Alkalized MXene/carbon nanotube composite for stable Na metal anodes.

ABSTRACT: Ti₃C₂ MXenes are emerging 2D materials and have attracted increasing attention in sodium metal anode fabrication because of their high conductivity, multifunctional groups and excellent mechanical performances. However, the severe self-restacking of Ti₃C₂ MXenes is not conducive to dispersing Na⁺ and limits the function of regulating sodium deposition. Herein, an alkalized MXene/carbon nanotube (CNT) composite (named A-M-C) is introduced to regulate Na deposition behavior, which consists of Na₃Ti₅O₁₂ microspheres, Ti₃C₂ MXene nanosheets and CNTs. Ti₃C₂ MXene nanosheets with large interlayer spaces and "sodiophilic" functional groups can provide abundant active
