Abstract

Abstract : Binding TiO2 -B nanocrystals with N-doped carbon promotes interfacial lithium storage, leading to a high-capacity and long-life anode. Abstract : An effective strategy of binding TiO2 -B nanosheets with N-doped carbon is developed to construct highly stable TiO2 -B (001)|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 ∼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.
