Work done by a battery to move charge

[QUOTE="ehild, post: 4868400, member: 481"] Think of the process happening in the battery when charging the capacitor. There is some charge piled on the electrodes of the battery in stationary case.The voltage across the capacitor plates is equal to V, the voltage of the battery. Dynamic equilibrium is maintained at the interface between the electrode and electrolyte inside the battery: The chemical forces driving ions to the electrode or to the electrolyte are balanced by the electric forces. When inserting the dielectric between the capacitor plates, the voltage decreases between the plates, and electrons flow from the negative terminal of the battery to the capacitor, and from the capacitor to the positive terminal, decreasing the charge on the electrodes, so allowing the chemical forces to drive new ions to the electrodes. At the end the charge which was given to the capacitor appears on the electrodes again and equilibrium is set up. The net process is that some charge was driven from the negative terminal to the positive one by some chemical work. That work is equal to QV. [/QUOTE]
