Although the formation of Li dendrites in the LLZO solid-state electrolyte is the central issue in this field, there is surprisingly no agreement on the electrochemical protocol required to determine the critical current density (CCD), that is the current density at which Li dendrite propagation begins 9, 10.
However, achieving the key U.S. DOE milestone of a power density of 33 kW L –1 appears to be a significant hurdle in current ASSLBs. One of the main reasons is that advancements in solid electrolyte (SE) conductivity have been prioritized over the critical current density (CCD) when employing an elemental Li anode.
The relationship between fabrication pressure applied duration and critical current density in symmetric cell were revealed. A constant pressure setup mitigates the volume change during cycling, and effectively increase the critical current density of the full cell.
