【摘要】：磷酸钒钠储量丰富,成本低,对环境友好,具有钠快离子导体十分稳定的结构,离子导电性好,比能量高,热稳定性好,安全性高,被认为是最具潜力的钠离子电池正极材料,但自身电子电导率低,在实际应用中受到限制。从制备方法和改性方面介绍了近年来Na_3V_2(PO_4)_3的研究进展,并对其前景进行了展望。
[Abstract]:The sodium vanadium phosphate is rich in reserves, low in cost, environmentally friendly, with a very stable structure of sodium fast ionic conductors, good ionic conductivity, high specific energy, good thermal stability, high safety, and is considered to be the most promising cathode material for sodium ion batteries. However, its electronic conductivity is low, which is limited in practical application. The research progress of Na_3V_2(PO_4)_3 in recent years is introduced from the aspects of preparation method and modification, and its prospect is prospected.
