description The invention discloses a polyanionic sodium ion battery positive electrode material and a preparation method thereof, the polyanionic sodium ion battery positive electrode material has a general formula of Na4MxP4O12 + x, the value range of x is greater than or equal to 2.0 and less than or equal to 4.0, and M is one or two of Fe, Co, Ni, Cu, Zn and Mn; by controlling the change of the x value, the polyanion type sodium ion battery positive electrode material is in a single phase or two phases. The polyanionic sodium ion battery positive electrode material has the characteristics of strong theoretical guidance, low production cost and high product purity. 本发明公开了一种聚阴离子型钠离子电池正极材料及其制备方法，聚阴离子型钠离子电池正极材料通式为Na4MxP4O12+x，其中，x的取值范围为2.0≤x≤4.0,M为Fe、Co、Ni、Cu、Zn、Mn中的一种或两种；通过控制x值的变化，聚阴离子型钠离子电池正极材料为单相或两相。本发明的聚阴离子型钠离子电池正极材料具有理论指导性强、生产成本低和产品纯度高的特点。
