Abstract Layered vanadium phosphate (VOPO4•2H2O) is reported as a promising cathode material for rechargeable aqueous Zn2+ batteries (ZIBs) owing to its unique layered framework and high discharge plateau. However, its sluggish Zn2+ diffusion kinetics, the low specific capacity and poor electrochemcial stability remains a major issue in battery application. In this work, a group of phenylamine (PA)-intercalated VOPO4•2H2O with varied interlayer spacing (14.8, 15.6 and 16.5 Å) is synthesized respectively via a solvothermal method for cathode of aqueous ZIBs. The specific capacity is quite dependent on d-spacing in PA-VOPO4•2H2O system followed by an approximate linear tendency, and the maximum interlayer spacing (16.5 Å phase) results in a discharge capacity of 268.2 mAh•g-1 at 0.1 A•g-1 with a high discharge plateau of ~ 1.3 V and an energy density of 328.5 Wh•Kg-1. Both of the experimental data and DFT calculation identify that the optimal 16.5 Å spacing can boost fast Zinc-ion diffusion with an ultrahigh diffusion coefficient of ~ 5.7 × 10-8 cm-2•s-1. The intercalation of PA molecules also significantly increases the hydrophobility in the aqueous electrolyte, resulting in the inhibiting the decomposition / dissolution of VOPO4•2H2O and remarkably improved cycling stability over 2000 cycles at 5.0 A•g-1 with a capacity retention of ~200 mAh•g-1. Our study provides a feasible solution on the sluggish Zn2+ diffusion kinetics and poor cyclstability, and also shows a clear understanding on the interlayer chemistry of layered phosphates towards aqueous Zinc-ion storage.

MXene, a class of 2D transition metal carbide/nitride materials, has attracted widespread attention since its first discovery in 2011. Due to its high electronic conductivity, large specific surface area, good mechanical stability, and adjustable surface functional groups, MXene-based nanomaterials have shown great potential in energy storage devices. Meanwhile, zinc-based aqueous energy storage devices became a hotspot recently in energy storage field on account of their high security and low cost. In this review, the research progress on the preparation routes, preserving method, related structure and properties of MXene is first summarized. Followed by is an introduction of the recent state-of-the-art development of MXene-based electrodes for zinc-based aqueous energy storage devices, including zinc ion batteries (ZIBs), zinc-air batteries (ZABs), and zinc-halide batteries (ZHBs). Finally, the major bottleneck and perspectives for MXene-based nanomaterials in zinc-based aqueous energy storage devices are pointed out.
