A landmark for the UK battery sector has been achieved with the unveiling of a cylindrical sodium-ion cell manufactured using Welsh materials and innovation.
Batri, in collaboration with Swansea University, has produced an 18650-format demonstration cell believed to be the first of its kind made in the UK with fully UK-manufactured anode and cathode materials.
Supported by Faraday Institution Sprint funding, the project demonstrates the rapid acceleration of Britain’s sodium-ion capabilities and signals the emergence of a sovereign supply chain. The cell incorporates sodium-ion chemistries developed jointly by Batri and Swansea University, including composite carbon derived from Welsh coal, with active materials representing home-grown intellectual property and nationally available supply routes.
Dr Stephen Hughes, CTO of Batri, said, “This achievement shows what is possible when UK science, UK manufacturing, and bold ambition come together. We’re unlocking a sodium-ion ecosystem that starts in Wales and is aiming to reach global markets.”
The breakthrough marks the start of a wider programme, with Batri scaling up both material manufacture and in-house cell-building in Wales. Strategic partnerships, including with AceOn Group, will see UK-made sodium-ion cells integrated into swappable packs and custom energy systems for demanding environments.
Professor Serena Margadonna highlighted Swansea’s growing role as a sodium-ion hub, while Cllr Rob Stewart noted the milestone’s impact on regional investment and skilled job creation.
As Dr Hughes added, “Producing a cylindrical sodium-ion cell using UK-made anode and cathode materials is not just a scientific milestone, it is a strategic one.”
