It doesn't help that very many explanations on the web of anode/cathode are wrong, or at least misleading, and only cover catalytic or galvanic cells.
I believe https://chemistry.stackexchange.com/questions/16785/positive... is correct.

The terms anode and cathode should be burned. We don't use them much in modern electronics. E.g. we don't say that the positive power pins of a CPU are anodes, or that ground pins are cathodes.
