PURPOSE:To prevent breakage of battery caused in battery assembly or high temperature operation by pressing the inner circumference of circular cathode conductive material with a circular metal member, and filling molten-sulfur resistant material powder between the inner bottom of a container and the lower part of a solid electrolyte tube. CONSTITUTION:The inner circumference of a circular cathode conductive material 11 is pressed with a circular metal member 13. Molten-sulfur resistant material powder or particle or their mixture 14 is filled between the inner bottom 5' of the inside of the circular metal member 13 and the lower end 1' of a solid electrolyte tube 1. Thereby, shock in battery assembly is absorbed by the powder, particles, or the mixture 14. In high temperature operation, the cathode conductive material 11 expands in a central direction and the metal member 13 is pressed in a central direction and the solid electrolyte tube 1 is supported by the mixture 14. Thereby, breakage of the battery caused in battery assembly or high temperature operation can be prevented. |
