Characterization of SnO2 nanowires as an anode material for Li-ion batteries

Sn O 2 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 2133mAhg−1, which is much more than the theoretical total capacity of the bulk SnO2, 1494mAhg−1. During the succe...

Description
Summary:Sn O 2 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 2133mAhg−1, which is much more than the theoretical total capacity of the bulk SnO2, 1494mAhg−1. During the successive 15cycles, the reversible capacity stays in the range of 1250–700mAhg−1 with a capacity fading of 3.89%percycle at a constant current density of 0.5mAcm−2. These results demonstrate that SnO2 nanowires are a promising anode material for Li-ion battery applications.
