Abstract: 
Most electrochemical energy storages (battery cells) consist of solid electrodes separated by a liquid electrolyte. If electrode materials are-at least partially-soluble in the electrolyte, detrimental mass transport between both electrodes (electrode cross-talk) occurs. The shuttle mechanism in lithium-sulfur batteries and leaching of Mn in high voltage cathode materials are important examples. Implementing a solid electrolyte (SE) membrane between the electrodes is a comprehensible approach to suppress undesired mass transport but additional resistances arise due to charge transport across the SE and charge transfer through the solid/liquid electrolyte interfaces. The latter contribution is often overlooked as its determination is challenging; however, these interface properties are crucial for practical application. In previous work, a resistive solid/liquid electrolyte interphase "SLEI" has been found at the interface between the SE lithium aluminum germanium phosphate in contact with a liquid ether-based electrolyte. Here, the aim is deeper insight into this interphase formation, referring to a lithium-ion conducting glass ceramic (NASICON-type) and the commonly used thin-film ion conductor lithium phosphorous oxide nitride. The growth of the SLEI is monitored by a combination of electrochemical characterization, X-ray photoelectron spectroscopy, and time-of-flight secondary ion mass spectrometry.
