Abstract:

In recent years, the surge in research investment within the battery field has presented researchers with challenges of information overload and knowledge gaps. This study examines the Retrieval-Augmented Generation (RAG) architecture of large language models in the battery domain, offering a review of contemporary research and future prospects. We describe the working principles of the RAG architecture, affirm its reliability in specialized domains, and discuss its applications across three key areas as follows: battery material design, battery cell design and manufacturing, and battery management systems for e-mobility and electric grids. In the section on battery material design, the study highlights the hallucination-free generation capabilities of RAG in data extraction, research protocol design, and multimodal data querying. The section on battery cell design and manufacturing elucidates RAG's role in enhancing research-driven battery cell design and bridging the gap between industry and academia, thereby aiding industrial control processes. The discussion on battery management systems for e-mobility and electric grids underscores RAG's contribution to cross-domain knowledge integration and system-level operation and maintenance support. The study concludes by considering the application of multimodal RAG technology in battery research and anticipates further expansion of RAG applications in this field.
