But in an electrolytic cell, these signs are reversed - the cathode is negative and the anode positive. This is because the cathode of the electrolytic cell is connected to the anode of the battery (and vice versa for the anode of the electrolytic cell, which connects to the battery cathode). This ensures the one thing that must be true.
