Core-shell structured Si-mesoporous TiO (Si@mTiO) composite nanospheres are designed and prepared via a step-by-step assembly method. Si@mTiO exhibit excellent lithium-storage properties when used as anode materials in lithium ion batteries. The reversible specific capacity is maintained at as high as 700 mA h g with no capacity decay even after 200 cycles at 1 A g.
通过逐步组装法设计并制备了核壳结构的硅-介孔二氧化钛(Si@mTiO)复合纳米球。当用作锂离子电池的负极材料时,Si@mTiO表现出优异的储锂性能。即使在1 A g的电流密度下循环200次后,可逆比容量仍保持高达700 mA h g,且没有容量衰减。
