PURPOSE:To increase space efficiency and to prevent the generation of a gap in a bonding part of a cathode conductive material by forming a cathode container and a solid electrolyte tube in a similar polygonal cylindrical shape, forming a space accommodating the cathode conductive material between them, and installing a bonding part in a vertex of the polygon. CONSTITUTION:A cathode container 2a is formed in a polygonal cylindrical shape and a solid electrolyte tube 4a is also formed in a similar polygonal cylindrical shape, and a space for accommodating a cathode conductive material 8a is formed between them. The cathode conductive material 8a is expansible in a thickness direction, and a bonding part is installed in a vertex of the polygon. Thereby, the volume of the cathode conductive material 8a accommodated in the space is increased, and much more sulfur of cathode active material and sodium of anode active material can be accommodated. Two L-shaped bonding parts of cathode conductive material 8a are closely sticked by the restoration of the cathode material 8a. |
