摘要
Abstract In this paper, tin-carbon composites were prepared by the hot carbon reduction method and used as anode materials for lithium-ion batteries. The results show that the hot carbon reduction method can effectively reduce SnO2 to spherical metallic tin, and the excess of carbon affects the size and shape of tin spherical particles. The higher the tin content is, the higher the lithium intercalation potential of the anode material is. The improvement of cyclic stability of tin-carbon composites is at the expense of reversible capacity. The core-shell structure of pitch pyrolysis carbon can effectively inhibit the reversible capacity decay caused by tin volume expansion.
