Discharge has constant discharge and constant resistance discharge, constant discharge is in fact in the external circuit plus a variable resistance that can change with the voltage, the essence of constant resistance discharge is to add a resistance to the positive and negative terminals of the battery to let electrons through. As long as the electrons on the negative terminal cannot travel from the negative terminal to the positive terminal, the battery will not discharge. Electrons and Li+ are action at the same time, the same direction but the road is different, discharge, electrons from the negative electrode through the electronic conductor to the positive electrode, lithium ion Li+ from the negative "jump" into the electrolyte, "climb" the diaphragm on the curved hole, "swim" to the positive electrode, and long run over the electron together.
