Summary: Sodium-ion batteries (SIBs) have developed rapidly due to the abundance, distribution, and low cost of sodium. Sodium superion conductor (NASICON) based electrode materials are promising for sodium storage, but their low electronic conductivity limits their electrochemical performance. Strategies such as coating with carbon, reducing size, combining with other carbon materials, and doping elements have been studied to enhance the conductivity of NASICON-based cathode materials.
