Abstract

See full text

Composite carbon particles including a porous carbon material and a silicon component, the composite carbon particle having an average aspect ratio of 1.25 or less, and a ratio (ISi/IG) of a peak intensity (ISi) in the vicinity of 470 cm−1 to a peak intensity (IG) in the vicinity of 1580 cm−1 as measured by Raman spectroscopy of 0.30 or less, wherein the porous carbon material satisfies V1/V0>0.80 and V2/V0<0.10, when a total pore volume at a maximum value of a relative pressure P/P0 is defined as V0 and P0 is a saturated vapor pressure, a cumulative pore volume at a relative pressure P/P0=0.1 is defined as V1, a cumulative pore volume at a relative pressure P/P0=10−7 is defined as V2 in a nitrogen adsorption test, and has a BET specific surface area of 800 m2/g or more.
