METHOD FOR MANUFACTURING CATHODE MATERIALS IN SECONDARY BATTERY AND MIXER FOR CATHODE MATERIALS IN SECONDARY BATTERY

摘要

The present invention relates to a method for manufacturing a positive electrode material for a lithium secondary battery and a positive electrode material mixer for the secondary battery. The disclosed method for manufacturing the positive electrode material for the lithium secondary battery includes a step for weighing a desiccated raw material of a positive electrode for the lithium secondary battery in a correct mixture ratio, mixing and milling the raw material by charging the same into a mixer, calcinating the milled raw material at 800-900°C, and classifying the calcinated raw material. Also, disclosed is the mixer having a supply line partially comprising dual lines to homogeneously mix the raw material.
