Abstract:
Using a simple hydrothermal method, we developed a Si@SnS anode material with SnS nanoparticles uni-formly attached to the surface of silicon nanoparticles. Utilizing the first charge-discharge reaction mech-anism of SnS, combined with the artificial solid electrolyte interphase to improve the solid electrolyte interphase stability of silicon-based materials and the introduction of conductive additives to improve the conductive properties of silicon-based materials, the Si@SnS material exhibits very excellent perfor-mance when applied to lithium-ion battery anodes. At a current density of 0.5A.g-1,after two cycles, the overall resistance of the Si@SnS material battery is reduced by nearly 55% relative to the resistance of the pure silicon battery. As a half-cell anode material, the first coulombic efficiency of Si@SnS at a current density of 1A.g -1 reached 85%, and after 200 cycles, it provided a reversible capacity of 1790 mAh.g -1 and a capacity retention rate of 74.6%.
