Czech firm Draslovka has formed an R&D partnership with Natron Energy to develop and produce Prussian blue material required for its proprietary sodium-ion battery technologies. The agreement envisages a layered scope of co-operation across Draslovka’s areas of expertise, using its research, production and logistics capabilities on both sides of the Atlantic. 

The company has obtained the necessary permits and will design and build a new reference production facility for the project at its site in Kolin, to be followed by a large-scale facility in 2026 that will help Natron to meet growing demand for sodium-ion batteries, notably in short-term energy storage applications like data centres. 

The former will also serve as a blueprint to expand Draslovka’s operations in the US, where it is also evaluating opportunities for new production plants. Draslovka added that its chemistry “will directly assist in the development of Natron’s supply chain without reliance on critical minerals from high-risk or potentially unstable jurisdictions”.
