An effective strategy of binding TiO2-B nanosheets with N-doped carbon is developed to construct highly stable TiO2-B (001)vertical bar carbon interfaces with enhanced electronic conductivity and Li-uptake capability. The interfaces provide not only additional interfacial lithium-storage capability but also highly conductive pathways for the fast transport of electrons and lithium ions. The hybrid as an anode for lithium-ion batteries exhibits a safe operating potential window of similar to 1.5 V, superior rate capability with 180 mA h g(-1) at 6 A g(-1), and ultra-long cycle life of more than 2000 cycles, holding great promise for safe and high-power energy storage applications.
