Title
(EN) INORGANIC ELECTROLYTE MEMBRANE FOR ELECTROCHEMICAL DEVICES, AND ELECTROCHEMICAL DEVICES INCLUDING SAME
(FR) MEMBRANE MINERALE A ELECTROLYTE POUR DISPOSITIFS ELECTROCHIMIQUES, ET DISPOSITIFS ELECTROCHIMIQUES LA COMPRENANT
Abstract
(EN)
The invention relates to an inorganic electrolyte membrane, wherein: the membrane is a porous membrane made of an electrically insulating metal or metalloid oxide including a first main surface (1) and a second main surface (2) separated by a body (3); through-pores or through-channels (4), which are open at the ends (5, 6) thereof and have a width of no greater than 100 nm, and which extend through the body (3) of the membrane and all of which are substantially parallel over the entirety of the body (3) of the membrane, connect the first main surface (1) and the second main surface (2); and an electrolyte, in particular a polymer electrolyte, is confined within the pores (4) of the membrane. The invention further relates to an electrochemical device, in particular a lithium metal or lithium-ion battery including said membrane.
(FR)
Membrane minérale à électrolyte dans laquelle: -la membrane est une membrane poreuse en un oxyde de métal ou de métalloïde isolant électrique comprenant une première surface principale (1) et une deuxième surface principale (2) séparées par une épaisseur (3); -des pores ou canaux traversants (4) ouverts à leurs deux extrémités (5,6), d'une largeur inférieure ou égale à 100 nm, orientés dans le sens de l'épaisseur (3) de la membrane et tous substantiellement parallèles,sur la totalité de l'épaisseur (3) de la membrane,relient la première surface principale (1) et la deuxième surface principale (2); et -un électrolyte, notamment un électrolyte polymère est confiné dans les pores (4) de la membrane. Dispositif électrochimique notamment accumulateur Lithium métal ou Lithium-ion comprenant ladite membrane.
