Cover Picture: Enhancing Electrochemical Performance through Swift Functional Group Tuning of MXenes (Batteries & Supercaps 8/2024)

The Cover Feature shows how through the high-energy electric shock provided by flash Joule heat (FJH) technology, the primitive terminations on the MXene surface can be cut and modulated within 1 s. This strategy shows broad applicability in nine kinds of target termination: VII A (F, Cl, Br, or I), VI A (O, S, or Se), and V A (N or P), and can be successfully used in connection with the MX surface. Additionally, systematic electrochemical investigations demonstrate that VI A and V A terminations outperform VII A. More information can be found in the Research Article by Y.-Z. Fang, D. Cao and co-workers (DOI: 10.1002/batt.202400274).
