Solid-state batteries

Various research institutes and companies are working on the development of solid-state batteries, including the PSI in W├╝renlingen. This involves drying electrodes. The liquid electrolyte in the previous Li-ion battery applications is fire-hazardous and therefore there are strict and cumbersome transport regulations. In the planned ceramic solid-state batteries, both the cathodes and the electrolyte are made of oxidic or sulphide materials. These batteries thus not only do without liquid components, but also without polymer components. Companies develop scalable manufacturing solutions for the drying and sintering of oxidic composite cathodes and solid electrolyseparators. However, it will take some time before this technology can be delivered in large quantities.
