The practical application of Si anodes is hampered by huge volume expansion during lithiation/delithiation
process, leading to poor cycling performance and electrode fracture. To overcome such weakness, a sandwichlike
Si/d-Ti3C2 hybrids are fabricated and show an excellent reversible capacity of 1130 mA h g−1 at a current
density of 500 mA g−1 after 200 cycles. Comparing with pristine Si, the improved electrochemical performance
of Si/d-Ti3C2 hybrids can be attributed to the fact that the d-Ti3C2 MXene can significantly enhance the electronic
conductivity of electrode and support integrity of electrodes. The Si/d-Ti3C2 hybrids perform their promising
prospect in lithium ion batteries.
