Abstract Chemical manipulation of surface functional groups on two‐dimensional transition metal carbides and/or nitrides (MXenes) provides a wide range design and application prospects. However, achieving rapid targeted modification remains significant challenge. Herein, we propose general strategy to swiftly shear customize Ti 3 C 2 T x −MXene via the flash Joule heating (FJH) reaction within 1 s. Successfully, MXenes with 9 target terminations, including VII A (F, Cl, Br, or I), VI (O, S, Se), V (N P), either single multiple, are synthesized, content up about 76 %. The impact these terminations is systematically analyzed electrochemical performance, demonstrating that have higher activity than A. Particularly, N‐, S‐, O‐terminated exhibit enhanced specific capacities undecayed cycling performance. These findings offer valuable insights for engineering performance optimization materials.
