Printing‐Scalable Ti 3 C 2 T x MXene‐Decorated Janus Separator with Expedited Zn 2+ Flux toward Stabilized Zn Anodes

Abstract Separator modification has recently blossomed as an effective strategy to enable dendrite‐free Zn metal anodes. Nonetheless, the explored avenues are not conducive to mass production by far, and little attention is paid to the essence of separator regulation. Herein, a scalable Ti 3 C 2 T x MXene‐decorated Janus separator is designed by spray‐printing MXene nanosheets over one side of commercial glass fibre (GF). The thus‐derived MXene‐GF separator affords abundant surface polar groups, good electrolyte wettability, and high ionic conductivity, which is beneficial to homogenizing local current distribution and promoting Zn nucleation kinetics. It is noted that MXene‐GF displays adjustable dielectric…
