Abstract

AbstractMXenes, an innovative class of two‐dimensional (2D) materials composed of transition‐metal carbides and/or nitrides, have garnered significant interest for their potential in energy storage and conversion applications, which is largely attributed to their modifiable surface terminations, exceptional conductivity, and favorable hydrophilic characteristics. MXenes show various ion transport behaviors in applications like electrochemical catalysis, supercapacitors, and batteries, encompassing processes like electrostatic adsorption of surface ions, redox reactions of ions, and interlayer ion shuttle. This review aims to present a summary of advancements in the comprehension of ion transport behaviors of Ti3C2T
