Figure 10. Interface of garnet SSE and Li-metal anode. (A) Schematic of the interface between of garnet surface and metallic Li; (B) SEM images of the garnet solid electrolyte/Li-metal interface. Insets are photos of a drop of molten on a garnet disk; (C) EIS profiles of the symmetric Li/garnet cells with and without ALD coating. Inset shows the enlarged impedance curve of the ALD-treated garnet cell; (D) DC cycling of Li/garnet symmetric cells at a current density of 0.1 mA·cm^-2. The inset is the magnified curve of the ALD-garnet cell^[61]. Copyright 2017 Macmillan Publishers Limited.
