通过一种简便的水热法结合简单的后煅烧工艺，以辛酸亚锡为锡源，葡萄糖为碳源，制备了一种多孔的Sn@C纳米复合材料。所制备的Sn@C纳米复合材料在用作锂离子电池负极材料时，表现出优异的电化学性能，具有高可逆容量、长循环寿命和良好的倍率性能。
A porous Sn@C nanocomposite was prepared via a facile hydrothermal method combined with a simple post-calcination process, using stannous octoate as the Sn source and glucose as the C source. The as-prepared Sn@C nanocomposite exhibited excellent electrochemical behavior with a high reversible capacity, long cycle life and good rate capability when used as an anode material for lithium ion batteries.
