Lithium molybdate coated modified lithium manganate material as well as preparation method and application thereof

The invention provides a lithium molybdate coated modified lithium manganate material as well as a preparation method and application thereof, and belongs to the technical field of lithium ion batteries. The lithium molybdate coated modified lithium manganate material provided by the invention comprises molybdenum-doped lithium manganate and lithium molybdate coated on the surface of the molybdenum-doped lithium manganate. The molybdenum element is used for doping the lithium manganate, so that the structural defect of the lithium manganate can be effectively improved, and the structural stability of the lithium manganate is improved; the surface of molybdenum-doped lithium manganate is coated with a layer of lithium molybdate, so that the side reaction between lithium manganate and electrolyte can be effectively reduced, and the cycling stability of the material in the cycling process is improved. The result of the embodiment shows that the specific discharge capacity of the lithium molybdate coated and modi
