Fig. 7: Lithium plating experiments using different current collectors.

Lithium plating at a current density of 0.15 mA cm−2 of current collectors of Cu, SS and Ni in a CC|LPSCl|Li/CC and b CC/Li|LPSCl|Li/CC cell formats, and c photos of current collectors, LPSCl pellets and lithium metal anode after plating. Note: back side of current collector after LPSCl solid electrolyte contact; one photo of front side shows the surface of current collector after removing the Lithium metal anode; second photo of front side shows together current collector and Lithium metal anode.
