摘要	Vanadium oxides (VOx) feature the potential for high-capacity Zn2+ storage, which are often preintercalated with inert ions or lattice water for accelerating Zn2+ migration kinetics. The inertness of these preintercalated species for Zn2+ storage and their incapability for conducting electrons, however, compromise the capacity and rate capability of VOx. Herein, Ni-BTA, a 1D conductive metal-organic framework (c-MOF), is intercalated into the interlayer space of VOx by coordinating organic ligands with preinserted Ni2+. The intercalated Ni-BTA improves the conductivity of VOx by pi-d conjugation, facilitates Zn2+ migration by enlarging its interlayer spacing, and stabilizes the crystal structure of VOx as interlayer pillars, thus simultaneously enhancing the material's rate capability and cycling stability. Meanwhile, a dual reaction mechanism of Zn2+ storage, i.e., the redox of V5+/V3+ in VOx and the rearrangement of chemical bonds (C(sic)N/C-N) in Ni-BTA, collaboratively contributes to an enhanced capacity. Consequently, this Ni-BTA-intercalated VOx material exhibits a high Zn2+ storage capacity of 464.2 mAh g(-1) at 0.2 A g(-1) and an excellent rate capability of 272.5 mAh g(-1) at 5 A g(-1). This work provides a general strategy for integrating c-MOFs with inorganic cathode materials to achieve high-capacity and high-rate performance.
