Abstract
Sandwich-like, graphene-based mesoporous titania (G-TiO 2) nanosheets possess thin thickness, large aspect ratio, and mesoporous structure and show enhanced electrical conductivity. Such unique features provide numerous open channels for the access of electrolyte and facilitate the fast diffusion of lithium ions during the cycling processes. The graphene layer within each nanosheet can act as a mini-current collector, which is favorable for the fast electron transport in the electrode. As a consequence, G-TiO 2 nanosheets exhibit a ultrahigh rate capability and excellent cycle performance, holding great potential as a high-rate anode material for lithium storage.
