Abstract: Provided is a method for producing a positive polar precursor for a secondary battery. According to the present invention, the positive polar precursor for a secondary battery is produced using a positive polar material producing device comprising: a rotary cylinder which is rotated at a particular speed; an external cylindrical container which is concentrically formed with an agitating rod produced in the rotary cylinder and is formed on and fixed to the outer circumference of the rotary cylinder; and a feeding port which is equipped in the front end of the external cylindrical container so as to supply a positive polar precursor starting material, a chelating agent, and a pH adjusting agent. The method of the present invention comprises the steps of: supplying a positive polar precursor starting material, a chelating agent, and a pH adjusting agent overall having the concentration of 1.0-4.0 M through the feeding port; and co-precipitating the precursor starting material in a temperature range of 40-80°C by means of the rotation of the agitating rod. Through multiple additional feeding ports formed at the top of the positive polar material producing device, a precursor starting material having a different composition is added, and the rotation speed of the rotary cylinder may be 300-2000 rpm.
