Fig. 1: Morphology and composition comparison between extruded and evaporated lithium.
From: High performance ultra-thin lithium metal anode enabled by vacuum thermal evaporation
Pictures of the punched anodes and top view SEM images of the evaporated (a) and extruded (b) Li metal anodes. Cross sectional SEM images of evaporated (c) and extruded (d) Li metal. EDX depth profiles of the atomic concentration of Li, O and C as a function of the accelerating voltage for samples of extruded and evaporated Li metal foils and calculated (Casino) average generation depth of detected Li Kα emission in Li metal for the applied voltages (e).
