Impact of Fluorine Content on Structure, Redox, and Electrochemical Performance of Disordered Rock-Salt Li1.25Mn0.5+ y /2Nb0.25– y /2O2– y F y Electrode Materials

Abstract Disordered rocksalt (DRS) oxides are highly promising positive electrode materials for next-generation Li-ion batteries, yet their practical application is severely bottlenecked by the irreversibility of oxygen-redox processes. Fluorination (O2– by F– substitution) repre...

New mechanistic insights into the widely used LiPO2F2 additive enabled by ultra-high-resolution FTICR-MS

Understanding how electrolyte additives influence the formation and evolution of the solid electrolyte interphase (SEI) is essential for improving the durability of lithium‑ion batteries. In this work, we investigate the role of lithium difluorophosphate (LiPO2F2, LiDFP) in 1 M L...

An airborne in-situ dataset of cloud microphysical properties in supercooled large droplet icing conditions

Abstract. Detailed and comprehensive data sets on microphysical cloud properties in icing conditions are rare. In April 2023, fifteen research flights were performed with the SAFIRE ATR 42 research aircraft during the SENS4ICE-EU airborne measurement campaign over France and adja...
