Title:
COATED POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLES FOR LITHIUM-ION BATTERY, POSITIVE ELECTRODE FOR LITHIUM-ION BATTERY, AND MANUFACTURING METHOD OF COATED POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLES FOR LITHIUM-ION BATTERY
Document Type and Number:
Japanese Patent JP2021150281
Kind Code:
A
Abstract:
To provide coated cathode active material particles for a lithium-ion battery that can suppress side reactions occurring between an electrolyte and the coated positive electrode active material particles and prevent the internal resistance of the lithium-ion battery from increasing.SOLUTION: A coated positive electrode active material particle for a lithium-ion battery has at least a part of the surface coated with a coating layer. The coating layer contains a polymer compound, a conductive aid, and ceramic particles.SELECTED DRAWING: Figure 1
