Application Number: JP,2022-111204
Category (FI): H01M4/525,H01M4/131,H01M4/13,H01M4/36@C
Stage: PROBLEM TO BE SOLVED: To provide coated positive electrode active material particles for a lithium-ion battery capable of producing an electrode having good powder flowability (low cohesion) and low surface roughness and a battery having excellent rate characteristics.SOLUTION: The coated positive electrode active material particles for a lithium-ion battery are formed by coating at least a part of the surface of the positive electrode active material particles for a lithium-ion battery with a coating layer. The coating layer includes a polymer compound and conductive filler having a glass transition temperature of 20degC or less. The ratio of a loose bulk density to a hard bulk density (loose bulk density/hard bulk density) is 0.75 to 0.95.SELECTED DRAWING: None (Grant)
