摘　　要：Tin - based composite oxides anode materials for lithium - ion thin - film batteries have been prepared by high - erergy ball - milling method.The phase evolution,morphology and electrochemical properties of the materials were investigated by X - ray diffraction,scanning electron microscopy,cyclic voltammetry,charge - discharge test.The re - sults show milling can cause the stannous oxide crystal losing its crystalli ne character and becoming the amor - phous structure.The particle size of the powder materials decreases with the increase of ball - milling time.The re - versible specific capacity is more than578mAh·g -1 and its capacity loss per cycle is only0.31%after being cy - cled20times,which indicates that the material prepared by this method has go od electrochemical behavior and may be a candidate for the next generation anode materials for lithiumn ion batteries.Tin - based composite oxides anode materials for lithium - ion thin - film batteries have been prepared by high - erergy ball - milling method.The phase evolution,morphology and electrochemical properties of the materials were investigated by X - ray diffraction,scanning electron microscopy,cyclic voltammetry,charge - discharge test.The re - sults show milling can cause the stannous oxide crystal losing its crystalli ne character and becoming the amor - phous structure.The particle size of the powder materials decreases with the increase of ball - milling time.The re - versible specific capacity is more than578mAh·g -1 and its capacity loss per cycle is only0.31%after being cy - cled20times,which indicates that the material prepared by this method has go od electrochemical behavior and may be a candidate for the next generation anode materials for lithiumn ion batteries.
