A SnO2 electrode material was successfully synthesized using the Pechini method and is of interest for potential use in lithium batteries. In this work, the effects of the calcination temperature on the fabrication of the SnO2 electrode material were investigated in detail. The architecture, morphology and crystal phase of the SnO2 electrode material were analyzed using SEM and XRD. It was found that a calcination temperature of 400°C produced a crystalline phase, and at 600°C, an excellent crystalline structure was produced. The grain size of the SnO2 electrode material is approximately 40 nm, as observed by XRD and SEM. The capacity of the SnO2 electrode material also increases with increasing calcination temperature and can reach a discharge capacity of 1800 mAh/g and a charge capacity of 710 mAh/g at 600°C. Furthermore, the capacity of the SnO2 electrode material remains at 40% after 12 chargedischarge cycles.
