Fig. 5: Operando XRD of the Ag|LLZO|Li cell.

a Operando XRD patterns and pattern image acquired at 2θ of 10–60° at 30 min/spectra during the first three cycles. Inset shows the charge/discharge profile. b Operando XRD pattern image obtained at 2θ of 36–42°° at 5 min/spectra during one cycle. c Intensity profiles of the indexed phase of the Li-Ag alloy with the charge/discharge profile.
