METHOD FOR PREPARING LITHIUM NICKEL COBALT MANGANATE BY MEANS OF REVERSE POSITIONING OF POWER BATTERY AND USE THEREOF

The present disclosure belongs to the technical field of lithium battery recovery, and provides a method for preparing lithium nickle cobalt manganese oxide by reverse positioning of a power battery and use thereof. The method first mixes and grinds a positive electrode tab and a slagging agent, then dries, cools, adds an aluminum powder, mixes well, conducts a self-propagating reaction to the mixed material, cools, takes a lower layer of rough nickel cobalt manganese alloy, grinds the rough nickel cobalt manganese alloy, adds an alkali liquor, then immerses, filters, takes the filter residue for washing and then dries, to obtain a nickel cobalt manganese alloy powder, adds a lithium salt solution to the porous nickel cobalt manganese alloy powder, mixes and drips an alkali liquor, ages, filters, takes a filter residue for washing and then dries, to obtain a mixed powder of precursor, sinters the mixed powder of precursor and cools, to obtain a lithium nickle cobalt manganese oxide. The present disclosure realizes a short distance connection of a scrapped material with a raw material, it has a short process flow, less consumption of raw and supplemental materials, low energy consumption, low treatment cost, less pollution emission, the whole process is environmental friendly.
