Scaling up new battery technologies from the lab to mass production remains a significant challenge. AI-driven digital twins are being explored as powerful tools which enabling predictive modeling, process optimization, and real-time decision-making – while also enabling exciting new possibilities, such as AI-driven co-learning and co-optimization opportunities in battery manufacturing. As the leading foundational partner of the new Battery Cell R&D Center (BRDC), Honda is actively engaged in developing these technologies to accelerate advancements of in-house battery production. This talk will present insights from a joint Honda-OSU investigation into process modeling, identifying key barriers to scale-up and demonstrating how digital twins may overcome them. We will explore current progress, ongoing challenges, and the future outlook for these tools towards the next-generation of battery manufacturing.
