Insertion/extraction of lithium ions into/from Bi{sub 2}Se{sub 3} crystals was investigated by means of cyclic voltammetry. The process of insertion is reflected in the appearance of two bands on voltammograms at {approx}1.7 and {approx}1.5 V, corres

The reaction rate of Li intercalation into Bi2Se3−xSx single crystals (x = 0, 0.025 and 0.05) increases with an increasing sulfur content in the crystals. This effect has been explained qualitatively by a change in the bond polarity in the Bi2Se3 d
