Researchers at the Leibniz Institute for Solid State and Materials Research Dresden (IFW Dresden) have developed a new environmentally friendly manufacturing process for cathode materials in battery technology. Their research focuses on lithium-rich antiperovskites, which are known to be environmentally friendly, cost-effective and non-toxic cathode materials. Currently, these are usually produced by solid-state synthesis - a very costly and time-consuming process. A research group has now succeeded in producing this promising class of materials by simple ball milling. Dr. Nico Gräßler, postdoctoral researcher at the IFW Dresden, emphasizes: "This is a significant development for this still young class of cathodes, which will attract the interest of industry. Our mechanochemical process offers a number of advantages such as low energy consumption, safe handling and short synthesis time, as well as easy scalability of production. Our research meets the demanding criteria of the valid 12 Principles of Green Chemistry, which encourage sustainable and environmentally friendly chemistry." This development is another important step towards producing environmentally friendly and sustainable batteries, which are central to the energy transition and electromobility.

With their DFG-funded research, most recently published in the journal Green Chemistry, the scientists hope to continue improving the performance and environmental compatibility of energy storage devices and make a significant contribution to climate protection and increased energy efficiency.
