Materials for all solid-state thin-film batteries — •Susann Nowak1, Priyanka Sharma1, Giulio Calcagno1, Matthias Köhler2, Juliane Mürter1, Fabian Wunde2, and Guido Schmitz1 — 1Heisenbergstr. 3, 70569 Stuttgart — 2Wilhelm-Klemm-Str. 10, 48149 Münster
All solid-state batteries received increasing attention over the last years due to the simplified packaging process and increased energy density and safety. The defined thin-film geometry is also well suited to conduct fundamental studies of thermodynamics and kinetics of batteries. Since batteries are complex multilayer devices, it is essential to optimize and characterize anode, cathode and electrolyte materials carefully before combining them in an all solid-state battery. This contribution presents a wide construction-kit of different battery materials which can be successfully produced by ion-beam sputtering. In particular the fabrication and properties of LFP, LMO, LCO, NMC, Sn, Si and LiPON as thin films are shown. Challenges of balancing a full cell and its effects on the energy density of a battery are discussed on a LFP-Sn anode-cathode model. First results on combining battery materials are shown. The behavior of the storage materials can vary drastically due to differing interfacial properties.
