Titanium based layered 03-NaTi_(7/10)Ni_(3/20)Mg_(3/20)O_2 anode material for sodium ion batteries

摘要

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. (C) 2020 Elsevier B.V. All rights reserved.
