Cover Story: The synergistic effects of co-doping titanium (Ti) and vanadium (V) on P2-type Na_0.67Fe_0.5Mn_0.5O₂ cathode is investigated in this study to address the structural instability arising from the destructive Jahn-Teller (JT) distortion effect of Mn³⁺/ Mn⁴⁺ during cycling. The Ti and V co-doping improved the crystallinity of the cathode structure, and it also enhanced the structural stability and mitigated the phase transition from P2 to OP4 at higher voltages. The investigation involved a comprehensive analysis of structural properties and an evaluation of electrochemical performance. The co-doping enhanced the energy density, ion transport, stability, and capacity retention. The research findings revealed an avenue toward the enhanced performance and longevity in sodium-ion batteries for advanced energy storage applications. View this paper
