Batteries are the key technology for the success of electro mobility. Currently, the focus is on classic liquid electrolyte systems and on further development with regard to their energy density, fast charging capacity, safety and costs. In addition, other storage systems, such as the solid-state battery, are moving into the focus of research due to their outstanding properties, such as improved operation safety, the advantages in terms of volumetric and gravimetric energy density and the potential use of metallic anode material e.g. lithium.
The focus of the project is to increase the power density of all-solid-state cells by micro-structured solid electrolyte cathode and the use of a Li metal anode with a passivation layer. For this purpose, additive and subtractive processes for the targeted structuring of the solid electrolyte cathodes from polymers and ceramics are developed. The main topics here are the development and investigation of specifically structured composite materials and the interaction between material and process technology.
The ifs aims to sinter selectively oxide solid electrolytes using laser radiation. Suitable laser beam sources are identified and efficient operating windows defined by varying the process parameters. In addition, binder modification and the interaction on the laser structuring is examined.
