Figure 4. (A-C) CCD curves of Li/SPE-blank/Li, Li/CSPE-15 dry-LLZO/Li, and Li/CSPE-15 wet-LLZO/Li batteries at 60 °C, (D and E) EIS spectra and voltage-time curves at 0.1 mA cm^-2 before long cycling for the same batteries; and (insert) magnified view of local voltage distribution. CCD: Critical current density; EIS: electrochemical impedance spectroscopy; SPE: solid polymer electrolyte; LLZO: Li_6.4Ga_0.2La₃Zr₂O₁₂.
