| description | The invention provides a nickel-iron-manganese oxyhydroxide positive electrode precursor. The crystallite size D001 of the (001) crystal face of the nickel-iron-manganese oxyhydroxide positive electrode precursor is 10-25 nm. Compared with a traditional nickel-iron-manganese hydroxide (NiaFebMncOOH), the nickel-iron-manganese oxyhydroxide (NiaFebMnc (OH) 3) ternary sodium electric precursor has the advantages that the mass ratio of metal ions is higher and reaches 50-70%, and the yield of the process of converting the precursor into a positive electrode is increased to 5-15% under the same mass; and meanwhile, the retained OH can maintain a microscopic layered structure, so that the interplanar spacing of the (001) crystal face is maintained to be beneficial to the subsequent co-firing process with a sodium source and the embedding of sodium ions, and better performance is achieved.
