Synergistic Design of MXene Architectures for Mechanically Robust and High‐Performance Flexible Batteries and Supercapacitors

open access: yesEcoEnergy, EarlyView.
This review article illustrates the diverse applications of MXene‐based architectures in flexible energy storage devices, including supercapacitors and various battery chemistries such as Li‐ion, Na‐ion, Zn‐ion, and Li‐S systems. At the core, MXenes synergize with carbon materials, metal oxides, and porous frameworks to construct mechanically resilient
