Hybrid electrochemical devices (HEDs), which consist of one faradaic electrode and the other capacitive electrode, are considered as promising technologies owing to their high ion storage capacity, excellent rate performance, and long cyclability. In particular, MXenes have been extensively investigated as faradaic electrodes of HEDs owing to their fast electron and ion transport capabilities and diverse and tunable surface modifications. Herein, we provide a comprehensive review on the design strategies for enhancing the electrochemical performances of MXenes in HEDs, focusing on interlayer engineering, surface modification, and hybrid formation. We also summarize the recent advancement in the use of MXenes in metal-ion hybrid capacitors and hybrid capacitive deionization. Lastly, we address the current challenges for the practical application of MXene-based hybrid devices and offer our perspectives for future research directions. This review aims to provide insights into innovative MXene design strategies for electrochemical energy storage and water purification by elucidating the correlations between material chemistry and electrochemical properties of MXenes. © 2024 Science Press
