Abstract in another language

Significant efforts have been made to develop ASSB by processing ceramic solid electrolyte powder into electrolyte films. Achieving electrolyte films with thicknesses below 20 μm is challenging and currently impedes the commercialization of ASSB. Powder Aerosol Deposition (PAD) is a relatively new technology that can be applied for the production of ceramic films. The advantages of PAD are that very thin films can be easily manufactured and that the process itself requires relatively low temperatures. In PAD, deposition takes place at room temperature and in many cases high sintering temperatures, as required by conventional ceramic processing routes, are not necessary. In first investigations, garnet-type electrolyte PAD films showed promising electrochemical properties. Based on these results, we aim at showing that multilayer films can be produced by PAD and used in ASSB. Our films consist of a composite cathode layer (NMC/LLZO) as well as an electrolyte layer (LLZO). SEM images of the PAD multilayer show that a dense and nanocrystalline film structure is achieved. EDX data confirms that a composite cathode can be created by the simultaneous deposition of the electrolyte and the cathode material. The PAD films exhibit promising electrochemical performance against lithium metal anodes. In the next step we will introduce composition gradients into the cathode layer. It is expected that such gradients will help to improve the kinetics of ASSB and enable increased power and energy densities.
