Abstract:

© 2018 Sodium super-ionic conductor (NASICON) structured Na3V2(PO4)3 (NVP), a promising cathode material for sodium-ion batteries (SIBs), benefits by its unique three-dimensional (3D) channel structure. However, the inherent characteristics of NVP (such as low electrical conductivity) usually lead to inferior rate and long-cycling performance, which miss the requirements of practical application in electrical energy storage systems (ESSs). Herein, we propose the synthesis of porous high-crystalline Na3V2(PO4)3/C nanoplates (NVP/C-P) via hydrothermal method and post-calcination. The porous nanoplate structure provides increased specific surface area and shortened diffusion pathway for ion/electron transport. Consequently, NVP/C-P cathodes exhibit a high specific capacity (117 mAh g−1, 0.2 C), exceptional rate performance (76.5 mAh g−1, 100 C) and long cyclic stability (10,000 cycles).
