摘要

具有稳定晶体结构和快速 Zn2+ 储存能力的氧化钒阴极材料对于在水性锌离子电池中实现出色的电化学性能极为重要。本研究采用一步水热法将双金属离子插层到氧化钒的夹层中。预插层的铜离子作为支柱钉住氧化钒(V-O)层,为 Zn2+ 的快速扩散建立了稳定的二维通道。锰离子在 V-O 层间的占据进一步扩大了层间距,增加了氧缺陷(Od)的浓度,从而促进了 Zn2+ 的扩散动力学。因此,制备的 Cu0.17Mn0.03V2O5-□-2.16H2O 阴极在室温和低温环境下都具有出色的 Zn 储存能力(例如,室温下为 440.3 mAh g-1,-60°C 下为 294.3 mAh g-1)。重要的是,它的循环寿命长,在-60°C、2 A g-1 的条件下循环 2500 次,容量保持率高达 93.4%。此外,通过操作X射线粉末衍射和原位拉曼表征,还揭示了放电/充电过程中的可逆插层化学机制。3d 过渡金属掺杂策略为开发优异的室温/低温钒基阴极材料提供了解决方案。

Building stabilized Cu0.17Mn0.03V2O5−□·2.16H2O cathode enables an outstanding room-/low-temperature aqueous Zn-ion batteries

Vanadium oxide cathode materials with stable crystal structure and fast Zn2+ storage capabilities are extremely important to achieving outstanding electrochemical performance in aqueous zinc-ion batteries. In this work, a one-step hydrothermal method was used to manipulate the bimetallic ion intercalation into the interlayer of vanadium oxide. The pre-intercalated Cu ions act as pillars to pin the vanadium oxide (V-O) layers, establishing stabilized two-dimensional channels for fast Zn2+ diffusion. The occupation of Mn ions between V-O interlayer further expands the layer spacing and increases the concentration of oxygen defects (Od), which boosts the Zn2+ diffusion kinetics. As a result, as-prepared Cu0.17Mn0.03V2O5−□·2.16H2O cathode shows outstanding Zn-storage capabilities under room- and low-temperature environments (e.g., 440.3 mAh g−1 at room temperature and 294.3 mAh g−1 at −60°C). Importantly, it shows a long cycling life and high capacity retention of 93.4% over 2500 cycles at 2 A g−1 at −60°C. Furthermore, the reversible intercalation chemistry mechanisms during discharging/charging processes were revealed via operando X-ray powder diffraction and ex situ Raman characterizations. The strategy of a couple of 3d transition metal doping provides a solution for the development of superior room-/low-temperature vanadium-based cathode materials.
