Use of solid-state batteries

The potential of solid-state technology compared to today's state-of-the-art battery cells is a key driver for research into this field. Increased energy density and greater operational reliability of solid-state cells make the technology particularly attractive for mobile applications. Among other things, this enables longer ranges and reduced vehicle weights to be achieved. Solid-state batteries are therefore considered a promising key technology for fully electric mobility. At Fraunhofer ZESS, the focus is on the development, manufacture, and testing of solid-state cells, particularly for mobile applications. To ensure optimal cell design for specific applications, early evaluation of potential cell properties during the battery usage phase is essential. Apart from a wide range of production-related issues, challenges still exist in areas such as material stability. The aim of the work at Fraunhofer ZESS is therefore to achieve competitive cycle stability for the cells, as a long service life is an essential criterion for the commercial viability of the technology.
