A method for manufacturing cathode particles coated with a continuous glass phase layer using a wet one-step sintering process.

Abstract

A method for manufacturing cathode particles coated with a continuous glass phase layer using a wet one-step sintering process includes the following steps: placing a lithium source, a glass phase precursor, and a dispersion into a mixer for mixing and grinding to form a first precursor slurry; placing a nickel-cobalt-manganese precursor into the first precursor slurry and thoroughly stirring and mixing to form a second precursor slurry; thoroughly stirring and mixing the second precursor slurry and then drying it to obtain precursor powder; subjecting the precursor powder to aerobic sintering, wherein the lithium source first melts and reacts with each of the nickel-cobalt-manganese precursors to form multiple NCM (lithium nickel cobalt manganese oxide) particles; the glass phase precursor forms a glass phase layer that coats the outer surface of each NCM particle, thereby forming the multiple cathode particles.
