Extended Data Fig. 1: Digital images (top row) and the zoomed-in images (bottom row) of the Al° electrode after the chronoamperometry measurements in various liquid electrolytes at 60 °C.
From: Stable non-corrosive sulfonimide salt for 4-V-class lithium metal batteries

The pitting corrosion of the Al° are marked by small purple arrows in the LiTFSI-based electrolyte.
