METHOD FOR PAREPARING POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM ION SECONDARY BATTERY

摘要

PURPOSE: A manufacturing method of a positive electrode active material for a lithium ion secondary battery is provided to simply mass-produce the positive electrode active material using an electro-spinning method. CONSTITUTION: A manufacturing method of a positive electrode active material for a lithium ion secondary battery comprises the following steps: forming a spinning solution by dissolving a positive electrode active material precursor and a conductive polymer; forming a nanofiber web by electro-spinning the spinning solution; and heat-processing the nanofiber web to form the positive electrode active material, and forming semi-graphite on the surface of the positive electrode active material.
