Evaluation of MXene Deposition Methods on Activated Carbon Cloth for Enhanced Electrochemical Performance

MXene‐based electrodes have gained significant attention among different materials due to their unique intrinsic 2D layered structure, excellent conductivity, large surface area, and tunable surface, making them highly promising for advanced electrochemical applications. However, the efficacy of MXene electrodes is strongly dependent on the deposition techniques employed, which affect adhesion, uniformity, and electrochemical performance. Despite several studies on MXene‐based materials for energy applications, a comprehensive comparative analysis of deposition techniques to optimize electrode performance is still lacking in the literature. This study presents a systematic comparison between two commonly used MXene deposition techniques, electrophoretic deposition (EPD) and drop coating, for effective binding of MXene onto activated carbon cloth. Morphological, structural, and electrochemical analysis revealed that drop coating produced a uniform and adherent material layer, exhibiting lower internal resistance (1.79 Ω) and superior electrochemical activity compared to EPD (33.32 Ω). The MXene‐coated electrode enhanced ion transport and proton accessibility, demonstrating improved capacitance under identical material loading. Furthermore, chronoamperometric analysis highlights that the drop‐coated MXene electrode maintains over 85% current retention during prolonged operation, confirming its superior operational stability. These findings highlight the crucial role of deposition method improvement in electrode design and provide a practical route for high‐performance MXene‐based electrodes, enabling various applications.
