Title

PRECURSOR INFILTRATION AND COATING METHOD
(FR)
INFILTRATION DE PRECURSEUR ET PROCEDE DE REVETEMENT
Abstract:
(EN)
A method of forming a composite (
e.g
., a mixed electrode) by infiltration of a porous structure (
e.g
., one formed from an ionically conductive material) with a solution of a precursor (
e.g.
, for an electronically conductive material) results in a particulate layer on and within the porous structure with a single infiltration. The method involves forming a solution comprising at least one metal salt and a surfactant; heating the solution to substantially evaporate solvent and form a concentrated salt and surfactant solution; infiltrating the concentrated solution into a porous structure to create a composite; and heating the composite to substantially decompose the salt and surfactant to oxide and/or metal particles. The result is a particulate layer on the pore walls of the porous structure. In some instances the particulate layer is a continuous network. Corresponding devices have improved properties and performance.
(FR)
L'invention concerne un procédé de formation d'un composite (par ex., une électrode mélangée) par infiltration d'une structure poreuse (par ex., une structure formée à partir d'une matière conductrice d'ions) avec une solution d'un précurseur (par ex., pour une matière conductrice sur le plan électronique), ledit procédé se soldant par une couche de particules sur et au sein de la structure poreuse avec une seule infiltration. Ce procédé consiste à former une solution contenant au moins un sel de métal et un agent de surface, à chauffer ladite solution pour faire sensiblement évaporer le solvant et former un sel concentré et une solution d'agent de surface, à infiltrer la solution concentrée dans une structure poreuse afin de créer un composite, et à chauffer le composite de manière à décomposer le sel et l'agent de surface en oxyde et/ou particules métalliques. Il en découle la formation d'une couche de particules sur les parois poreuses de ladite structure poreuse. Dans certains exemples, la couche de particules forme un réseau continu. Cette invention a aussi pour objet des dispositifs associés possédant des propriétés et une efficacité accrues.
