The purpose of this research is to develop tin oxide electrode for lithium ion polymer battery. We have investigated cyclic voltammetry and charge/discharge cycling of SnO2/SPE/Li cells. The first discharge capacity of SnO2 anode was 612mAh/g. The discharge capacity of SnO2 anode was 560 and 376mAh/g at 2nd and 15th cycle at room temperature, respectively. The SnO2 composite anode with PVDF-PC-EC-LiClO4 electrolyte showed good cycling performance.
