摘要	Ion pre -intercalation regulating the tunnel structure of electrode materials accelerates Zn2+ insertion kinetics to realize a high energy storage contribution of Zn-ion batteries. However, electrostatic interaction induced by the pre -intercalated cation and multivalent Zn2+ ions hinders the insertion of Zn2+/H+. In order to retain the negative interlayer surface, herein, OTf- anions were intercalated into the confined spacing by MXene via an electrochemical -driven method. Without changing the potential state of the interlayer spacings, OTf- anion induced a regulated interlayer distance, and a higher oxidation state of V based on the space occupation and the electron transfer mechanism. Consequently, the zinc ion storage capacity of V2CTx MXene increases from 125.2 to 288.7 mAh/g at 0.5 A/g. Interestingly, the negatively charged MXene surface was still intact, which presents lower diffusion barriers of the Zn2+ ions. The merits of anion pre -intercalation are highlighted and provide new insights into the ion storage function -oriented design of MXene.
