摘要:As intercalation-type anode materials for Li-ion batteries (LIBs), the commercially used graphite and Li4Ti5O12 exhibit good cycling and rate properties, but their theoretical specific capacities are too low to meet the ever-growing demands of high-energy applications such as electric vehicles. Therefore, the development of new intercalation-type anode materials with larger capacity is very desirable. Herein, we design and synthesize novel 3D hierarchical porous V2O3@C micro/nanostructures consisting of crumpled nanosheets, through self-reduction under annealing from the structurally similar VO2(B)@C precursors without the ad-dition of any other reducing reagent or gas. Excitingly, it is found for the first time through ex situ XRD technology that V2O3 is a new, promising intercalation-type anode material for LIBs with a high capacity. V2O3@C micro/nanostructures can deliver a large capacity of 732 mAh g(-1) without capacity loss at 100 mAg(-1) even after 136 cycles, as well as exhibiting excellent cycling and rate performances. The application of V2O3 for Na-ion batteries (NIBs) is elaborated for the first time, and excitingly, it is found that V2O3@C micro/nanostructures may be promising anode materials for NIBs.
