Fig. 7: In situ EC-AFM characterization of EDL structure under different voltages.
From: Engineering a passivating electric double layer for high performance lithium metal batteries
a Schematic of an in situ EC-AFM cell, which was composed of a HOPG as working electrode, Ag/AgCl as reference electrode, and Pt wire as the counter electrode. The AFM cantilever is inside the liquid. Two-dimensional (2D)-AFM xz count maps HOPG–electrolytes interface at different electrode potential and corresponding Frequency shift versus distance curve in (b) 1 M LiFSI/DME and (c) LiFSI–LiNO3/DME.
