METHOD FOR PRODUCING CATHODE ACTIVE MATERIAL PRECURSOR FOR LITHIUM SECONDARY BATTERY
摘要
PURPOSE: A method for producing a positive electrode active material precursor for a lithium secondary battery is provided to prepare a precursor of uniform particle size, thereby obtaining a positive electrode active material and a lithium secondary battery with excellent battery characteristics. CONSTITUTION: A method for producing a positive electrode active material precursor for a lithium secondary battery comprises the steps of: consecutively injecting nickel materials, one or more metal materials selected from the group consisting of transition metal and rare earth metal, complexing agent and precipitation agent in a reactor; obtaining a precursor through the reaction of the precipitation agent with a complex formed from the complexing agent and the metal materials and a precursor; and controlling the particle size of the precursor by controlling the nickel concentration in the reactor.
