Sodium–sulfur (Na–S) batteries are considered as a promising successor to the next-generation of high-capacity, low-cost and environmentally friendly sulfur-based battery systems. However, Na–S batteries still suffer from the "shuttle effect" and sluggish ion transport kinetics due to the dissolution of sodium polysulfides and poor conductivity of sulfur. MXenes,
The earliest sodium-sulfur battery was constructed in the laboratory of Ford Motor Company, and Kummer and Weber confirmed its feasibility . The battery uses sodium and sulfur as the active materials for the cathodes and anodes, and β-Al 2 O 3 ceramics are used as both the electrolyte and the separator.
The sodium-sulfur battery realizes the conversion between chemical energy and electrical energy through the electrochemical reaction between metallic sodium and elemental sulfur . When discharging, sodium metal produces Na + and electrons. Na + moves with the electrolyte through the separator to the sulfur cathode.
In summary, in order to obtain a room temperature sodium–sulfur battery with stable cycle performance and long life, the most important task of the separator is to guide the migration of Na + and inhibit the shuttle of polysulfides. Sodium polysulfide dissolved in the electrolyte must pass through the separator to reach the anode.
