Abstract

To improve performance. A negative electrode material is a negative electrode material for a battery, and includes carbon, tungsten trioxide, and silicon particles () including silicon, and in the silicon particles (), a ratio of the amount of Si in Si2p derived from elemental silicon to the amount of Si in Si2p derived from SiOin a surface layer is 3 or more, on an atomic concentration basis, as measured by X-ray photoelectron spectroscopy.
