Problems solved by technology
[0006] The disadvantage of this technical solution is that the life detection equipment of the electrolyte ceramic tube of the sodium-sulfur battery is far from the sodium-sulfur battery in structure and manufacturing process, and assembly is difficult, and the life detection equipment of the electrolyte ceramic tube of the sodium-sulfur battery must be used under an inert atmosphere , and the life detection equipment of the electrolyte ceramic tube of the sodium-sulfur battery is a one-way sodium guide, which is quite different from the actual operation process of the sodium-sulfur battery, and it is impossible to test the accurate life of the electrolyte ceramic tube, that is, the number of cycles

The invention relates to the filed of energy storage, and discloses a service life detection device for a sodium-sulfur battery and an electrolyte ceramic pipe. The service life detection device comprises a sodium sodium battery and an external charging / discharging device. The sodium sodium battery comprises a battery shell and the electrolyte ceramic pipe. The battery shell and the electrolyte ceramic pipe are sealed through a ceramic insulating ring and an anode sealing ring to form the anode of the sodium sodium battery. The electrolyte ceramic pipe and the ceramic insulating ring are sealed through a cathode sealing cover and a cathode sealing ring to form the cathode of the sodium sodium battery. A current switching device is arranged between the sodium sodium battery and the external charging / discharging device. The current switching device switches the direction of the charging current generated when the external charging / discharging device charges the sodium sodium battery so that the charging current can be switched between two states that the charging current either flows to the cathode of the sodium sodium battery from the anode of the sodium sodium battery or flows to the anode of the sodium sodium battery from the cathode of the sodium sodium battery.
