Silica doped tin oxide composite anodes for lithium-ion batteries
- 122 Downloads
Silica doped tin oxide composites prepared by a sol gel method have been studied as negative electrode materials for lithium-ion batteries. The composite powders fired at 500 °C were analysed by means of XRD and SEM and showed that the composite consists of a blend of crystalline and amorphous structure with different particle size distribution. The electrochemical properties of this anode material were examined by charge-discharge measurements and cyclic voltammetry. The silica doped tin oxide composite anode, which was cycled between 0.1 to 2.0 V, showed a reversible capacity of 270 mAh/g.
