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.
