In this paper, a high-performance anode material is successfully prepared using a liquid-phase coating method, with special spinnable pitch as the external carbon source and regenerated graphite as the core. The results show that after high-temperature treatment, the Semi-Crystalline nanocarbon layer generated from the spinnable pitch effectively covers the surface of the regenerated graphite matrix and fills the surface pores and defects in the graphite material, forming a unique “core–shell” structure composite.
