Abstract
The invention discloses a disassembling processing method of waste sodium-sulfur cells. The method comprises discharging the sodium-sulfur cells, cooling an electric furnace from an operating temperature to a room temperature, taking out the cell bodies, successively disassembling anode tabs and cathode covers from the cell bodies by using cutting tools, cleaning a cathode core tube with alcohol, then pulling out the cathode core tube from an electrolyte ceramic tube, successively disassembling cell bottom covers and lower sealing parts from the cell bodies by using the cutting tools, splitting a housing, immersing, cleaning sodium polysulfide in carbon felts between the housing and the electrolyte ceramic, and finally separating the electrolyte ceramic tube from the carbon felts and the housing. The disassembling processing method of waste sodium-sulfur cells is simple to operate and environment-friendly, totally prevents generation of fire hazards and other dangerous situations caused by reactions of moisture in the environment, oxygen and a high-temperature environment with metallic sodium, sodium polysulfide, sulfur and the like in the waste sodium-sulfur cells, and has an important practical value for processing the waste sodium-sulfur cells.
Description
Technical field
The present invention relates to a kind of disassembling method of sodium-sulphur battery, relate in particular to a kind of disassembly processing method of waste and old sodium-sulphur battery.
