Roadmap on Li-ion battery manufacturing research

Abstract Growth in the Li-ion battery market continues to accelerate, driven primarily by increasing need for economic energy storage electric vehicles. Electrode manufacture slurry casting is first main step cell production but much of manufacturing optimisation based on trial and error, know-how individual expertise. Advancing science that underpins electrode critical adding value chain. Overcoming current barriers requires advances materials, technology, in-line process metrology data analytics, can enable improvements performance, quality, safety sustainability. In this roadmap we explore research opportunities improve each stage process, from materials synthesis through calendering. We highlight role new such as dry processing, advanced design supported level, physics-based modelling. Progress models processes also considered. conclude there a growing innovations aid fundamental understanding feedback control, an opportunity reduce urgent imperative sustainability manufacture.
