Title: Operando observations of the early stages of Electrode/Electrolyte Interphase formation in Li-ion battery model systems
Affiliation: Uppsala University

Abstract

The Electrode/Electrolyte Interphase is the vital component for successful Li-ion battery operation. Yet after several decades of research, fundamental understanding of the nature and formation mechanism of the Solid Electrolyte Interphase (SEI) remain incomplete. While the anode/electrolyte interphase has been studied intensively over the years, the cathode/electrolyte interphase has received much less attention. Although ex situ measurements were traditionally used to study the Interphase formation, the use of real time operando techniques is today mandatory in order to provide a new insight into these complex processes. We have employed Operando Surface Enhanced Raman Spectroscopy to reveal the processes occurring in the Electrical Double Layer on the gold based model systems relevant to the Li-ion batteries. Preliminary results of both anodic and cathodic electrolyte decomposition processes will be presented in the poster.
