Abstract

A negative electrode material [514] for lithium ion batteries according to one aspect of the present invention includes silicon fine particles [2] formed by grinding crystalline silicon [S2]. In a negative electrode material [514] for lithium ion batteries according to another aspect of the present invention, the intensity of a diffraction peak near 2 = 28.4 attributed to Si(111) is greater than the intensities of other diffraction peaks in X-ray diffraction measurement of the plurality of silicon fine particles [2] composed of crystalline silicon. By employing the negative electrode materials [514] described above, there can be provided a lithium ion battery having small variations in charge-discharge capacity even when charged/discharged repeatedly.
