The aim of the consortium of 15 working groups from 13 companies and universities is to develop a cost-effective cell chemistry for sodium-ion batteries, which will then be converted into cell formats that can be used industrially. The Federal Ministry of Research is providing 7.5 million euros in funding.

The research project “ENTISE” has officially started. The abbreviation stands for development of sodium-ion technology for industrially scalable energy storage. A total of 13 companies and universities are involved in the project, which Varta initiated and coordinates. 15 working groups are now working on the development of a high-performance and environmentally friendly cell chemistry for sodium-ion batteries, which will then be converted into industrially usable cell formats.
The focus of the “ENTISE” research project is the further development of existing material concepts and processes. In terms of technology, the storage capacity of the cathode and anode in particular is to be improved, as Varta announced on Tuesday. To do this, the materials used, including the electrolytes used, must be optimized. Another important aspect is cycle stability, which is to be improved through the development and use of new materials, optimized electrode materials and coatings. At the end of the process, a prototype in a round cell design is to be created.
The Federal Ministry of Research is funding “ENTISE” with 7.5 million euros. The project is scheduled to run for three years and officially ends at the end of May 2027. In addition to Varta, the project partners are the Karlsruhe Institute of Technology, Helmholtz Institute Ulm; the Humboldt University of Berlin; the University of Freiburg; the Center for Solar Energy and Hydrogen Research Baden-Württemberg; the Justus Liebig University of Giessen; the Jülich Research Center; Eura AG; E-Lyte Innovations GmbH; IBU-tec advanced materials AG. In addition, an unnamed cell manufacturer with a connection to the automotive industry is also involved in the project, as Varta explained.
