In this Battery2030+ Excellence Seminar, Dr. Simon Clark discusses role of semantic technology in accelerating battery research and innovation. He begins by highlighting the need for structured data in battery R&I. Then, he reviews existing semantic technology solutions from other domains and the challenges of extending them to materials science. Next, he shows some examples of how to bring battery data into the Semantic Web and what kinds of opportunities it opens. Finally, he closes with a look to the future.
