%X The combination of solid ceramic-like electrolytes with inorganic electrodes, thus creating an all solid-state battery, requires a sophisticated co-processing, taking into account different chemical and thermal stability of the applied materials. Thin-film batteries allow – on the one hand – a detailed analysis of the compatibility of active storage material and the electrolyte because of well-defined interfaces. On the other hand, thin-film batteries also have the potential for energy storage solutions in applications with short-term or low power consumption. Optionally, a stacking of active thin layers can increase the energy content.  In general, the deposition of a functional layer for solid-state battery cells requires a heat incidence that can lead to an undesired and detrimental diffusion of constituents into the substrate or into adjacent layers, to mechanical stresses and resulting cracks due to different coefficients of thermal expansion, or even to a decomposition of parts of the battery. This work presents how different materials (for instance Lithium-oxynitride (LiPON)  based or Lithium-Lanthanum-Zirconium-oxide (LLZ) based electrolyte materials) and different thin-film deposition processes (for example physical vapor deposition, spin-coating, dip-coating, ink-jet-printing) have impact on the microstructure, the inter diffusion and, as a result, on the performance of the cells. Analysis was done, among others, by high-resolution scanning electron microscopy, secondary ion mass spectrometry, optical emission spectroscopy, nuclear reaction analysis, Rutherford backscattering, electrochemical impedance spectroscopy, galvanostatic charge-discharge measurements and cyclic voltammetry.As an outlook, the economic feasibility of thin-film deposition technologies like physical vapor deposition is discussed.
