Europe’s first sodium-ion cell made with fully domestic components

Welsh battery breakthrough uses UK-manufactured anode and cathode materials as well as active materials available through local supply chains. Batri plans to scale up material manufacturing and cell building capability.

From ESS News

A research team from Batri and Swansea University have built a new cylindrical sodium-ion cell using UK-sourced materials, believed to be the first of its kind.

The 18650-format sodium-ion cell combines chemistries developed by UK-based energy storage company Batri and Swansea University, including Welsh coal-derived composite carbon.

Made using fully UK-manufactured anode and cathode materials, the 18650 cell was hailed as a “strategic milestone” by Stephen Hughes, chief technical officer at Batri, who said it “proves that sovereign battery production is viable and already happening here in Wales.”

No way are they competing against Catl who are now fully manufacturing a sodium battery at 50% less cost of lithium ion and are capable of of over 3 million mile lifespan
