GNBatt - Gradient materials for sustainable battery technologies

Lithium-ion and sodium-ion batteries are essential for electromobility and the energy transition, with the cathode playing a decisive role in determining performance and costs. High-energy cathode materials are subject to cyclic structural changes that cause mechanical stresses and limit their service life. Gradient materials reduce these stresses, increase longevity, and are therefore of great interest to industry. The GNBatt project is developing scalable manufacturing processes for such materials in the new ZSW synthesis facility “Powder-up!”. The NMI Reutlingen is supporting the development with high-resolution analyses to understand microstructure and lateral composition.
