Just to make clear, the nickel was always on the + side of the power supply, and is described in Wikipedia as the cathode. Hmm . I'm usually the mildly dyslexic one, but someone is confused: the + or positively charged electrode is the "anode" in an electrolytic cell, which is what we are talking about - and the "cathode" is negative (attracts protons and positive ions). In a battery, this terminology is reversed, which is probably what they are referring to. Technically a battery is a galvanic cell, not an electrolytic cell, since it supplies power. However, to confuse things even more, when the battery is being charged, instead of supplying charge, it becomes electrolytic. You could win a bet on that one (or lose it).
