    Abstract: An object of the present invention is to provide carbon-coated Si—C composite particles capable of maintaining a high Si utilization rate and suppressing deterioration of initial coulombic efficiency due to oxidation over time of a lithium-ion secondary battery.
    The carbon-coated Si—C composite particles of the present invention includes Si—C composite particles containing a carbon material and silicon; and a carbonaceous layer present on surfaces of the Si—C composite particles,



    wherein the carbon coverage thereof is 70% or more,
    wherein the BET specific surface area is 200 m2/g or less; wherein R value (ID/IG) is 0.30 or more and 1.10 or less and ISi/IG is 0.15 or less, when the peak attributed to Si is present at 450 to 495 cm−1 and the intensity of the peak is defined as ISi, in Raman spectrum of the carbon-coated Si—C composite particles: and
    wherein the full width at half maximum of the peak of a 111 plane of Si is 3.00 deg. or more, and (peak intensity of a 111 plane of SiC)/(peak intensity of the 111 plane of Si) is 0.01 or less, in the XRD pattern measured by powder XRD using a Cu-Kα ray of the carbon-coated Si—C composite particles.
