MXene, an emerging family of 2D transition metal carbides/nitride (MXene) materials, has attracted growing attention since its initial discovery in 2011. Owing to their extraordinary electrical conductivity, high mechanical stability, various functional groups, and large interlayer space, MXene and MXene-based nanomaterials have shown significant energy-storage capability. Firstly, research progress on the preparation strategies and properties of MXene are summarized. Secondly, the current state-of-the-art advances of MXene and MXene-based nanomaterials as advanced electrodes for energy storage devices, including lithium-ion batteries, sodium-ion batteries, potassium-ion batteries, and supercapacitors are reviewed. Finally, the key challenges and perspectives for further enhancing their electrochemical performances are also outlined. This Progress Report offers a reference and scientific inspiration for the design and preparation of high-performance MXene and MXene-based nanomaterials to meet the increasing need for next-generation energy-storage systems.
