The Ferrum facility, housed in one of Sandvik Materials Technology’s factories, will be Swedish startup Altris’s first industrial manufacturing facility. Sodium-ion cathode gigafactory from Northvolt-backed Altris

Natron is grateful for the continued support from ARPA-E and Clarios which has helped make this project possible,” said Colin Wessells, Natron’s founder and CEO. “This project marks the beginning of a new era for Natron, in which we move from product development to serving our customers at a massive scale. Its batteries are primarily used for critical power applications like data centres and telecoms networks but the company hopes future applications include EVs and grid-scale energy storage. The company has been working on its sodium-ion battery chemistry for mass production for a decade and was the first to achieve a UL 9540A fire testing certification for the battery chemistry. Prussian blue electrode sodium-ion chemistry will be manufactured in the Michigan plant. Under the agreement with Clarios, electrodes and large format cells based on Natron’s proprietary ‘Largest sodium-ion battery production facility in the world’Ĭalifornia-based Natron Energy claimed the facility, which will use a portion of the Meadowbrook site, will be the largest sodium-ion battery plant in the world. Ferrum will produce 2000 metric tonnes of Altris’ cathode material, Fennac, each year, enabling 1GWh of sodium-ion battery production. In the same week, Swedish sodium-based cathode material startup Altris said it signed a deal with Sandvik Materials Technology to house its first industrial scale manufacturing facility in Sandviken, called ‘Ferrum’. It will produce 600MW a year of Natron’s batteries when mass production begins in 2023. Sodium-ion battery producer Natron Energy has announced a strategic partnership with battery producer Clarios International to develop the production facility at Clarios’ exiting lithium-ion Meadowbrook facility in Michigan.

New sodium-ion battery production facilities have been announced in the US and Sweden by Natron Energy and Altris, respectively, with both set to start production in 2023. The Clarios Meadowbrook facility in Michigan will produce up to 600MW a year of Natron’s batteries.
