a XRD spectrum of Li electrode treated with 1, 3, and 5 wt% SnF2. b–e Photographic images of Li with different weight percentage concentrations of SnF2. f–i The corresponding top-view SEM images from b to e. The scale bars are 20 μm. j–m The corresponding cross-sectional SEM images from f to i. The scale bars are 100 μm.
