    Abstract: Provided is a negative electrode active material for a lithium-ion secondary battery, comprising SiO x that has an intensity ratio A 1 /A 2 of 0.1 or less in spectra measured by a Fourier transform infrared spectrometer after subjecting the SiO x to evacuation treatment at 200°C, given that A 1 designates an intensity of a silanol group-derived peak which appears around 3400 to 3800 cm -1 , and A 2 designates an intensity of a siloxane bond-derived peak which appears around 1000 to 1200 cm -1 . It is preferred that x in the SiO x satisfies x 3 that may normally exhibit around 2100 cm -1 in spectra of the SiO x measured by a laser Raman spectrometer; and a ratio Y/X is 0.98 or less, given that X is a mole ratio of O to Si in the whole body of the SiO x , and Y is a mole ratio of O to Si in a surface vicinity of the SiO x . A lithium-ion secondary battery having high initial efficiency and charge/discharge capacity can be obtained by using this active material.

    Abstract: Provided is SiO x , wherein the amount of generated H 2 O gas detected in a temperature range of 200 to 800°C in a temperature-programmed desorption gas analysis is 680 ppm or less. The amount of the generated H 2 O is desirably 420 ppm or less. In addition, in a graph obtained by X-ray diffraction, the peak intensity P1 at a Si peak point exhibited near 2θ = 28° and the base intensity P2 at a peak point interpolated from the gradient of average intensities in the fore and aft positions near the peak point desirably satisfy (P1-P2)/P2≤0.2. This SiO x is used as a vapor deposition material, whereby the generation of splashing is suppressed in forming a film, and a vapor-deposited film having excellent gas barrier properties can be formed. In addition, this SiO x is used as a negative electrode active material, whereby high initial efficiency of a lithium-ion secondary battery can be maintained.
