摘要
与锌离子水电池(AZIBs)相关的固有挑战,如低能量密度和缓慢的扩散动力学,对其作为储能系统的广泛应用构成了重大障碍。这些限制主要源于高质量阴极材料的非绿色和复杂的制备过程。在本研究中,我们提出了一种利用微波辅助球磨加速钒基插层纳米材料制备的方法,旨在解决制备正极材料过程中不可避免的长时间高温反应问题。在水溶剂条件下,仅用 40 分钟就合成了 Na2V6O16(NVO)纳米棒。这些纳米棒表现出卓越的电化学特性,包括在 0.1 A g-1 条件下具有 564 mA h g-1 的高比容量和出色的循环寿命,在 5 A g-1 条件下循环 5000 次后仍能保持 164.2 mA h g-1。此外,在电解液中加入 Na+ 能有效缓解 Na+ 的剥离以及 NVO 中 Zn 树枝状分子的沉积,从而进一步提高了循环稳定性。本研究的发现为快速高效地合成高质量的 ZIB 阴极材料提供了一种可行的方法。
Efficient Preparation of Metal-Ion Intercalated Vanadium-Based Cathodes for High-Performance Aqueous Zinc-Ion Batteries: Na2V6O16·3H2O as an Example
The inherent challenges associated with aqueous zinc ion batteries (AZIBs), such as low energy density and slow diffusion kinetics, pose significant obstacles to their widespread adoption as energy storage systems. These limitations mainly stem from the nongreen and complex preparation process of high-quality cathode materials. In this study, we propose an approach utilizing microwave-assisted ball milling to expedite the fabrication of vanadium-based intercalated nanomaterials, aiming at solving the problem of prolonged reaction at high temperatures, which is unavoidable in the preparation of anode materials. Na2V6O16 (NVO) nanorods were synthesized in just 40 min under aqueous solvent conditions. These nanorods exhibit remarkable electrochemical properties, including a high specific capacity of 564 mA h g–1 at 0.1 A g–1 and an excellent cycle life, maintaining 164.2 mA h g–1 after 5000 cycles at 5 A g–1. Additionally, the incorporation of Na+ into the electrolyte effectively mitigates the stripping of Na+ and the deposition of Zn dendrimers from NVO, further contributing to enhanced cycling stability. The findings of this study offer a promising approach to the rapid and efficient synthesis of high-quality ZIB cathode materials.
