Key Points

  • Investigate the effects of high-entropy doping on the stability and energy density of sodium-ion battery cathodes.
  • Evaluated the performance of the P2-type Na2/3Ni1/3Mn2/3O2 cathode material.
  • Conducted synthesis and characterization of layered oxide structures.
  • Analyzed the electrochemical performance and stability over cycles.
  • The high-entropy doped cathode exhibited enhanced energy density.
  • Improvements in stability were observed over extended cycling.
  • Performance metrics exceed conventional doping methods.

Abstract

Layered oxides are considered promising cathode materials for sodium-ion batteries due to their high theoretical capacity and ease of synthesis. Among these, the P2-type Na2/3Ni1/3Mn2/3O2 (NM) cathode has attracted significant...
