N2 - As cathodes for aqueous zinc ion batteries (ZIBs), vanadium-based materials have received a lot of attention in recent years because of their high theoretical capacities and suitable working potentials. However, the sluggish kinetics and volume expansion effects lead to their rapid capacity decay and poor rate performance. Herein, a novel strategy is proposed through the in-situ growth of one-dimensional hollandite-type VO1.52(OH)0.77 nanorod arrays on flexible carbon fiber cloth as ZIBs cathode material. The synergistic effect between the hollandite-type tunnel structure and the functional group-modified conductive collector, not only accelerates the charge transfer rate and increases zinc ion intercalation capacity but also enhances the structural stability of the electrode by improving the interface stability and alleviating the detachment between the VO1.52(OH)0.77 nanorod arrays and the conducting substrate during the charge/discharge process. Benefitting from these merits, as-prepared VO1.52(OH)0.77 achieves an impressive reversible capacity of 305.6 mAh g−1 at 100 mA g−1 and ultralong cyclic stability (96.4% retention over 1000 cycles). This work reveals a concise approach to the construction of hollandite-type and demonstrates that the structural stability of vanadium-based oxide cathodes can be significantly enhanced by elegant structural design, thereby improving their Zn ion storage performance.
