A battery that is recharging or an electrolytic cell performing electrolysis has its cathode as the negative terminal, from which current exits the device and returns to the external generator as charge enters the battery/ cell. For example, reversing the current direction in a Daniell galvanic cell converts it into an electrolytic cell , Daniell cell can be reversed to, technically, produce an electrolytic cell. where the copper electrode is the positive terminal and also the anode.
