The formation of surface Li-Sb alloy and its electronic structures are investigated with x-ray photoelectron spectroscopy (XPS). From the information on core-level shift of Sb 3d and Li 1s XPS spectra, the presence of charge transfer from Li to Sb is confirmed, while the chemical composition of formed alloy is estimated as Li3Sb. The density of states from valence band XPS shows a significant nonrigid part of band structures, suggesting strong covalent bonding between Li and Sb.
