Patent ID: 8426064

Claim:
A process for producing a composite material for positive electrodes of lithium batteries, which comprises composite particles containing positive electrode active material particles and fibrous carbons, the process including: Step 1 of obtaining a slurry containing a solvent, and the positive electrode active material particles and the fibrous carbons contained in a dispersed state in the solvent; and Step 2 of subjecting the slurry obtained in Step 1 to spray granulation to obtain granules containing the positive electrode active material particles and the fibrous carbons, wherein the slurry further contains a dispersing agent in Step 1, the positive electrode active material particles are supported by the fibrous carbons in the granules obtained in Step 2, and further comprising Step 3 of removing the dispersing agent from the granules in or after Step 2 to obtain composite particles, wherein Step 3 is a step of washing the granules with a solvent capable of dissolving the dispersing agent to remove the dispersing agent, thereby obtaining composite particles.
