Abstract
The present invention provides a method for producing a composite material for positive electrodes of lithium batteries which is particularly excellent in high-rate discharge characteristics. The method for producing a composite material for positive electrodes of lithium batteries, contains: a dispersing step of dispersing at least the positive electrode active material and the conductive material 1 in a solvent to be in a forcibly dispersed state; and a composite particle-forming step of obtaining composite particles containing the positive electrode active material and the conductive material 1 by a process for agglutinating the conductive material 1 together with the positive electrode active material in the solvent or by a process for removing the solvent.
