<P>PROBLEM TO BE SOLVED: To provide a composite particle for an electrode which can form the electrode having superior electrode characteristics easily and surely even when a binder is used as a constituent material, and to provide its manufacturng method. <P>SOLUTION: The composite particle P10 for the electrode contains particles P1 composed of an electrode active material, particles P2 composed of a conductive assistant, and particles P3 composed of the binder which can bind the particles P1 and the particles P2. The particle P10 is produced through a granulating process in which the particles P1 are integrally granulated with the conductive assistant and the binder. The granulating process comprises a process for preparing a raw material liquid containing the binder, the conductive assistant and a solvent, a process for generating airflow in a fluidizing vessel and fluidizing the particles P1 by inputting the particle P1 in the airflow, and a process for spraying the raw material liquid into the fluidized bed to make the raw material liquid adhere to the particles P1 and drying the particles to remove the solvent from the raw material liquid which is adhered to the surfaces of the particles P1, making the particles P1 and the particles P2 adhere with the binder. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
