摘要

MXenes have been regarded as promising anode materials for Na-ion batteries due to their unique layered structures. Herein, the two-dimensional Ti₂CT_x with expanded interlayer by intercalation of dimethyl sulfoxide is designed as anode material for Na-ion storage. The as-prepared interlayer-expanded Ti₂CT_x delivered an initial discharge capacity of 486 mAh g⁻¹ and maintained a stable capacity of 176 mAh g⁻¹ after 250 cycles at 100 mA g⁻¹, which are much higher than those of the pristine Ti₂CT_x.
