"Probing a battery electrolyte drop with ambient pressure photoelectron spectroscopy”

Operando ambient pressure photoelectron spectroscopy in realistic battery environments is a key development towards probing the functionality of the electrode/electrolyte interface in lithium-ion batteries that is not possible with conventional photoelectron spectroscopy. Here, we present the ambient pressure photoelectron spectroscopy characterization of a model electrolyte based on 1M bis(trifluoromethane)sulfonimide lithium salt in propylene carbonate. Our article provides insights into the liquid components of a lithium ion battery and the necessity to stabilize the liquid phases in ambient pressure photoelectron spectroscopy measurements.
