Phases hybriding and graphene-like TiO2 for high-performance Na-ion batteries

TiO2 with Graphene-like (TiO2-GL) structure and phases hybriding have been synthesized by hydrothermal method, which as anode material for SIB exhibited electrochemical performance even at a very high current density (∼100 mAh g−1 at 500 mA g−1 for 100 cycles). The superior electrochemical performance of TiO2-GL is due to the graphene-like structure provide more active sites for the Na+ insertion/extraction and promote the Na+ storage and electrochemical stability.221
