| Abstract: |
| In the field of lithium-ion battery materials, much attention is paid to mineral materials with unique structures. Stibnite is an important mineral material, whose main component is Sb2S3 and has the characteristics of two-dimensional layered structure, high grade and easy mining. Natural graphite is widely distributed in the world, which has the advantages of high electrical conductivity and affordable price, and can be used as a matrix material with excellent electrical conductivity. In this study, natural minerals such as stibnite and graphite were used to prepare Sb2S3/BG composite materials with different proportions. The experimental results show that the stability of Sb2S3/BG composite is improved after the addition of BG (Ball-milling modified graphite) material, and high reversibility is maintained in the long cycle. Among them, Sb2S3/BG (1:1) composite still maintains 351 mAh g-1 discharge specific capacity after 110 cycles at 1C current density, and the capacity retention rate reaches 52%. |
