Abstract
Solid-state batteries are widely recognised as a key enabler for the next generation of high-performance, safe, and sustainable energy storage systems. Yet, moving from laboratory concepts to industrial-scale manufacturing remains one of the most critical challenges. This article explores how the HyLiST project addresses this gap by defining the boundary conditions for producing solid-state battery cells at a scale of up to 1 GWh per year. By comparing laboratory-scale processes with large-scale manufacturing concepts, the article highlights the technical constraints, scalability challenges, and critical process parameters that shape industrial feasibility. From electrode fabrication and solid electrolyte processing to stacking, sealing, and formation, the analysis provides a clear picture of what it takes to translate advanced materials into manufacturable battery cells. Written to engage both technical and non-technical audiences, this blog illustrates how HyLiST is laying the groundwork for reliable, scalable, and competitive solid-state battery production in Europe.
