Abstract (en)
[origin: ES8600789A1] The disclosure relates to activated metal anodes consisting essentially of zirconium, niobium, tantalum or titanium and having its surface area activated by means of metallic manganese the manganese content at the anode surface area of more than 16 weight % decreases towards the interior of the anode, reaching 0 weight % along a path corresponding to 1/4 of the thickness of the anode material, measured from the anode surface area. The disclosure also relates to a process for making these metal anodes.
