Recent years have seen monumental and exciting developments in the field of all-solid-state batteries (ASSBs). I will talk about several exciting scientific breakthroughs that have led to a renaissance of solid state chemistry. Despite its promises, solid state batteries still face a multitude of technical hurdles before commercialization can be achieved. Amongst these challenges, none are more daunting than the ability for scale-up prototyping, specifically, enabling technology transition from the laboratory to the pilot scale. A vast majority of ASSB reports to date are still limited to form factors impractical for actual device operation. In this plenary talk, I will provide a perspective on a wide range of scalability challenges and considerations for ASSBs, including solid electrolyte design and synthesis, dry electrode processing, cell assembly for optimum interfacial control, and stack pressure considerations at the cell level. More importantly, I will discuss ways to bridge the development gap between fundamental research and applications, through partnerships and collaborations between the industry, univeristies and national laboratories.
Most of the solid state battery work presented is funded by the LG Energy Solution through the Frontier Research Laboratory (FRL) program. The part regarding the advanced characterization tool development is funded by the Office of Science, US Department of Energy.
