Status and Challenges of Cathode Materials for Room‐Temperature Sodium–Sulfur Batteries

Room‐temperature sodium–sulfur (RT Na–S) batteries have become the most potential large‐scale energy storage systems due to the high theoretical energy density and low cost. However, the severe shuttle effect and the sluggish redox kinetics arising from the sulfur cathode cause enormous challenges f...
