2007 Electrodes F 3000 Si/SnSb Alloy Composite as High Capacity Anode Materials for Li-Ion Batteries. — The title alloy is synthesized from a mixture of SnO 2 , Sb 2 O 3 , Si, and carbon powder (Ar, 900 °C, 2 h) and characterized by XRD and SEM. The Si/SnSb composite elec- trode exhibits a high specific capacity and a good cycling stability due to its relatively large particle size and multiphase characteristics. A specific capacity of 1017 mAh/g with an initial capacity loss of 120 mAh/g is achieved for the synthesized Si/SnSb com- posite. Because of the excellent electrochemical performance the microscaled Si/SnSb alloy composite is a promising anode material for the new generation of Li-ion batter- ies. — (GUO, H.; ZHAO*, H.; YIN, C.; QIU, W.; J.
