Title (EN) ALUMINUM ALLOYS FOR USE IN ELECTROCHEMICAL CELLS AND METHODS OF MAKING AND USING THE SAME
(FR) ALLIAGES D'ALUMINIUM UTILES DANS DES CELLULES ÉLECTROCHIMIQUES ET PROCÉDÉS DE FABRICATION ET D'UTILISATION ASSOCIÉS
Abstract:
(EN) New aluminum electrode alloys and methods of making the same are disclosed. In one embodiment, a method comprises, casting an aluminum alloy into an as-cast product, wherein the aluminum alloy comprises from 0.005 wt. % to 0.06 wt. % Fe, and forming the as-cast product into an aluminum electrode alloy. The casting step may comprise solidifying at a solidification rate. The solidification rate may be at or above a threshold solidification rate. The threshold solidification rate is sufficient to achieve not greater than 0.04 vol. % of Fe particles.
(FR) L'invention concerne de nouveaux alliages d'électrodes d'aluminium et des procédés de fabrication associés. Dans un mode de réalisation, un procédé comprend la coulée d'un alliage d'aluminium en un produit sous la forme d'un produit coulé, l'alliage d'aluminium comprenant de 0,005 % en poids à 0,06 % en poids de Fe et la formation du produit sous forme de produit coulé en alliage d'électrode d'aluminium. L'étape de coulage peut comprendre la solidification à un certain taux de solidification. Le taux de solidification peut être supérieur ou égal à un taux de solidification seuil. Le taux de solidification seuil est suffisant pour ne pas atteindre plus de 0,04 % en volume de particules de Fe.
