As promising electrode materials for aluminum-ion batteries (AIBs), transition metal sulfides have attracted significant attention. However, the relative low energy density and poor rate property restrict their further applications. Herein, channels-rich VS₄ nanowire clusters were synthesized via an amine ions-assisted method. When assessed as a cathode for rechargeable AIB, the VS₄ nanowire clusters exhibit superior electrochemical performances, specifically, outstanding rate property (103.32 mAh g^-1 at 800 mA g^-1), good cycling stability and a high reversible capacity of 252.51 mAh g^-1 (at 100 mA g^-1). Moreover, ex-situ X-ray diffraction (XRD) and in-situ Raman techniques reveal that the as-prepared VS₄ nanowire clusters have stable channels-rich structures, which is favorable for the mass transfer in electrochemical reaction. A mechanism of intercalation is proposed for the electrochemical process. This work takes a step toward the development of high-performance electrode materials for AIBs and provides new insights into the chemistry of AIBs for electrochemical energy storage.

作为铝离子电池（AIB）的有前途的电极材料，过渡金属硫化物已引起广泛关注。但是，相对较低的能量密度和较差的速率特性限制了它们的进一步应用。在此，通过胺离子辅助方法合成了富通道的VS ₄纳米线簇。当用作可充电AIB阴极评估中，VS ₄纳米线束表现出优良的电化学性能，具体而言，突出的速率特性（103.32毫安克^-1以800mA克^-1），良好的循环稳定性和252.51毫安g的高可逆容量^-1（在100 mA g ^-1时）。此外，异位X射线衍射（XRD）和原位拉曼技术表明，所制备的VS ₄纳米线团簇具有稳定的富通道结构，这有利于电化学反应中的传质。提出了一种用于电化学过程的插层机理。这项工作朝着用于AI​​B的高性能电极材料的发展迈出了一步，并为用于电化学能量存储的AIB的化学方法提供了新的见解。
