Abstract:

Facet engineering of electrode materials with a special facet provides a new strategy to enhance their electrochemical properties. In the present work, hierarchical TiO2-B composed of nanosheets with exposed {010} facets are successfully synthesized via a facial hydrothermal route. When used as an anode for lithium ion batteries, this material demonstrates high capacities, excellent rata capability and remarkable cycling performance. For instance, it displays a reversible capacity of 200.9 mA h g−1 after 200 cycles at a current density of 1.675 A g−1 (5 C). Furthermore, a full cell consisted of hierarchical TiO2-B composed of nanosheets with exposed {010} facets anode and LiFePO4 cathode exhibits a high capacity of 125.6 mA h g−1 after 1000 cycles at a current density of 2 A g−1. Such outstanding electrochemical properties of this material can be attributed to hierarchical structure and the presence of exposed {010} facets which provides favorable lithium transport channels. © 2018 Elsevier B.V.
