Materials for all solid-state lithium-ion batteries — •Susann Nowak¹, Frank Berkemeier² und Guido Schmitz¹ — ¹Institut für Materialwissenschaften, Heisenbergstr. 3, 70569 Stuttgart — ²Institut für Materialphysik, Wilhelm-Klemm-Str. 10, 48149 Münster

All solid-state batteries present a very interesting model system for studies on kinetics and thermodynamics in lithium-ion batteries, but are particularly demanding in the specifications needed for the utilization of materials as their components, for example they have to show a very low surface roughness. In the current poster we present the fabrication and characterization of different materials, which can be used in an all solid-state batteries. The properties of lithium iron phosphate, lithium phosphorous oxynitride and tin are shown. Fabrication is carried out by ion beam sputtering and in the case of lithium iron phosphate post annealing under argon atmosphere. Characterization is carried out via electrochemical methods (chrono potentiometry and cyclic voltammetry), charge state depending x-ray diffraction (XRD), and transmission electron microscopy (TEM). An outlook on measurements on a complete all solid-state system is given.
