It has not been generally considered to put this coating into practical use because the resulting coating becomes porous and is therefore unsuitable for maintaining long-term durability. However, the inventor of the present invention has discovered that by plasma spraying the inner surface of the anode container, it is possible to form a coating that has a specific thickness, porosity, and surface roughness that can maintain long-term durability for practical use. They discovered this and completed the present invention.

It is made of metal such as L alloy, Fe-based alloy, Ni-based alloy, or cladding material of these materials. In particular, Al and Al alloy, which are excellent in lightness and workability, are preferable, and the thickness is 1.
It is normal that the thickness is approximately 5 mm, but it is 1.5 to 2.2 mm in consideration of deformation prevention and economic efficiency when forming a corrosion-resistant coating 2 as described later on the inner surface by plasma spraying.

In particular, stellite alloy is preferable for improving corrosion resistance, and if the thickness is less than 100 μm, sufficient corrosion resistance cannot be obtained for a long period of time.
Moreover, since it is economically disadvantageous to make the thickness thicker than 200 μm, the thickness is preferably 100 to 200 μm. Note that 3 is sulfur which is a positive electrode active material, and 4 is metallic sodium which is a negative electrode active material isolated by a solid electrolyte tube 5.

There is a need to. On the other hand, the surface roughness of the inner surface of the container body 1 to which plasma spraying is applied is 2 to 15 μm in order to improve the adhesive strength of the corrosion-resistant coating 2 and to obtain a corrosion-resistant coating with a uniform thickness without any thin areas. It is preferable to have a smooth surface within the range of 5 to 8 μm, preferably 5 to 8 μm. In addition, the corrosion-resistant coating 2, which has an extremely smooth coating surface without such irregularities, has no thin film portion, so it exhibits excellent durability over a long period of time without being preferentially corroded by sulfur or the like.

After a bottomed cylindrical container body 1 with an inner surface finished with a smooth surface roughness within a predetermined range is manufactured by a conventional method, it is preheated to about 200°C and then held by a gripper 6 as shown in FIG. Hold it vertically and rotate the gripper 6 to apply it to the container body 1 at 100 to 700 rpm.
Gives rotation. Then, a nozzle of a plasma spray gun 7 with an output of 7 to 50 KW is inserted into the rotating container body 1, and the plasma spray gun 7 is moved at a traverse speed of 2 to 50 KW.
While moving up and down in the axial direction of the container body 1 at a rate of 15 mm/sec, a thermal spraying material 8 such as stellite is injected from the tip of the nozzle and uniformly plasma-sprayed onto the inner surface of the container body 1 at a temperature of about 200°C. A corrosion-resistant coating 2 is formed on the inner surface of the container body 1 by plasma spraying. In this case, there is a gap between the nozzle of the plasma spray gun 7 and the inner surface of the container body 1.
The spacing is adjusted to be 5 to 30 mm, preferably 15 to 20 mm, so that the corrosion-resistant coating 2 formed by plasma spraying has a uniform thickness.
