Operando studies of solid electrolyte interphase (SEI) formation with the electrochemical-Surface Force Balance (e-SFB)

Puntos clave

• 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
