▎ 摘 要
We have designed a unique hybrid structure by directly growing ultrathin anatase TiO2 nanosheets onto graphene support for fast lithium storage. With exposed (001) high-energy facets, these TiO2 nanosheets serve as ideal hosts for fast and efficient lithium storage. On the other hand, the graphene support serves as a highly conductive substrate that is beneficial to the high-rate performance.
