Differences in the Interfacial Mechanical Properties of Thiophosphate and Argyrodite Solid Electrolytes and Their Composites
Interfacial
mechanics are a significant contributor to the performance
and degradation of solid-state batteries. Spatially resolved measurements
of interfacial properties are extremely important to effectively model
and understand the electrochemical behavior. Herein, we report the
interfacial properties of thiophosphate (Li3PS4)- and argyrodite (Li6PS5Cl)-type solid electrolytes.
Using atomic force microscopy, we showcase the differences in the
surface morphology as well as adhesion of these materials. We also
investigate solvent-less processing of hybrid electrolytes using UV-assisted
curing. Physical, chemical, and structural characterizations of the
materials highlight the differences in the surface morphology, chemical
makeup, and distribution of the inorganic phases between the argyrodite
and thiophosphate solid electrolytes
