Abstract

The present invention relates to a method for preparing a lithium iron phosphate-based positive electrode active material. The method for preparing a lithium iron phosphate-based positive electrode active material comprises the steps of: (A) dry-pulverizing iron phosphate (FePO₄) and a carbon-containing coating raw material; (B) dry-mixing a lithium-containing raw material, the pulverized iron phosphate, and the pulverized carbon-containing coating raw material to prepare a reaction mixture; (C) compressing the reaction mixture into a pellet form; and (D) sintering the pellet-form reaction mixture to prepare a sintered product.
