Summary:[Display omitted] •The O3-NaTi7/10Ni3/20Mg3/20O2 anode material was prepared via solid state reaction.•To the best of our knowledge this material has been prepared for the first time.•Ni and Mg swap in Ti sites improved reversibility of Na+ during cycling.•The as-prepared material delivers reversible capacity 113.08 mAh g−1. Here, we prepared O3-NaTi7/10Ni3/20Mg3/20O2 anode material via conventional solid-state reaction for sodium-ion batteries. The prepared anode material revealed the rhombohedral structure with the space group of R-3m. The existence of Na-O bond was identified using Fourier-Transform Infrared spectra. The hexagonal shaped morphology of the material was observed. The layered O3-NaTi7/10Ni3/20Mg3/20O2 anode material delivered a reversible capacity of 113.08 mAh g−1 in the voltage range of 0.2–2.5 V at 0.1 C rate.
