Highly lithiophilic Ti3C2Tx-MXene anchored on flexible carbon foam scaffolds toward dendrite-free lithium metal anode

Herein, a lithiophilic Ti3C2Tx MXene modified the carbon foam (CF@Ti3C2Tx-MX) is elaborately designed to regulate Li nucleation behaviors and mitigate volume change of lithium metal anode (LMAs) for harvesting highly-stable LMBs.

Thereinto, the 3D CF skeleton with a high specific surface area not only reduces the local current density for avoiding concentration polarization, but also provides enough space for relieving volume expansion during the cycling. More importantly, the excellent lithiophilicity of Ti3C2Tx-MX endowed by the abundant functional groups can effectively reduce the Li nucleation overpotential, guide uniform Li deposition without Li dendrites formation, and maintain a stable interface on the anode surface.
