A kind of sodium-sulphur battery recovery method of the present invention, comprises the following steps:
Discharge step: carry out complete discharge process before sodium-sulphur battery is retired, so can make the internal highly active SODIUM METAL of sodium-sulphur battery and sulfur be largely converted into SA sodium polysulphide, be stored in carbon felt 2, to improve the safety of sodium-sulphur battery processing procedure.If sodium-sulphur battery exits Status unknown during military service, first sodium-sulphur battery can be carried out complete discharge process, at utmost to reduce the amount of the internal SODIUM METAL of sodium-sulphur battery and sulfur.
Metal material recycling step: cut the positive pole ear 51 on the shell 1 of sodium-sulphur battery, and top seals the negative lug 52 on lid 5.
Along the circumference of the bottom surface of ceramic insulation ring 4, namely on the top of shell 1, the circumference along shell 1 cuts the first cutting seam 11.In shell 1 bottom, the circumference along shell 1 cuts the second cutting seam 12.On shell 1, cut the 3rd cutting seam 13 connecting the first cutting seam 11 and the second cutting seam 12 along vertical direction simultaneously.At the 3rd cutting seam 13 places, along the first cutting seam 11 and the second cutting seam 12, shell 1 and carbon felt 2 are peeled off.
