以无定形TiO 2微球为前驱体，制备了介孔TiO 2-Sn@C核壳微球。Sn被封装到TiO 2基质中，并且碳被包覆在外部。这种有趣的结构可以有效地缓冲体积变化和结构应力，从而有助于优异的长期循环稳定性和上级高速率循环能力。
Using amorphous TiO2 microspheres as precursors, we obtain mesoporous TiO2-Sn@C core-shell microspheres. Sn is encapsulated into a TiO2 matrix, and carbon is coated outside. This intriguing architecture can effectively buffer volume change and structural stress, thus contributing to excellent long-term cycling stability and superior high-rate cyclability.
