Abstract Over the last decade, Na‐ion batteries have been extensively studied as low‐cost alternatives to Li‐ion for large‐scale grid storage applications; however, development of high‐energy positive electrodes remains a major challenge. Materials with polyanionic framework, such Na superionic conductor (NASICON)‐structured cathodes formula x M 2 (PO 4 ) 3 , attracted considerable attention because their stable 3D crystal structure and high operating potential. Herein, novel NASICON‐type...
