description The invention relates to a method for preparing a sodion battery positive electrode material NaCrxFe1-xO2 (0 < x < 1) from carbon ferrochrome to solve the problem of non-uniform mixing of a chromium-containing raw material and an iron-containing raw material by adopting a routine method. The preparation method concretely comprises the following steps: performing crushing, screening and impurity removal on the cheap and easily available carbon ferrochrome used as a raw material, fully mixing and uniformly grinding the obtained carbon ferrochrome and a sodium source, performing a high temperature sintering reaction, and cooling the obtained reaction product to obtain the final product. Cr and Fe elements are uniformly distributed in the carbon ferrochrome, so the two elements are uniform distributed in the positive electrode material sodium chromium ferrite prepared from the carbon ferrochrome, and the final product is a pure phase substance, and contains no other iron-containing or chromium-containing impurity
