Precursor for Positive Electrode Active Material, Manufacturing Method Thereof, And Manufacturing Apparatus Thereof

Abstract

A manufacturing apparatus of a precursor for positive electrode active material includes a reactor configured to receive a reaction solution and produce a precursor for positive electrode active material through a co-precipitation reaction of the reaction solution, a filtration unit disposed inside the reactor and configured to discharge a filtrate excluding solids in the reaction solution to the outside of the reactor when the reaction solution reaches a predetermined solution level, an extraction unit configured to extract a portion of the reaction solution when the size of a precursor particle in the reaction solution reaches a predetermined size, and a storage tank configured to receive a reaction solution extracted from the reactor through the extraction unit. A method of manufacturing and the precursor are also provided.
