文摘

3D graphene decorated NaTi₂(PO₄)₃ (NTP@rGO) is successfully synthesized through a facile spray-drying method. This NTP@rGO material can deliver high reversible capacity (130 mAh g⁻¹ at 0.1 C), superior high-rate rate capability (38 mAh g⁻¹ at 200 C) and long cycling stability (77% capacity retention after 1000 cycles), suggesting its applicability as a high rate and cycle-stable anode for the development of high-power and long cycle life sodium ion batteries for energy storage applications.
