Na4Fe3(PO4)2P2O7 (NFPP) is recognized as a prospective electrode for sodium-ion batteries (SIBs) because of its structure stability, economic viability and environmental friendliness. Nevertheless, commercialization constrained by low operating voltage limited theoretical capacity, which result in power density significantly inferior to that LiFePO4. To address these limitations, this work, we first designed synthesized series Mn-doped NFPP enhance voltage, inspired the successful design LiFe1-xMnxPO4 cathodes. This approach was implemented material. Subsequently, optimized Na4Fe1.2Mn1.8(PO4)2P2O7 (1.8Mn-NFMPP) sample selected further Ti-doped modification cycle durability rate performance. The final Mn/Ti co-doped Na4Fe1.2Mn1.7Ti0.1(PO4)2P2O7 (0.1Ti-NFMTPP) material exhibited high ~3.6 V (vs. Na+/Na) half cell, with an outstanding reversible capacity 122.9 mAh g-1 at 0.1 C remained 90.6% retention after 100 cycles 0.5 C. When assembled into coin-type full cell employing commercial hard carbon anode, cathode initial 101.7 g-1, retaining 86.9% over 50 These results illustrated optimal co-doping effective methodology boost electrochemical behavior materials, achieving mitigation Jahn-Teller effect on Mn3+ Mn dissolution problem, thereby improving structural stability cycling
