Hierarchical TiO2-x imbedded with graphene quantum dots for high-performance lithium storage

Hierarchical TiO2-x imbedded with graphene quantum dots was synthesized through a facile synthetic route and investigated as an anode material for lithium-ion batteries. It delivers a high specific capacity and excellent rate capability (160.1 mA h g(-1) at 10 C after 500 cycles).
