Abstract

Common polyanionic materials, such as NaTi₂(PO₄)₃, Na₃V₂(PO₄)₃ and Na₂VTi(PO₄)₃, were prepared by an ultrafast high-temperature sintering technology in about 30 s. In particular, as a sodium-ion anode material, NaTi₂(PO₄)₃ exhibits remarkable electrochemical performance, maintaining a capacity of 100.9 mA h g⁻¹ after 8000 cycles at 1 A g⁻¹ without noticeable capacity decay.
