Current flow in batteries?

A battery consists of three things: a positive electrode, a negative electrode, and an electrolyte in between. The electrodes are made of materials that strongly want to react with each other; they are kept apart by the electrolyte. The electrolyte acts like a filter that blocks the flow of electrons, but allows ions (positively charged atoms from the electrodes) to pass

Al is an inexpensive, highly conducting material that is readily available in thin foils of high purity, and is the most widely studied and used positive electrode current collector for lithium batteries. Al is protected from continued corrosion in many electrolytes by a thin surface film formed by reaction of the metal with the electrolytic

Exchange current density at the positive electrode of lithium-ion
