Abstract Zinc‐ion capacitors (ZICs) are emerging as a compelling choice for energy storage in future, promising high power and densities coupled with eco‐friendly characteristics. This work presents novel approach to enhance the performance of ZICs by employing one‐step solvothermal synthesis growth V‐MOF on surface V 2 CT X ‐MXene, followed annealing fabricate 3D cross‐linked VO /V ‐MXene‐x(VO /MXene‐x) composite. The unique structure demonstrates excellent conductivity redox reaction activity, which significantly shortens Zn 2+ diffusion path. Moreover, intertwined crystalline‐amorphous efficiently suppresses lattice volume expansion during (de)intercalation. Density functional theory (DFT) reveals that amorphous O 5 enhances conductivity, lowers capture barrier, improves charge transfer efficiency. introduction oxygen vacancies further electronic transport. /MXene‐4 composite exhibits specific capacity 336.39 mAh g −1 at 1 A , maintaining 213.06 10 indicating outstanding rate performance, along an density 356.27 Wh kg 1280 W . offers insights design electrode materials feature phases, providing valuable into ion transport mechanisms strategies kinetics.

Abstract Owing to the abundant reserves and low cost, sodium‐ion batteries (SIBs) have garnered unprecedented attention. However, their widespread adoption is hindered by scarcity of alternative anodes with fast‐charging capability high stability. To overcome this challenge, a SIB anode, N‐doped Bi/BiOCl embedded in carbon framework (Bi/BiOCl@NC) fast Na + transport channel ultra‐high structural stability, developed. During cycling ether electrolyte, Bi/BiOCl@NC undergoes remarkable transformation into 3D porous skeleton, which significantly reduces pathway accommodates volume changes. By employing density functional theory calculations simulate storage behavior structure, theoretically characterized barrier (0.056 eV) outstanding electronic conductivity. Such unique characteristics induce anode an capacity 410 mAh·g −1 at 20 A·g exhibit stability over 2300 cycles 10 . This study provides rational scenario for design will enlighten more advanced research promote exploitation SIBs.
