Abstract:
     The Al-Mn alloy foil as negative electrode material contains such components (Wt.%) as Cu (0.15-0.30), Mg (0.02-0.08), Mn (1.0-1.6), Zn, Fe, Si and Al and is made up through proportioning, casting, homogenizing at 580-620 deg.C, hot rolling at 480-520 deg.C, cold rolling and intermediate annealing at 350-450 deg.C. The finished foil with 0.04-0.05 mm in thickness has faster corrosion speed to form uniform porous corroded surface and high specific capacitance.
