However, under high-voltage conditions exceeding 4.2 V, these materials are prone to undergo P2-O2 phase transformation and irreversible loss of lattice oxygen, leading to rapid capacity decay. To address these challenges, this work proposes a titanium-doping modification strategy, synthesizing a series of Ti-doped P2-type Na_0.7Fe_0.14Cu_0.09Mn_0.77-xTi_xO₂ (x = 0, 0.02, 0.05, 0.08) cathode materials, exploring the effect of Ti doping on the crystal structure and assessing the electrochemical performance of the materials. Results demonstrate that the incorporation of Ti into the transition metal layer stabilizes the layer structure, expends the Na layer spacing, and enhances Na⁺ diffusion kinetics. The Na_0.7Fe_0.14Cu_0.09Mn_0.72Ti_0.05O₂ (FCMT-5) electrode delivers a high initial discharge capacity of 164.36 mAh g⁻¹ in 1.5–4.5 V, retains 78.89% after 100 cycles at 1 C, while the pristine one only yields 58.62% capacity retention. Besides, a high initial specific discharge capacity of 107.31 mAh g is retained at a high rate of 5C. Mechanistic analysis indicates that Ti doping not only suppresses the P2-O2 phase transition and lattice oxygen loss at high voltages but also reduces Mn³⁺ content through charge compensation, alleviating Jahn–Teller distortion.

The deposit composition depends on C.E., with Al C.E. yielding a maximum of 4.06 atom% Mg and Pt C.E. offering up to 13.69 atom% Mg. Contrarily, deposit phases are functions of compositions irrespective of the C.E.

When employing Al C.E., the deposit’s less noble metal i.e. Mg content increases with deposition potential and decreases with temperature, suggesting the nature of this electrodeposition as ‘regular’. However, the nature of deposition with Pt C.E. is ‘equilibrium’.

Correlating their morphological behaviour with electrochemical performance as MXene may be a suitable candidate for future energy storage materials. Among the yielded samples, 30% HF etched sample dictates the highest electrochemical performance at low scan rates (201 F/g at 2 mV/s), attributed to efficient ion diffusion kinetics and stable layered structure for energy storage. At higher scan rate, the constraint in ion diffusion and electronic transport is observed under rapid charge discharge process.
