| Abstract: | In this study the precursor CaSn(OH)6 was prepared via a hydrothermal process,and its composition,surface feature and phase-transition were characterized by XRD,SEM and DSC-TGA.The shapes of CaSn(OH)6 crystals were effectively controlled by adjusting the volume ratio of H2O and CH3CH2OH solvents.Perovskite CaSnO3 could be obtained by calcination of CaSn(OH)6 at 800 ℃.The reversible capacity of 334.4 mAh/g with good cycling stability could be achieved with the CaSnO3 electrode. |
