Seizing the high ground for LR1130 battery, Swiss research institute Empa is committed to developing solid-state electrolytes

According to foreign media reports, at the beginning of this year, Germany’s Fraunhofer Institute ISC and the Swiss Federal Materials Testing and Research Laboratory (Empa) cooperated to launch a project called IE48, which is suitable for mass production. LR1130 battery for electric vehicles lay the foundation. The project builds on the strengths of two research partners: Empa, headquartered in Dübendorf, Switzerland, which provides the chemical and physical basis for the new battery technology; and Empa, headquartered in Würzburg, Germany. The Raunhof Ceramic Institute provides know-how in process development and battery production, including battery prototype production. According to the two partners, a leap forward in solid-state battery technology presents an opportunity for Europe to bring key technologies that were previously firmly in the hands of Asian companies. According to an accompanying press release: "Such LR1130 battery do not require flammable liquid electrolytes, thus providing significant operational stability. In addition, they have advantages in size and weight, so they do not require overly complex Safe battery housing. "By using metal anode materials instead of the currently commonly used graphite anodes, batteries can have higher energy density and shorter charging times. According to scientists at the Fraunhofer Institute for Silicate Research, the individual components of future LR1130 battery are already well studied in the laboratory, but the biggest challenge is integrating them into a stable system, the foundations of which will be laid within the framework of the IE4B project (Interface Engineering for Safe and Sustainable High-Performance Batteries). Specifically, Empa is working on developing solid-state electrolytes, producing thin films with customized electronic properties and developing nanostructured anode materials. The Fraunhofer Institute for Silicates researches lithium-conducting polymers and protective layers composed of sol-gel materials. It is also responsible for the development, production and testing of battery prototypes and small-scale batteries. From the beginning of the project, German and Swiss industrial companies such as Heraeus, Buhler Group, Applied Materials, Varta and ABB participated in the project. within, supporting the project from an industrial perspective.
