Cation/Anion-Dual regulation in NaMnTi(PO) cathode achieves the enhanced electrochemical properties of Sodium-Ion batteries.

NaMnTi(PO) (NMTP) emerges as a promising cathode material with high-performance for sodium-ion batteries (SIBs). Nevertheless, its development has been limited by several challenges, including poor electronic conductivity, the Mn Jahn-Teller effect, and the presence of a Na/Mn cation mixture. To address these issues, we have developed a cation/anion-dual regulation strategy to activate the redox reactions involving manganese, thereby significantly enhancing the performance of NMTP.
