Characterization of SnO2 nanowires as an anode material for Li-ion batteries -: art. no. 113108

SnO2 nanowires synthesized by thermal evaporation method are investigated as a possible anode electrode for Li-ion batteries. In the first discharge process, the capacity of Li ions is 2133 mA h g(-1), which is much more than the theoretical total capacity of the bulk SnO2, 1494 mA h g(-1). During the successive 15 cycles, the reversible capacity stays in the range of 1250-700 mA h g(-1) with a capacity fading of 3.89% per cycle at a constant current density of 0.5 mA cm(-2). These results demonstrate that SnO2 nanowires are a promising anode material for Li-ion battery applications.
