My question is quite straightforward: would a theoretical cell with fluorine and lithium yield the highest possible standard potential of all?
The table of Standard electrode potential in Wikipedia lists several potentials that are "better" than those of lithium and fluorine but I am skeptical about those values. The more common tables often list lithium with a potential of -3.040 volts and fluorine with a potential of 3.053 volts. Thus the standard potential gives 6.093 volts. However, can this number be improved? Are there materials that have more negative potentials than lithium or a higher potential than fluorine?
Please ignore the cost of the cell or practically.
