CA 2058431

A method for producing a Li(A1) anode for a lithium battery comprises the steps of pyrometallurgically alloying Li and A1 in inert atmosphere, grinding the formed alloy after cooling to a homogeneous powder, pressing or extruding the powder to an elongated anode element around a current conductive thread, preferably of nickel, and providing the anode element with an enclosure of microporous separator material.

Un procédé de production d'une anode Li(Al) pour une pile au lithium comprend les étapes consistant à allier de manière pyrométallurgique Li et Al dans une atmosphère inerte, à broyer l'alliage formé après refroidissement jusqu'à obtention d'une poudre homogène, à presser et à extruder ladite poudre jusqu'à obtention d'un élément d'anode allongé (2) autour d'un fil (1) conducteur de courant, de préférence en nickel, et à doter ledit élément d'anode d'une enveloppe (3) de matière de séparation microporeuse.
