However, the interfacial issue becomes more pronounced in the 2D confined space. The strong hydrogen bonds between confined water molecules and surface \u2500O terminations of MXenes immobilize protons and hinder charge storage kinetics. Here, we introduce an edge\u2010coordination strategy to achieve precise electronic delocalization modulation in Ti\n                    <jats:sub>3<\/jats:sub>\n                    C\n                    <jats:sub>2<\/jats:sub>\n                    T\n                    <jats:italic>\n                      <jats:sub>x<\/jats:sub>\n                    <\/jats:italic>\n                    MXene by anchoring carboxyl\u2010functionalized carbon quantum dots (CQDs) at positively charged edges. The CQDs induce substantial electron delocalization on surface \u2500O sites, which simultaneously weakens rigid hydrogen bonds and facilitates interfacial charge transfer. This regulation establishes a dynamic hydrogen\u2010bond network that supports continuous Grotthuss\u2010type proton migration within the confined channels. Consequently, the optimized CQDs@MXene electrode delivers a volumetric capacitance of 2507.2 F cm\n                    <jats:sup>\u22123<\/jats:sup>\n                    , retains 65.8% at 1000\u00a0mV s\n                    <jats:sup>\u22121<\/jats:sup>\n                    , and maintains nearly 100% stability over 10\u00a0000 cycles.
