AFM characterization of morphology of polished MA surfaces. a–d AFM images of Li surface before (a) and after stripping (b) and plating (c, d) in the electrolyte of 1 M LiTFSI/DME-DOL. e, f AFM images of Na surface after polishing in the electrolyte of 1 M NaOTf/diglyme. g, h AFM images of K surface after polishing in the electrolyte of 1 M KTFSI/DME. Color bars are 0–1 μm (a), 0–300 nm (b, c), 0–1.5 nm (d), 0–150 nm (e), 0–200 nm (g), and 0–1.5 nm (f, h)
