采用溶剂热法合成了一种新型的纳米复合材料，该材料由单晶介孔TiO 2颗粒（TiO 2 mesocage）和碳纳米管（CNTs）构成。这种独特的杂化结构赋予了纳米复合材料简单的离子和电子传输途径、丰富的表面活性位点和高的结构稳定性。结果表明，CNTs-TiO 2介笼具有高容量、优异的倍率性能和超稳定的长期循环性能等优异的电化学储锂性能。
A novel nanocomposite based on mesoporous single-crystalline TiO2 particles (TiO2 mesocages) threaded with carbon nanotubes (CNTs) has been successfully synthesized via a facile solvothermal method. The unique hybrid architecture endows the nanocomposite with facile ion and electron transport pathways, abundant active surface sites and high structure robustness. As a result, remarkable electrochemical lithium storage properties in terms of high capacity, excellent rate capability and ultra-stable long-term cycling performance have been achieved by the CNTs-threaded TiO2 mesocages.
