“…Furthermore, the excellent electrochemical performance is determined and demonstrated by the improved kinetics, including a large capacitive contribution (79.6% at 0.5 mV s −1 ) and fast ion migration. Liu et al 119 showed higher electrochemical performance using chlorine-doped graphenecoated NVP composites. Among the composites, appropriately chlorinated Na 3 V 2 (PO 4 ) 2.9 Cl 0.3 @C (NVP@C/Cl-30) exhibited the best performance.…”

The polyanion sodium vanadium phosphate Na3V2(PO4)3 (NVP) belongs to the sodium superionic conductors (NASICON) material. Its NASICON structural backbone forms a stable sodium accommodation site, and the open three-dimensional ion transport channel is conducive to the rapid intercalation/deintercalation of Na ions. As a cathode material for batteries, Na3V2(PO4)3 has an extremely high specific capacity, voltage plateau, and cycle stability, meeting the requirements of low cost and high safety. It is a large-scale energy storage material with ideal potential and has received extensive attention. However, the low electronic conductivity of Na3V2(PO4)3 material hinders its further application. Based on the current demand for large-scale application of sodium-ion batteries, this paper re-examines the effect of existing research progress on promoting practical applications and the problems that need to be solved in the future from the perspective of raw material cost system and process complexity. The paper first introduces the structural characteristics of Na3V2(PO4)3 material and the mechanism of sodium-ion intercalation/deintercalation. Then it introduces the synthesis methods, such as the sol–gel method, hydrothermal method, and solid-phase reaction method. In addition, it summarizes the modification studies of Na3V2(PO4)3, including carbon coating, ion doping and, morphology control, design of composite materials and structures based on Na3V2(PO4)3. Finally, it discusses the possible future development of Na3V2(PO4)3.

Sodium–ion batteries (SIBs) are essential for large–scale energy storage attributed to the high abundance of sodium. Polyanion Na3V2(PO4)3 (NVP) is a dominant cathode candidate for SIBs because of its high-voltage and sodium superionic conductor (NASICON) framework. However, the electrochemical performance of NVP is hindered by the inherently poor electronic conductivity, especially for extreme fast charging and long-duration cycling. Herein, we develop a facile one-step in-situ polycondensation method to synthesize the three-dimensional (3D) Na3V2(PO4)3/holey-carbon frameworks (NVP@C) by using melamine as carbon source. In this architecture, NVP crystals intergrown with the 3D holey-carbon frameworks provide rapid transport pathways for ion/electron transmission to increase the ultrahigh rate ability and cycle capability. Consequently, the NVP@C cathode possesses a high reversible capacity of 113.9 mAh g–1 at 100 mA g–1 and delivers an outstanding high–rate capability of 75.3 mAh g–1 at 6000 mA g−1. Moreover, it shows that the NVP@C cathode is able to display a volumetric energy density of 54 Wh L−1 at 6000 mA g−1 (31 Wh L−1 for NVP bulk), as well as excellent cycling performance of 65.4 mAh g−1 after 1000 cycles at 2000 mA g−1. Furthermore, the NVP@C exhibits remarkable reversible capabilities of 81.9 mAh g−1 at a current density of 100 mA g−1 and 60.2 mAh g−1 at 1000 mA g−1 even at a low temperature of −15 °C. The structure of porous carbon frameworks combined with single crystal materials by in-situ polycondensation offers general guidelines for the design of sodium, lithium and potassium energy storage materials.
