Figure 3. Lithium deposition behavior of different anodes. Lithium deposition morphology at 1 mA cm^-2 for (A) 1 h and (B) 3 h for the composite anode, (C) 1 h and (D) 3 h for pure Li metal anode; surface potential mappings of (E) the composite anode and (F) pure Li metal anode through Kelvin probe force microscopy (KPFM) and corresponding (G and H) statistical distribution; (I) schematic illustration of Li deposition process on these two anodes.
