以碳球为硬模板合成SnO 2空心球，碳包覆后通过退火工艺得到碳包覆SnO 2/Sn杂化空心球。所制备的杂化微球分散良好，并被均匀的碳层包覆。碳包覆SnO 2/Sn杂化空心球电极具有较高的初始库仑效率（82.3%），高可逆容量和良好的循环稳定性（首次充放电容量分别为878.7和1061.6 mA h/g，在0.1 C下循环50次后，放电容量保持在401 mA h/g）和良好的倍率性能（0.1C时为1156.8mA h/g，0.2C时为752.2mA h/g，0.5C时为481.4mA h/g，1C时为289.5mA h/g，2C时为120.6mA h/g，更重要的是，当电流密度最终回到0.1C时，可恢复811.6mAh/g的容量）。
The hollow SnO2spheres were synthesized by using carbon spheres as hard templates, and then carbon-coated SnO2/Sn hybrid hollow spheres can be obtained through annealing process after carbon coating. The as-prepared hybrid spheres are well dispersed and coated with a uniform carbon layer. The carbon-coated SnO2/Sn hybrid hollow spheres electrode exhibits high initial Coulombic efficiency (82.3%), high reversible capacity and good cycling stability (the initial charge and discharge capacity of 878.7 and 1061.6 mA h/g was achieved and the discharge capacities maintained 401 mA h/g after 50 cycles at 0.1 C) and good rate performance (1156.8 mA h/g at 0.1 C, 752.2 mA h/g at 0.2 C, 481.4 mA h/g at 0.5 C, 289.5 mA h/g at 1 C, and 120.6 mA h/g at 2 C, and more importantly, when the current density finally backs to 0.1 C, a capacity of 811.6 mA h/g can be restored) for anode materials in lithium ion batteries due to the hierarchical porous structure, carbon coating and the presence of Sn.
