Figure 14. (A) Experimental scheme for preparing Ag‐Li alloy foil. (B) Voltage profiles of Li/Li and Ag‐Li/Ag‐Li symmetric cells at 0.5 mA cm^-2 with a fixed capacity of 1 mAh cm^-2. Reproduced with permission^[156] (Copyright 2021, Wiley-VCH). (C) Schematic illustration of the symmetric coin cell used for CCD detection. (D) Voltage profiles of the symmetric cell using PEO protective layer at step-increased current densities and the cell cycled once under each current density. (E) Voltage profiles of the symmetric cell using PEO protective layer at increased current densities and the cell cycled three times under some particular current densities.
