Stretchable MXenes for Supercapacitors: A Review

The rapid advancement of wearable and implantable technologies drives the need for stretchable energy storage systems with strong electrochemical and mechanical performance. MXenes, 2D transition metal carbides/nitrides, are promising materials due to their high conductivity, tunable chemistry, and scalable fabrication. While effective in flexible devices, adapting MXenes for stretchable architectures remains a key challenge. This review highlights emerging strategies to develop MXene‐based stretchable composites through various designs for supercapacitors. However, challenges such as interfacial stability, scalability, and durability under repeated deformation persist. We have summarized the transitioning of MXene‐based stretchable composites from lab‐scale to commercial products. Finally, this work outlines a path toward next‐generation, stretchable energy storage solutions for wearable electronics, robotics, and othertechnologies.
