Abstract in another language
All Solid-State Batteries (ASSBs) with a lithium metal electrode are of high interest for the next generation of lithium ion batteries due to increased capacity and safety. The ceramic garnet solid electrolyte Li7La3Zr2O12 is a promising alternative to currently used liquid electrolytes due to its non-flammable character and wide electrochemical stability window in combination with a high ionic conductivity. Despite the positive aspects of this type of solid electrolyte, an economic mass production of cells is a major challenge. The production of 5-20 μm thick films in combination with high processing temperatures and high dwell times lead to cost-intensive components as well as high process times. Furthermore, co-sintering of the solid electrolyte and cathode active materials >600°C forms isolating interface layers and reduces the performance of the ASSB. In contrast to all other ceramic process technologies, the Powder Aerosol Deposition (PAD) method allows the fabrication of adhering dense ceramic films in the thickness range of several μm at room temperature. In this work, the industrial scalable and moisture free processing of oxide solid electrolyte films for ASSBs via PAD is shown. Furthermore, the electrochemical properties of the films are investigated by temperature dependent impedance spectroscopy as well as cycling experiments.
