摘要:
Procédé de fabrication en continu d'une électrode comprenant les étapes suivantes réalisées simultanément et en continu : a) Défilement continu d'un collecteur de courant (10), le collecteur de courant ayant au moins un trou traversant non ébavuré, b) Dépôt en continu d'une encre (30) sur la première face du collecteur de courant (10), l'encre (30) comprenant au moins un solvant et un matériau actif (20) d'électrode, c) Aspiration en continu de l'encre (30) déposée, à travers le collecteur de courant (10), par un système d'aspiration (50), pour éliminer le solvant, de manière à former une électrode, l'épaisseur de l'électrode étant supérieure au rayon du trou traversant, un filtre (40) étant disposé entre le collecteur de courant (10) et le système d'aspiration (50), le filtre (40) ayant des tailles de pores allant de 0,1µm à 50µm, et de préférence de 0,2µm à 5µm, de manière à retenir le matériau actif (20).
