In late March 2026, the Federal Ministry of Research, Technology, and Space launched Germany’s largest consortium dedicated to sodium-ion battery technology, named SIB:DE Entwicklung. Bringing together 25 partners from academia and industry, the initiative aims to develop a sustainable, safe and cost-effective alternative to conventional lithium-ion batteries. Focus areas include the production of large-format, market-ready cells, optimization of recycling processes and rapid industrial implementation of research findings.
As Europe accelerates its mobility transition and integrates growing volumes of renewable power into the grid, reliable energy storage solutions are essential for both electric vehicles and stationary applications such as 5G telecommunications infrastructure. While lithium-ion batteries remain dominant, their reliance on limited materials like lithium, cobalt and nickel poses supply and geopolitical challenges. Sodium, by comparison, is abundant, low-cost and widely available, offering a promising route to a more resilient European energy supply.
SIB:DE Entwicklung will assess sodium-ion technology’s applicability across mobile and stationary systems and establish a complete manufacturing ecosystem in Germany and Europe. Coordinated by EDAG Production Solutions GmbH & Co. KG, the consortium comprises eleven industrial firms and fourteen research organizations, with support from eleven associated partners. Key contributors include the Fraunhofer Institutes for Manufacturing Technology and Applied Materials Research (IFAM), Battery Cell Production (FFB) and Ceramic Technologies and Systems (IKTS), alongside the Karlsruhe Institute of Technology and Technical University of Munich. Industry collaborators include Coperion, Jungheinrich and VARTA Storage.
Over a three-year funding period through February 2029, Projektträger Jülich will manage the 14.5 million euro grant provided by the Federal Ministry. By leveraging combined expertise from science and industry, the project aims to fast-track the scaling and market penetration of sodium-ion cells, strengthen Europe’s technological sovereignty and support a competitive, sustainable battery value chain.
