Abstract
In this work, NaFeTi3O8 with three-dimensional porous net-like sheetmorphology is firstly prepared by a simple and effective solutioncombustion method. Encouragingly, when being assessed as an anodeelectrode for sodium ion batteries, the NaFeTi3O8 net-like sheetcomposite exhibits superior electrochemical properties. We also studythe effect of the combustion fuel glycine. The results indicate that theNaFeTi3O8 composite tends to be porous with glycine as thecombustion fuel, which displays more excellent long cyclic stability(discharge capacity of 91 mA h g−1 after 1000 cycles at the currentdensity of 0.5 A g−1) and superior rate performance (84.4 mA h g−1even at 1.6 A g−1) than that of NaFeTi3O8 without glycine as thecombustion agent. The enhanced electrochemical properties could beascribed to the unique porous morphology, which achieves betterelectrolyte infiltration and faster ion diffusion.
