Resumen de: WO2025246617A1
A lithium-rich manganese-based positive electrode material and a preparation method therefor and a use thereof, relating to the technical field of lithium batteries. By designing a gradient lithium distribution to stabilize a lattice oxygen framework of a material, the escape of lattice oxygen can be reduced, which not only can reduce gas generation but also can prevent the migration of transition metal ions and stabilize the crystal structure, thereby improving cycle stability. A layer of Mn3O4 material comprising oxygen vacancies is coated on an outer layer, so that oxygen escaping from the outermost layer is trapped, and irreversible phase transitions during charging and discharging can also be suppressed, thereby preventing an electrolyte from being in direct contact with a positive electrode material, and minimizing side reactions. The lithium-rich manganese-based positive electrode material can isolate lattice oxygen evolution, stabilize the crystal structure, and minimize side reactions, thereby enhancing electrochemical performance.
