A water-degradable electrode, its method of preparation and a method of reclaiming valuable metal or metal alloy from such water-degradable electrode after use are provided. The water-degradable electrode (100) contains a water-degradable, electrically nonconductive substrate (110) and a nonphotosensitive, electrically conductive layer (140) containing a metal or metal alloy. The metal- or metal-alloy-containing, nonphotosensitive, electrically conductive layer is disposed on the water-degradable nonconductive substrate. After the electrode has been used, the nonphotosensitive, electrically conductive material can be reclaimed by degrading in water the electrically nonconductive substrate on which the conductive material is disposed.
