METHOD FOR MANUFACTURING COMPOSITE MATERIAL FOR POSITIVE ELECTRODE OF LITHIUM BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a composite material for a positive electrode of a lithium battery which is particularly excellent in high-rate discharge performance.

SOLUTION: This method for manufacturing a composite material for a positive electrode of a lithium battery containing a positive electrode active material and a conductive substance comprises: a composite particle-forming step wherein composite particles containing the positive electrode active material and the conductive substance 1 are obtained by removing a solvent from slurry obtained by dispersing at least the positive electrode active material and the conductive substance 1 in the solvent up to a forcibly dispersed state; and a mixing step wherein at least the composite particles are mixed with a conductive substance 2 having an aspect ratio of 2-10.
