abstract in English:	C/Sn - SnO 2 nanocomposite was obtained in one step pyrolysis and carbore duction process, providing formation of tin - based nanograins encapsulated in carbon buffer matrix derived from plan t polysaccharide (potato starch). Electrical conductivity of t he obtained material was carried out within temperature range - 20÷ 40 ̊ C. Cyclic voltammetry (CV) and charge - discharge tests were pe rformed in Li/Li + /(C/Sn - SnO 2 ) R2032 - type coin cells within 0.02 ÷ 1 .5 V potential range. Furthermore , electrochemical impedance spectroscopy (EIS) was used to characterize electrochemica l properties of the nanocomposite. The C/Sn - SnO 2 anode material provided at least 538 mAh g -1 at C/20 – rate and revealed good coulombic efficiency and capacity retention in charge - discharge cell tests.
