英文摘要Vanadium-based MXenes are prospective as anode materials in energy-storage devices including lithium ion batteries (LIBs) but limited by their charge-discharge capacities. Herein, partially-etched V2AlxCTz with the average particle size of similar to 400 nm was synthesized using 40 wt% HF or mixed NaF+HCl solutions as etchants, respectively. V2AlxCTz etched by 40 wt% HF for 96 h at room temperature (RT) has more exceptional charge-discharge performances against mixed NaF+HCl solutions, with an average reversible capacity of similar to 450 mAh g(-1) at 0.1 A g(-1) in the 120 cycles and similar to 301.2 mAh g(-1) at 0.5 A g(-1) after 200 cycles in LIBs. The effect of etchants on electrochemical performances and lithium-ion (Li-ion) storage mechanism of V2AlxCTz was discussed comprehensively. Additionally, a Li-ion full cell using LiFePO4 as cathode has exhibited excellent electrochemical performance (150.4 mAh g(-1) at 0.1 C). This work illustrates that partially-etched V2AlxCTz with the submicro-sized distribution is also a promising anode material for LIBs. (C) 2021 Elsevier B.V. All rights reserved.
