COATED POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLES FOR LITHIUM ION BATTERIES, POSITIVE ELECTRODE FOR LITHIUM ION BATTERIES, AND METHOD FOR PRODUCING COATED POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLES FOR LITHIUM ION BATTERIES

摘要

Each one of coated positive electrode active material particles for lithium ion batteries according to the present invention is obtained by coating at least a part of the surface of a positive electrode active material particle with a coating layer that contains a polymer compound for coating and a conductive assistant. With respect to these coated positive electrode active material particles for lithium ion batteries, the coverage as determined by X-ray photoelectron spectroscopy is from 65% to 96%.
