The invention discloses a ferromanganese binary hydroxide precursor, a preparation method and application thereof. The method comprises the following steps: 1) preparing a manganese source solution, a complexed iron source solution, and a bottom liquid respectively; the bottom liquid comprises a bottom liquid of a reducing agent, a complexing agent and a solvent; 2) mixing the alkaline solution, The manganese source solution and the complexed iron source solution are added to the bottom solution to carry out a co-precipitation reaction to obtain the manganese-iron binary hydroxide precursor. The method of the invention realizes the uniform co-precipitation of manganese and iron in the wet system for the first time on the basis of manganese and iron, which are inexpensive and environmentally friendly metal elements, and overcomes the impurities caused by element segregation. Phase generation, uniform distribution at the atomic level between elements. |
