Manganese zinc sodium oxide material, preparation method thereof and application of manganese zinc sodium oxide material in sodium ion battery

The invention relates to the technical field of sodium-ion battery electrode materials, in particular to a sodium manganese zinc oxide material, a preparation method thereof and application of the sodium manganese zinc oxide material in a sodium-ion battery. The manganese zinc sodium oxide material is prepared by sintering manganese sesquioxide, sodium carbonate and a sodium zincate solution as raw materials at high temperature; the sodium zincate solution is added in the process of preparing the sodium manganese oxide to prepare the sodium manganese zinc oxide material, and the finally obtained sodium manganese zinc oxide material contains part of zinc element, so that part of dislocation is generated in the sodium manganese oxide, the disproportionation reaction of the manganese element is limited in the charge-discharge process, the stability of the structure is effectively improved, and the service life of the material is prolonged. And the battery life is prolonged. 本发明涉及钠离子电池电极材料技术领域，具体涉及氧化锰锌钠材料及其制备方法和在
