Key Points

The research aims to observe the formation of the solid electrolyte interphase (SEI) at electrode surfaces directly.
Utilized the electrochemical-surface force balance (e-SFB) technique
Conducted proof-of-concept measurements
Focused on lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) interactions
Successfully demonstrated direct observation of SEI formation
Identified key behaviors at the electrode that contribute to SEI development

Implication

Operando studies demonstrate SEI formation at electrode surfaces using e-SFB, highlighting its utility.

Abstract

This study demonstrates the utility of the electrochemical-surface force balance (e-SFB) for observing solid electrolyte interphase (SEI) formation directly at an electrode surface. Through proof-of-concept measurements of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI)...
