Abstract
A new reductive co-precipitation route to synthesize a pure phase nanosized β-SnSb alloy in alcohol solution at low temperature is reported. The morphology and particle size of the β-SnSb alloy are influenced by temperature, stirring and the solvent. The nanosized β-SnSb alloy prepared by this method shows good electrochemical performance as an anode material for lithium ion batteries. The β-SnSb alloy transforms gradually into multiphase Li3Sb and LixSn with increased insertion of lithium ions. After extraction of the lithium ions, the original crystal structure of β-SnSb is restored, even after many cycles.Keywords
