Beschreibung
Zusammenfassung:	Described herein is a composite comprising a fluorinated polymer and nanoparticles of lithium fluoride. The lithium fluoride has an average BET surface area of at least 10 m2/g. The fluorinated polymer includes a fluorinated polymer backbone chain and a plurality of groups represented by formula -SO2X, in which each X is independently -NZH, -NZSO2(CF2)1-6SO2X', -NZ[SO2(CF2)dSO2NZ]1-10SO2(CF2)dSO2X', or -OZ, and Z is independently a hydrogen, an alkali-metal cation, or a quaternary ammonium cation, X' is independently -NZH or -OZ, and each d is independently 1 to 6. A polymer electrolyte membrane, an electrode, and a membrane electrode assembly including the composite are also provided. L'invention concerne un composite comprenant un polymère fluoré et des nanoparticules de fluorure de lithium. Le fluorure de lithium présente une surface BET moyenne d'au moins 10 m2/g. Le polymère fluoré comprend une chaîne principale de polymère fluoré et une pluralité de groupes représentés par la formule -SO2X, dans laquelle chaque X est indépendamment -NZH, -NZSO2(CF2)1-6SO2X', -NZ[SO2(CF2)dSO2NZ]1-10SO2(CF2)dSO2X' ou -OZ, et Z est indépendamment de l'hydrogène, un cation de métal alcalin ou un cation d'ammonium quaternaire, X' est indépendamment -NZH ou -OZ, et chaque d est indépendamment de 1 à 6. L'invention concerne également une membrane électrolytique polymère, une électrode et un ensemble membrane-électrode comprenant le composite.
