FLUFFY

FLUFFY aims to accelerate stationary energy storage research by developing better components for sodium-ion batteries by identifying fluoride-based cathode materials that enhance the functionality of sodium-ion batteries.

The FLUFFY project aims to accelerate stationary energy storage research by developing cathodes for advanced sodium-ion batteries. With the increasing reliance on weather-dependent renewable energy sources, it is essential to establish a reliable energy storage system to guarantee a steady supply of clean energy. Sodium-ion batteries have emerged as a promising and sustainable solution due to their relatively high volumetric energy density, long cycle life, and cost-effectiveness.

The FLUFFY project will focus on identifying fluoride-derived materials as cathode materials that maximize the electrochemical performance, lifetime and minimize the environmental footprint of sodium-ion batteries. The high electronegativity of fluorine enhances the electrochemical performances and chemical stability, making these materials ideal for battery applications. Our mixed-anion approach will further modify the fluoride chemistry to increase ionic and electronic conductivity. The project’s multidisciplinary approach brings together a diverse team of researchers with a solid background in solid-state chemistry, battery materials, electrochemistry, modelling and operando techniques. These experts will work together to synthesize and study the electrochemical behaviour of fluoride-derived materials in real-time using operando techniques, making a significant contribution to energy storage technology.
