Abstract

Al foil for use as electrode in an electrolytic condenser consists of core layer(s) inhibiting the growth of etching cavities on electrolytic etching and outer layers, on both sides of the core, which form numerous etching cavities. The core can contain more Fe than the outher layers, be coated with Al (hydr)oxide or contain Al (hydr)oxide particles. The foil has great mechanical strength, esp. folding strength, and, at the same time, max. surface area.
