3D graphene decorated NaTi 2 (PO 4 ) 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.
