Our open-access perspective paper on the challenges of scaling battery manufacturing was just published in Nature Communications! In this paper, we discuss why battery quality is important, why it’s hard to achieve in battery manufacturing, and how advanced inspection — specifically CT — can help.

I started working on this paper shortly after starting Glimpse in early 2023. Two years later, I have to admit the final result already feels slightly dated (specifically, the highly optimistic introductory paragraph). In the past two years, Western battery manufacturing ambitions have faced some major setbacks, headlined by Northvolt’s bankruptcy. Now, everyone in the industry recognizes that battery manufacturing is hard. Nevertheless, I hope this paper can help the community by highlighting the challenges of quality control in battery manufacturing and the role of advanced inspection in achieving it.
