3D Graphene Decorated NaTi₂(PO₄)₃ Microspheres as a Superior High‐Rate and Ultracycle‐Stable Anode Material for Sodium Ion Batteries

Abstract

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.
