High-performance, long-lasting energy storage devices are crucially important for many future-oriented technologies: e.g. for electromobility, for mobile end devices such as tablets and smartphones as well as for the efficient use of energy from renewable sources. Dr. Daniel Mutter from the Freiburg-based Fraunhofer Institute for Mechanics of Materials (IWM) was able to clarify what the chemical composition of solid ceramic electrolytes should be in order to ensure good performance in lithium-ion batteries. The research was published in the Journal of Applied Physics (https://doi.org/10.1063/1.5091969). Such solid electrolytes are more environmentally friendly than traditional liquid electrolytes and could make lithium-ion batteries significantly safer and more efficient.more info
