COATED LITHIUM-NICKEL COMPLEX OXIDE PARTICLE AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide superior lithium-nickel complex oxide particles having lithium ion conductivity, which enable the suppression of impurity creation owing to absorption of moisture or carbonic acid gas because of its high environmental stability, and which are arranged so that a coating layer is not readily caused to exfoliate because a high adhesion is achieved.SOLUTION: A coated lithium-nickel complex oxide particle comprises: a lithium-nickel complex oxide particle; and alkylthiol group-containing molecules coating the surface of the lithium-nickel complex oxide particle. The coated lithium-nickel complex oxide particle has an electrical conductivity and an ionic conductivity. The compound enables the suppression of transmission of moisture or carbonic acid gas. Hence, it is possible to provide coated lithium-nickel complex oxide particles for a lithium ion battery positive electrode active material, which are superior as those for lithium ion battery use.SELECTED DRAWING: None
