Fig. 3. Characterization of the SN-based electrolyte. (a) Structural formula of SN, PVDF-HFP, and NaClO4. (b) SEM image and optical photograph (inset), and (c) TEM image and corresponding elemental maps (C, N, F, Na, Cl, and O) of the SN-based SSE. (d) IR spectra and (e) XRD patterns of SN, PVDF-HFP, NaClO4, and the SN-based SSE. (f) Ionic conductivity and Young's modulus of the SSE with different contents of PVDF-HFP. (g) Ionic conductivity of the optimal SSE at different temperatures (10, 20, 30, 40, 50, and 60 °C).
