Moisture-tolerant, Fluorine-free Electrolytes for Scalable and Sustainable Batteries

The MOFESS project proposes developing innovative moisture-tolerant, fluorine-free electrolytes to enhance the sustainability and safety of rechargeable batteries. Challenging traditional battery chemistry, it employs high-entropy electrolytes and water-in-salt concepts to transcend current limitations on conductivity and stability. Utilizing computational screening paired with high-throughput experimentation, this research aims to create innovative battery chemistries that offer enhanced safety, environmental sustainability, and economic viability. MOFESS will explore a vast array of non-fluorinated salts and solvent combinations. The goal is to discover and optimize electrolyte formulations that are not only moisture-tolerant but also match the performance of existing lithium-ion and sodium-ion batteries, without the drawbacks of toxic and costly fluorine-based components.
