摘要: 本研究系统探究硫化镍复合材料作为钠离子电池(SIBs)负极材料的电化学性能。针对硫化镍材料在实际应用中存在的体积膨胀和循环稳定性差等问题,通过高能球磨法处理硫化镍颗粒并实施碳包覆,成功制备了碳包覆硫化镍(Ni3S2/BM/C)复合材料。结果表明,Ni3S2/BM/C复合材料在200 mA·g-1电流密度下循环100次后,可逆容量达到378.7 mAh·g-1,显著优于Ni3S2可逆容量(163.4 mAh·g-1)。Ni3S2/BM/C复合材料优异的电化学性能源于其独特的结构优势,纳米级颗粒尺寸能够有效缓解充放电体积膨胀,均匀碳包覆层可以提高电导率且对长循环稳定性至关重要。本研究不仅为硫化镍复合材料在钠离子电池中的应用提供了新思路,也为高性能钠离子电池负极材料的开发提供了参考。

Abstract: The electrochemical performance of nickel sulfide composite materials were systematically investigated as anode materials for sodium-ion batteries (SIBs). To address the challenges of volume expansion and poor cycle stability in nickel sulfide materials in practial applications, nickel sulfide particles were treated by high energy ball mill method, and carbon-coated nickel sulfide (Ni3S2/BM/C) composites were prepared. Ni3S2/BM/C composite materials exhibit reversible capacity of 378.7 mAh·g-1 after 100 cycles at a current density of 200 mA·g-1. This performance is significantly higher than that of commercial Ni3S2 (163.4 mAh·g-1). The excellent electrochemical performance of Ni3S2/BM/C composite materials originate from their unique structural advantages: the nanoscale particle size effectively alleviates volume expansion during charge/discharge cycles, while the uniform carbon-coating enhances electrical conductivity and plays a crucial role in long-term cycling stability. This study not only presents a promising strategy for the implementing of nickel sulfide composites in SIBs, but also provides reference for developing advanced SIBs negative electrode materials.
