Abstract
Highlights • The interlayer spacing of Ti 2 CTx MXene can be enlarged by dimethyl sulfoxide intercalation. • The Ti 2 CT x MXene with expanded interlayer spacing delivered superior Na storage performance than the pristine Ti 2 CT x MXene. • Electrochemical kinetic analysis revealed a capacitive dominated sodium storage process. MXenes have been regarded as promising anode materials for Na-ion batteries due to their unique layered structures. Herein, the two-dimensional Ti 2 CT x with expanded interlayer by intercalation of dimethyl sulfoxide is designed as anode material for Na-ion storage. The as-prepared interlayer-expanded Ti 2 CT 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 Ti 2 CT x .
