Negative-electrode active material, negative electrode, and secondary battery |
| abstract |
A negative-electrode active material according to the present invention contains first negative-electrode active material particles containing a silicon-based material. A Si2p spectrum obtained by measuring the first negative-electrode active material particles under the condition of 0.6 V (vs. Li/Li + ) by X-ray photoelectron spectroscopy has a peak in the range of 99.0-105.0 eV inclusive, and the half-value width of the peak is 1.5-8.0 eV inclusive. |
