In this work, the hydrothermal method was employed to produce SnO₂/rGO as anode material. Nanostructured SnO₂ was prepared to enhance reversibility and to deal with the undesirable volume changes during cycling. The SnO₂/rGO hybrid exhibits long cycle life in lithium-ion storage capacity and rate capability with an initial discharge capacity of 1327 mAh/g at 0.1 C rate. These results demonstrate that a fabricated SnO₂/rGO matrix will be a possible way to obtain high rate performance.
在本工作中，采用水热法制备了SnO₂/rGO作为阳极材料。制备了纳米结构的SnO₂以提高可逆性并应对循环过程中不良的体积变化。SnO₂/rGO复合材料在锂离子存储容量和倍率性能方面表现出长循环寿命，在0.1 C倍率下的初始放电容量为1327 mAh/g。这些结果表明，制备的SnO₂/rGO基体将是获得高倍率性能的一种可能途径。
