Title (EN) CERAMIC GARNET BASED IONICALLY CONDUCTING MATERIAL
(FR) MATÉRIAU CONDUCTEUR IONIQUE À BASE DE GRENAT CÉRAMIQUE
Abstract:
(EN) Disclosed is a ceramic material having a formula of LiwAxM2Re3-yOz, wherein w is 5 - 7.5; wherein A is selected from B, Al, Ga, In, Zn, Cd, Y, Sc, Mg, Ca, Sr, Ba, and any combination thereof; wherein x is 0 - 2; wherein M is selected from Zr, Hf, Nb, Ta, Mo, W, Sn, Ge, Si, Sb, Se, Te, and any combination thereof; wherein Re is selected from lanthanide elements, actinide elements, and any combination thereof; wherein y is 0.01 - 0.75; wherein z is 10.875 - 13.125; and wherein the material has a garnet-type or garnet-like crystal structure. The ceramic garnet based material is ionically conducting and can be used as a solid state electrolyte for an electrochemical device such as a battery or supercapacitor.
(FR) L'invention concerne un matériau céramique de formule LiwAxlVhRes-yOz, w étant compris entre 5 et 7,5 ; A étant choisi parmi B, Al, Ga, In, Zn, Cd, Y, Sc, Mg, Ca, Sr, Ba, et toute combinaison de ceux-ci ; x étant compris entre 0 et 2 ; M étant choisi parmi Zr, Hf, Nb, Ta, Mo, W, Sn, Ge, Si, Sb, Se, Te, et toute combinaison de ceux-ci ; Re étant choisi parmi les lanthanides, les actinides, et toute combinaison de ceux-ci ; y étant compris entre 0,01 et 0,75 ; z étant compris entre 10,875 et 13,125 ; et le matériau ayant une structure cristalline de type grenat ou similaire au type grenat. Le matériau à base de grenat céramique est conducteur d'ions et peut être utilisé comme électrolyte à l'état solide pour un dispositif électrochimique tel qu'une batterie ou un supercondensateur.
