Method for Producing Coated Positive Electrode Active Material Particles for Lithium Ion Battery, Positive Electrode for Lithium Ion Battery, and Coated Positive Electrode Active Material Particle for Lithium Ion Battery

摘要

PROBLEM TO BE SOLVED: To provide a coated positive electrode active material particle for a lithium ion battery capable of suppressing a side reaction occurring between an electrolytic solution and a coated positive electrode active material particle and preventing an increase in an internal resistance value of the lithium ion battery. SOLUTION: The coated positive electrode active material particles for a lithium ion battery have at least a part of the surface of the positive electrode active material particles coated with a coating layer, and the coating layer comprises a polymer compound, a conductive auxiliary agent and ceramic particles. Coated positive electrode active material particles for lithium ion batteries. [Selection diagram] Fig. 1
