Abstract
Abstract Antimony zinc alloy, Zn 4 Sb 3 , was studied as a potential material for negative electrodes of lithium-ion batteries. It was found that the reversible capacity of ball-milled Zn 4 Sb 3 in the first cycle reached 507 mA h g −1 and increased up to 580 mA h g −1 when the alloy was ball-milled with about 11.8 wt.% graphite additives. Ex-situ XRD analyses of the pure Zn 4 Sb 3 electrodes during cycling showed that several lithium-containing compounds such as LiZnSb, Li 3 Sb and LiZn have been formed successively during the insertion of lithium into Zn 4 Sb 3 . It was found that the ball-milled composite, Zn 4 Sb 3 /C 7 , possesses high initial reversible capacity, small voltage hysteresis and good capacity retention, which make this material an interesting potential electrode for lithium-ion batteries.
