Title
(EN) COATED IRON ELECTRODE AND METHOD OF MAKING SAME
(FR) ÉLECTRODE EN FER REVÊTUE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) Provided is an iron based electrode comprising a single layer of a conductive substrate coated on at least one side with a coating comprising an iron active material and a binder. The iron based electrode is useful in a Ni-Fe battery as the anode. The electrode can also be prepared by continuously coating each side of the substrate with a coating mixture comprising the iron active material and binder.
(FR) L'invention concerne une électrode à base de fer comprenant une monocouche d'un substrat conducteur revêtu au moins sur un côté avec un revêtement comprenant un matériau actif de fer et un liant. L'électrode à base de fer est utile en tant qu'anode dans une batterie Ni-Fe. L'électrode peut également être préparée en revêtant de façon continue chaque face du substrat avec un mélange de revêtement comprenant le matériau actif de fer et le liant.
