A parallel but highly-relevant development pointed out the role of "liquid Madelung potential" in single-ion reactivity. It has been recently shown that the reduction potential of Li + ions deviates significantly from the Nernstian behaviour in highly concentrated LiFSI/ethylene carbonate solutions and correlates very well with the liquid Madelung potential, 11 i.e. the Coulombic potential experienced by the cation due to the surrounding ions in liquid phase. The computed liquid Madelung potential using classical force fields indicates an increment of about 400 mV when increasing the salt concentration from 0 to 8 m, which is not too different from the shift in the OCV mentioned previously for aqueous electrolyte solutions. Given that both ethylene carbonate and water are polar liquids with high dielectric constants, it would be very interesting to see what is the role of liquid Madelung potential in aqueous electrolytes.
