    In the umbrella concept “Research Fab Battery”, German scientists want to develop novel batteries that are capable of storing at least 70 percent more energy for electric vehicles and smartphones than conventional lithium-ion solutions while maintaining the same volume. As part of the cluster of competence for battery materials “ExcellBattMat“ funded by the Federal Ministry of Education and Research (BMBF), Dresden's “ExcellBattMat Center” (project KaSiLi: structural cathode adaptation for silicon and lithium materials) contributes key components for this new battery generation. On November 1, 2019, researchers from Fraunhofer, TU Dresden and Leibniz started working together on innovative battery electrodes consisting of ultra-thin silicon or lithium layers to achieve high energy densities.
