All Solid State Battery

All-solid-state batteries (ASSBs) present exciting opportunities for pushing the performance and safety of present day Li-ion batteries. A key component in these systems is the Li/Na-ion conducting electrolytes, which have received tremendous attention in the past ten years, leading to numerous breakthroughs in materials discovery with several candidates displaying conductivity on a par with commercial liquid electrolytes. However, understanding of their performance, particularly under realistic operational conditions, is critically lacking. Therefore, our ambition is to quantify the kinetic stability of solid electrolyte systems under practical limits, in respect to the choice of anode, cathode, type and amount of (non)conductive additives in the electrode, temperature, etc., and when possible studying the influence of these parameters in isolation. Such studies are not only crucial for the device level integration of breakthrough solid electrolytes, but they may also shed light on unanticipated and unique phenomena of fundamental importance.
