The application discloses a modified non-woven fabric and a preparation method thereof. The method is characterized in that graphene oxide and graphene are prepared into a mixed multi-layer graphene spraying liquid through ultrasonic intercalation, and then the mixed multi-layer graphene spraying liquid is adhered to a non-woven fabric through a spraying process to modify the non-woven fabric. The modified non-woven fabric is not easy to fall off, is stable in structure, can effectively avoid tearing of fibers of the non-woven fabric in a stretching process, and improves the overall breaking strength of the non-woven fabric.

The invention relates to the technical field of batteries, and discloses a preparation method of a lithium nickel manganese oxide positive electrode active material, a battery monomer, a battery device and a power utilization device. The lithium nickel manganese oxide positive electrode active material in the battery monomer comprises a substrate and a coating layer arranged on the surface of the substrate; the matrix comprises single-crystal lithium nickel manganese oxide, the single-crystal lithium nickel manganese oxide is a flaky particle, the length of the flaky particle is 1-5 [mu] m, the width is 1-5 [mu] m, and the thickness is 0.25-1 [mu] m; the coating layer comprises lithium-based oxysalt and / or oxide containing an M element, and the M element is selected from one or more of silicon, boron, aluminum and titanium; in the matrix surface layer, the content of the M element is less than or equal to 100 ppm; wherein the substrate surface layer refers to an area which vertically extends 200nm from the surface of the substrate to the interior of the substrate. The battery monomer provided by the embodiment of the invention has relatively high rate capability and relatively good cycle performance.
