The two-year postdoctoral project: Scalable Production of Solid-State Batteries through Precision Manufacturing will be conducted at the Department of Production Development ITM. The project offers an opportunity to conduct interdisciplinary research at the intersection of precision manufacturing and metrology, production technology and digital manufacturing, applied to solid-state batteries. The aim is to investigate how high manufacturing precision can reduce process variations, minimize process-induced defects and increase robustness of the manufacturing process, and how variations arise and propagate throughout the entire manufacturing chain, from production equipment performance and component machining to cell assembly, and how these can be characterized, quantified and controlled. A central goal is to develop measurement-based methods that describe the relationship between manufacturing precision, process capability and product quality. Precision metrology and integrated quality control will be used to identify critical process parameters, analyze error sources and establish manufacturing tolerances that enable robust production. Advanced measurement and non-destructive testing methods, including optical and laser-based measurement techniques, industrial X-ray computed tomography (CT) and ultrasonic testing, will be used to monitor process stability and identify defects at various stages of the manufacturing process. The collected measurement data can be combined with process models and digital engineering tools to support tolerance analysis, process analysis and continuous improvement. The expected outcomes of the project are new methods to reduce manufacturing variations, improve process capability and enable reliable industrial scale-up of solid-state battery production.
