Abstract

See full text

Disclosed are 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.
