Abstract

Nano-sized SnO2 powders with uniform morphology and narrow size distribution were prepared by spray pyrolysis from the spray solution with citric acid and ethylene glycol. The precursor powders with hollow and thin wall structure turned to nano-sized SnO2 powders with regular morphology after post-treatment process. The mean sizes of the SnO2 powders were changed from 56 and 350 nm when the post-treatment temperatures were changed from 600 and 1200°C. The initial charge capacities of the SnO2 powders were changed from 224 to 443 mAh/g when the post-treatment temperatures were changed from 600 to 1200°C. The SnO2 powders had the maximum charge capacity at a post-treatment temperature of 800°C.
