Co-precipitation reactor and method of manufacturing material precursor for secondary battery using the same

A co-precipitation reactor for manufacturing a positive electrode active material precursor for a secondary battery, the co-precipitation reactor comprising:

• a reaction chamber having a plurality of suppliers configured to direct a reaction material and a pH adjusting material into the reaction chamber;
• a stirrer configured to be disposed in the reaction chamber;
• a drive motor configured to rotate the stirrer;
• a stirring shaft configured to receive power from the drive motor and rotate the stirrer;
• a first heater configured to heat an outside of the reaction chamber;
• a first controller configured to control the first heater;
• a second heater configured to heat an inside of the reaction chamber;
• and
• a second controller configured to control the second heater,
• wherein the second controller is configured to control the second heater to operate according to a temperature gradient of the reaction material and the pH adjusting material in a region adjacent to a center and adjacent to an exterior wall of the reaction chamber.
