Method of preparing positive electrode active material precursor for lithium secondary battery

Abstract

A method for manufacturing a positive electrode active material precursor for a lithium secondary battery is provided. The method comprises preparing a metal raw material, forming a reaction solution comprising the metal raw material, and coprecipitating a metal hydroxide precursor, wherein the reaction solution further comprises an additive, and wherein the additive comprises a colloidal flocculant. The method enables the manufacture of a positive electrode active material having a high level of microstructural orientation that facilitates ion diffusion throughout the electrode material and leads to batteries having significantly improved electrochemical properties.
