  "textContent": "The present invention is directed to a silicon-containing particle for use as a negative-electrode active material of a non-aqueous electrolyte secondary battery, wherein a crystal grain size is 300 nm or less, the crystal grain size being obtained by a Scherrer method from a full width at half maximum of a diffraction line attributable to Si (111) and near 2θ=28.4° in an x-ray diffraction pattern analysis, and a true density is more than 2.320 g/cmand less than 3.500 g/cm. The invention provides silicon-containing particles for use as a negative-electrode active material of a non-aqueous electrolyte secondary battery that enable manufacture of a non-aqueous electrolyte secondary battery having an excellent cycle characteristics and a higher capacity compared with graphite types.",
