It is important to note that the potential is not doubled for the cathode reaction, even though a "2" stoichiometric coefficient is needed to balance the number of electrons exchanged. Also, the standard cell potential (Eºcell) for a battery has always a positive value, that is, Eºcell > 0 volts.That is because the redox reaction between the …
17.2: Galvanic Cells
The magnesium electrode is an active electrode because it participates in the oxidation-reduction reaction. Inert electrodes, like the platinum electrode in Figure (PageIndex{3}), do not participate in the oxidation-reduction reaction and are present so that current can flow through the cell. Platinum or gold generally make good inert ...

Designing better battery electrolytes
You need a positive electrode, you need a negative electrode, and — importantly — you need an electrolyte that works with both electrodes. An electrolyte is the battery component that transfers ions — charge-carrying particles — back and forth between the battery''s two electrodes, causing the battery to charge and discharge. For …
