POWER-TYPE NICKEL COBALT LITHIUM MANGANESE OXIDE MATERIAL, AND PREPARATION METHOD THEREFOR AND USES THEREOF

摘要

The present invention relates to the technical field of preparation of a nickel cobalt lithium manganese oxide positive electrode material. Disclosed are a power-type nickel cobalt lithium manganese oxide material and a preparation method therefor and uses thereof. The preparation method comprises: adding an organic acid into a mixed aqueous solution of a lithium source, a nickel source, a cobalt source and a manganese source, aging, obtaining a sol precursor, obtaining a gel fiber through electrospinning, and obtaining the power-type nickel cobalt lithium manganese oxide material after calcination. In the present invention, the nickel cobalt lithium manganese oxide material of a nano-fiber structure is prepared by using a sol-gel electrospinning method, and the nickel cobalt lithium manganese oxide material of a nano-fiber structure has a uniform structure size, thereby effectively reducing surface energy, and improving a capacity of lithium ions.
