| titleOfInvention | Modified lithium-rich manganese-based positive electrode material and preparation method and application thereof |
| abstract | The invention relates to a modified lithium-rich manganese-based positive electrode material and a preparation method and application thereof, wherein the chemical formula of the modified lithium-rich manganese-based positive electrode material is Li 2 Mn 1‑y M y O 2 X, wherein, 0<y<1, M is + 4-valent transition metal, X is halogen element, and Mn is + 2-valent; the preparation method comprises the following steps: dissolving a manganese source, an M source and an alkali metal citrate in ammonia water to form a complex solution; adding a lithium source and a fluorine source into the complex solution to obtain a mixed solution; freeze-drying the mixed solution to obtain a precursor; and heat-treating the precursor in a protective atmosphere to obtain the modified lithium-rich manganese-based positive electrode material. The positive electrode material rich in lithium manganese base reduces the valence state of Mn in the obtained modified positive electrode material rich in lithium manganese base and reduces the reaction activity of O by introducing + 4-valence transition metal ions and halogen element ions, thereby improving the reversible specific capacity and stability of the material. |
