金属锡因其高的理论比容量（990 mAh/g）和体积比容量（7200 mAh/cm3），被公认为是很有应用前景的锂离子电池负极材料。但在充放电过程中存在易团聚、体积变化大等问题而导致循环性能差。最近我们研究发现采用超声化学法将SnO2纳米颗粒负载于有序介孔碳CMK-3的孔道中，可以大幅度提高SnO2材料的循环稳定性能。相关研究成果已发表在SCI收录的美国化学会著名期刊（ACS Applied Materials & Interfaces 2011, 3, 3704-3708）上。本项目将在前期研究基础上，采用超声化学和氢气还原相结合的方法将金属Sn纳米颗粒负载于三维有序介孔碳CMK-3的孔道中，制备具有三维有序介孔结构的新型Sn/CMK-3复合负极材料，在保持Sn良好循环稳定性能的同时，还可大幅度提高该复合材料的比容量。本项目正是在前期研究基础上的延伸、扩展和深化。相关研究还未见报道。

Tin anode has high theoretical specific capacity (990 mAh/g) and volume specific capacity (7200 mAh/cm3), and it was considered as a very promising anode materials for lithium-ion batteries. However,the aggregation of SnO2 nanoparticles and volume changes during the charging and discharging processes lead to poor cycling performance. Recently, we successfully prepared SnO2 nanoparticles inside the pore channels of CMK-3 ordered mesoporous carbon via sonochemical method. Electrochemical properties demonstrated that the ordered SnO2/CMK-3 nanocomposites can significantly improve the cycling stability of SnO2 anode. The studies have already been published in the journal of ACS Applied Materials & Interfaces. In this proposed study, we will synthesis of Sn nanoparticles inside the pore channels of CMK-3 three-dimensional ordered mesoporous carbon via sonochemical and hydrogen reduction method based on our previous studies. The three-dimensional ordered mesoporous Sn/CMK-3 nanocomposites are expected to possess higher reversible capacity and cycling stability than that of Sn anode. This proposed study is a further extension of our previous studies. No related studies has been reported.
