Abstract
MXenes, a new class of two-dimensional (2D) materials, have drawn special attention as potential anode materials for lithium-ion batteries (LIBs) in the last decade. However, the productization is primarily restricted by the scalable preparation of their parent MAX phases. Moreover, decreasing the particle size of the precursor powder could dramatically enhance the etching efficience. Furthermore, the fine-grained MAX phases are beneficial for improving the electrochemical performance of MXenes. Therefore, herein we report a facile and high-efficiency method to synthesize submicron-sized TiAlC powder in molten (Na,K)Cl in large quantities. As a result, TiCT MXene powder was attained by almost complete removal of Al layer from the above precursor in 8% HF solution for 2 h at room temperature. The as-prepared TiCT MXene exhibited superior performance as an anode material for LIBs with a sustainable discharge capacity of ∼260 mAh‧g at 100 mA‧g in 120 cycles and a discharge capacity of 216 mAh‧g at 500 mA‧g with an excellent capacity retention of 96.13% after 540 cycles. The prominent performance of TiCT as an anode material for LIBs is due to the introduction of high-density surface functional groups during etching of the submicron-sized TiAlC and enhanced density of edges, which provide more effective adsorption sites for Li ions.
