Voltage versus time curves for Li-symmetrical cells and shematics of lithium deposition on FGI@Li. (a) A comparison of the electrochemical stability of the FGI@Li (blue) and non-protected Li (red) with excess of the ether based electrolyte (27 μL cm−2) at a current density of 0.5 mA cm−2. (b) Enlarged ranges from 70 h to 82 h, 222 h to 234 h, and 414 h to 426 h. (c) Schematic illustration of Li-ion penetration through the FGI and lithium deposition onto lithium surface underneath the FGI.
