There is an explanation of how a battery works that says that in a battery circuit, the electrons do a complete loop and, given enough time, they can return to their starting point. This theory says that when the electrons arrive in the positive terminal and they lost all of their potential energy, the battery does work on the electrons to put them back in the negative terminal so they are full of potential energy and reenter the circuit.
But, is this theory true? If it is, could someone explain me how? From what I understand of batteries, there aren't any electrons that move from the positive terminal to the negative terminal of the battery. The electrons of the circuit can come from the molecules of the anode and once they reach the positive terminal there is nothing else happening except that they detach from the positive electrode and make the electrolyte ions neutral. They stop at the electrolyte. They don't return to the negative terminal.
This theory is on the two last paragraphs here : http://www.physicsclassroom.com/class/circuits/Lesson-1/Electric-Potential
