摘要：

The SnO2-polyaniline(SnO2-PAn) composite was prepared by microemulsion polymerization method using aniline,ammonium peroxodisulfate and SnO2 as starting materials.The SnO2-PAn composite was characterized by X-ray diffractometer,scanning electron microscope and electrochemical techniques.The results show that PAn in the composites is amorphous.PAn formed in the reaction is deposited preferentially on the SnO2 particles,giving a SnO2-PAn composite,in which SnO2 is coated with PAn.SnO2-PAn composite shows a reversible capacity of 657.6 mA·h/g and the capacity loss per cycle is only 0.092% after 80 cycles,suggesting that SnO2-PAn composite is a promising anode material for lithium ion batteries.
