Document Type and Number:

WIPO Patent Application WO/2010/026627

Kind Code:

A1

Abstract:

Disclosed is a method for producing an electrode material which has high discharge capacity at high charge/discharge rate and enables to realize sufficient charge/discharge rate performance. Also disclosed are an electrode material, an electrode and a lithium ion battery. Specifically disclosed is a method for producing an electrode material, which is characterized in that a slurry containing an electrode active material or a precursor of the electrode active material, and organic compounds each selected from at least two groups among the group A, group B and group C is sprayed and dried for forming a granule, and the thus-formed granule is fired at a temperature not less than 500˚C but not more than 1000˚C in a non-oxidizing atmosphere.
