Recent progress and advances of high-entropy polyanionic cathodes in lithium-ion and sodium-ion batteries

high-entropy doping, such as enhanced ion/electron transport and phase stability. Finally, the characteristics of high-entropy polyanionic cathodes for lithium-ion and sodium-ion batteries were summarized. In addition, we describe the challenges encountered in this research area as well as potential future directions for the implementation of high-entropy strategies in the field of polyanionic cathode materials.
