Title: Three-Dimensional Resistivity vs. Depth Profiling for Advanced Characterization of the Lithium-Ion Battery Solid Electrolyte Interphase

Abstract

In this work, we investigate the evolution of SEI formed from a standard electrolyte (1.2 M LiPF6 in EC:EMC (3:7 wt%)) through various points in cycling on several model Si surfaces. We also examine the solubility of SEI by resting the anode in the cell at varied temperatures then characterizing the residual SEI. Evolution of the SEI surface is also analyzed with atomic force microscopy (AFM) measurements. AFM and SSRM-derived results are presented in combination with chemical characterization, including time-of-flight secondary ion mass spectrometry (TOF-SIMS).
