<P>PROBLEM TO BE SOLVED: To provide lithium-transition metal oxide powder in which a coating layer containing lithium niobate is formed on a part or an entirety of lithium-transition metal oxide particle surfaces and green compact resistance is low, and to provide a cathode active material for lithium ion batteries containing the lithium-transition metal oxide powder. <P>SOLUTION: Lithium-transition metal oxide powder is composed of lithium-transition metal oxide particles in which a part or an entirety thereof is coated with a coating layer containing lithium niobate. A carbon content of the lithium-transition metal oxide powder is equal to or smaller than 0.03 mass%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
