Recent Progress of Na3MnTi(PO4)3 Cathode for Sodium-Ion Batteries: Mechanism, Synthesis, and Optimization Strategy

Sodium-ion batteries (SIBs) have exhibited significant commercial potential, benefiting from the abundance and global distribution of sodium resources. Among the diverse cathode materials under exploration for SIBs, Na₃MnTi(PO₄)₃ (NMTP) stands out as a highly promising candidate for practical applications, which combines the structural stability and high-voltage characteristics inherent to NASICON-type materials. In recent years, substantial advancements have been achieved in the research of NMTP. However, a comprehensive and up-to-date specialized review dedicated to its research progress and prospects remains lacking. This review, therefore, aims to systematically discuss the development and outlook of NMTP cathode material. Initially, the manuscript delves into the crystal structure and sodium-storage mechanism of NMTP. Subsequently, the synthesis methods, electrochemical properties, and optimization strategies are explored. Finally, the review outlines current challenges and suggests potential future research directions for NMTP.
