%X Batteries belong to the most efficient storage media for electrical energy. Among the battery types commonly used today, lithium batteries have the highest energy density with regard to weight as well as with regard to volume. Up to now, they are mainly used for small-scale applications like cell phones, but future use may also include lithium batteries in electric cars or for large-scale storage of renewable wind and solar energy. 
%X Major problems arise from the liquid organic electrolyte of today’s lithium batteries, which is corrosive, sensitive to air and water, and particularly highly flammable.  A scale-up of the battery size also amplifies the risk of accidental over-heating and subsequent explosion.
%X Solid-state batteries circumvent the problems of organic electrolytes by using inorganic lithium ion conductors as electrolytes. In the oxide class of lithium ion conductive materials Li7La3Zr2O12 (LLZ) has the highest reported Li ion conductivity. Especially their inherent safety, easy handling and compatibility with metallic Lithium make them most promising candidates for solid-state batteries. Since LLZ exhibits considerably lower ion conductivity than liquid electrolytes, a thin-film electrolyte approach was chosen to reduce the overall ohmic resistance of the electrolyte. 
%X Focal points of this work are manufacturing of solid-state batteries by means of thin-film technologies that are qualified for large-scale production, analysis of the composition and phases of the electrochemically active layers of the battery, and electrochemical performance analyses of the materials used.
