Title (EN) SELF-FORMING METAL HALIDE ELECTRODE, AND ASSOCIATED PRODUCTION METHOD
(FR) ELECTRODE EN HALOGÉNURE DE MÉTAL AUTO-FORMÉE ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract:
(EN) The invention relates to a method for the production of a positive electrode intended for use in an alkali metal-ion electrochemical device. The method comprises the synthesis of a layer (5) of a metal halide, involving the electrochemical treatment of a current collector (1). The electrochemical treatment of the method involves the spontaneous corrosion of the current collector. The invention also relates to an electrochemical device adapted to be the seat of the spontaneous corrosion reaction of the method of the invention.
(FR) L'invention se rapporte à un procédé de fabrication d'une électrode positive destinée à être utilisée dans un dispositif électrochimique à ion de métal alcalin. Le procédé comprend la synthèse d'une couche (5) d'un halogénure de métal par traitement électrochimique d'un collecteur de courant (1). Le traitement électrochimique de ce procédé est une corrosion spontanée du collecteur de courant. L'invention se rapporte également à un dispositif électrochimique adapté pour être le siège de la réaction de corrosion spontanée objet du procédé de l'invention.
