Stage: PROBLEM TO BE SOLVED: To provide coated negative electrode active material particles for a lithium ion battery that is resistant to cracking and can maintain good rate characteristics in an electrode that is compression molded using a roll press.SOLUTION: The coated negative electrode active material particles for lithium-ion batteries consist of a first coating layer coating at least part of the surface of the negative-electrode active material particles for lithium-ion batteries and a second coating layer coating at least part of the surface of the first coating layer. The ratio of the uncompressed bulk density to the compressed bulk density (uncompressed bulk density/compressed bulk density) is 0.40 to 0.62.SELECTED DRAWING: None (Grant)
