Figure 10. (A) Schematic representation of S-CDs/rGO preparation via the annealing of GO and BDS in a tube furnace. (B) Schematic illustration of the LIB full cell with LiFePO₄ as the cathode and S-CDs/rGO-900 as the anode. (A and B) Reprinted with permission from Ref.^[121]. Copyright © 2021 John Wiley & Sons. (C) Schematic illustration of the fabrication process of pure Bi₂Se₃ and Bi₂Se₃/CDs composites, along with a mechanism analysis of lithium storage in the Bi₂Se₃/CDs-200 electrode. (D and E) In situ X-ray diffraction (XRD) patterns with corresponding galvanostatic charge-discharge (GCD) curves, and (F) atomic model illustrating the phase change of the Bi₂Se₃/CDs-200 electrode during the initial cycle. Nyquist plots of Bi₂Se₃/CDs-200 at different voltage points during the third discharge (G) and charge (H) processes. (C-H) Reprinted with permission from Ref.^[122]. Copyright © 2022 Elsevier.
