide layer formed by reacting with oxygen, it does not dissolve into the organic electrolyte unlike conventional battery cases. Furthermore, since the aluminum layer is provided on the battery case, the strength of the battery case is not reduced.

Measured under the following conditions. As a comparative example, conventional battery cells R and F with the same configuration except that no aluminum layer was provided and the battery case was made of nickel-plated steel, stainless steel containing 20% chromium, and aluminum were used.
The capacity was also measured under the same conditions as described above. These results are shown in the table below.

Then, in order to provide the aluminum layer 7 & on the battery case 7 made of stainless steel,

表わした。Next, a battery having a diameter of 20H1 and a height of 2ff was fabricated using a battery case 7 made of stainless steel with a thickness of 0.3 mm and an aluminum layer 71L each having a thickness of 2 to 18 μm. Figure 2 shows that for each of these batteries, 8
These are the results of measuring capacity deterioration after being stored for three months in an atmosphere of 0'C. In addition, as a measurement condition, discharge resistance so
The test was carried out in a kΩ, 20'C atmosphere, and the ratio of the decrease in capacity after storage to the capacity of the battery before storage was expressed as the capacity deterioration rate.

ることができる。As is clear from FIG. 2, the aluminum layer 71L with a thickness of 10 μm or less deteriorates rapidly;
For those with a diameter of 1 μm or more, the ratio is generally 1. This means that the thickness of the aluminum layer 7a is 10 μm.
This is because if the temperature is below, the electrolytic solution comes into contact with the stainless steel due to the non-uniform structure of the aluminum m7a, and the stainless steel dissolves in the electrolytic solution. Therefore, by setting the thickness of the aluminum layer 71L to 1 μm or more, it is possible to substantially prevent the battery from deteriorating its capacity after being stored in a high-temperature atmosphere.
