Title (EN) A METHOD FOR MANUFACTURING A NANOPARTICLE MATERIAL AND A FLUORIDE ION BATTERY
(FR) PROCÉDÉ DE FABRICATION D'UN MATÉRIAU NANOPARTICULAIRE ET BATTERIE AUX IONS FLUORURE
Abstract:
(EN) The present invention provides a method for manufacturing a nanopartic!e material having an ionic conductivity as a battery material for Fluoride ion Batteries, thus, being capable for overcoming high resistances at the surfaces, grain-boundaries of nanoparticles or compartments of the nanoparticles by a material treatment selected from: (i) a ball-mill procedure under aerosol and/or vapour-pressure atmosphere, (jj) excess-synthesis, (iii) ball-milling with surface stabilizing and conductivity enhancing solid or/and gel/liquid additives or (iv) functionalizing the material to obtain functionalized nanoparticles (GSNP) comprising a dispersion of graphene, nanotubes and/or a further additive selected from carbon-black, graphite, Si and/or CFX, Herein, fluorides (EmmFh), fluorides composites (Em1m1Em2m2...Fh1) are synthesised, wherein a first metal, metalloid or non-metal Em or Em1 and a second metal, metalloid or non-metal Em2 are dissimilarly selected from Cu, Pb, Fe, Sn, Zn, Bi, Cd, Co, Cr, Ni, Sb, C, Si, B. P, N, Ge, Ce, Se, Ca, Mg, Li, Na, K, Al, Sr, Ba, La, Sm, Eu, Cs, Gd or Y in a manner that a battery material having an increased ionic conductivity is obtained.
(FR) La présente invention concerne un procédé de fabrication d'un matériau nanoparticulaire ayant une conductivité ionique en tant que matériau de batterie pour des batteries aux ions de fluorure, qui est ainsi capable de surmonter des résistances élevées aux surfaces, aux joints de grain de nanoparticules ou de compartiments des nanoparticules par un traitement de matériau choisi parmi : (i) une procédure de broyage à boulets dans une atmosphère d'aérosol et/ou de pression de vapeur, (jj) une synthèse en excès, (iii) un broyage à boulets à l'aide d'additifs solides et/ou sous forme de gel/liquide stabilisant la surface et améliorant la conductivité ou (iv) une fonctionnalisation du matériau pour obtenir des nanoparticules fonctionnalisées (GSNP) comprenant une dispersion de graphène, des nanotubes et/ou un autre additif choisi parmi le noir de carbone, le graphite, le Si et/ou le CFx. Des fluorures (EmmFh), des composites de fluorures (Em1m1Em2m2...Fh1) sont synthétisés, un premier Em ou Em1 métallique, métalloïde ou non métallique et un second Em2, métallique, métalloïde ou non-métallique étant choisis de manière non similaire parmi les éléments suivants : Cu, Pb, Fe, Sn, Zn, Bi, Cd, Co, Cr, Ni, Sb, C, Si, B, P, N, Ge, Ce, Ca, Mg, Li, Na, K, Al, Sr, Ba, La, Sm, Eu, Cs, Gd ou Y de telle sorte qu'un matériau de batterie ayant une conductivité ionique accrue est obtenu.
