Abstract
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.
