Sodium ion battery cathode material, and a preparation method and application therefor

Abstract

The present disclosure relates to a sodium ion battery cathode material, and a preparation method and application therefor. The method for preparing a sodium ion battery cathode material of the present disclosure includes the following steps: (A) grinding a mixture of sodium borohydride and ferric manganese hydroxide to obtain first slurry, and performing spray drying and calcination on the first slurry to obtain a first calcinated material; and (B) grinding a mixture of the first calcinated material, a carbon source, a vanadium source, sodium bicarbonate, and water to obtain second slurry, and performing spray drying, calcination, crushing, sieving, and iron removal on the second slurry to obtain a sodium ion battery cathode material. The method is simple in step and low in cost, and the prepared sodium ion battery cathode material has the characteristics of being good in conductivity, high in capacity, high in energy density, etc.
