摘要: 应用水热法合成前驱物CaSn(OH)6,经高温煅烧而得CaSnO3. XRD、SEM、DSC-TGA表征其物相、表面形貌和相变过程,调节溶剂水和乙醇比例,可有效地控制前驱物的形态,从立方块到内凹立方块乃至枝状结构变化,高温煅烧前驱体可得到CaSnO3样品。CaSnO3电极比容量为334.4 mAh/g,呈现出优良的循环寿命。

关键词: CaSnO3, 煅烧, 锂离子电池

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 volumn 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.

Key words: CaSnO3, calcination, Li-ion battery.
