Insertion/extraction of lithium ions into/from Bi2Se3 crystals was investigated by means of cyclic voltammetry. A part of Li+ ions is bound firmly in the crystal due to the formation of negatively charged clusters of the (LiBiSe2 center dot Bi3Se4-) type. A further extraction of Li+ ions from the van der Waals gap needs higher voltage due to the influence of negative charges localized on these clusters.
