Fig. 10: Cell voltage contributions at different applied working potentials.
From: The Effect of Applied Potential on the Li-mediated Nitrogen Reduction Reaction Performance
Equilibrium potentials of Li+ reduction and THF oxidation are taken as Eeq,Li/Li+ = −3.02 V and Eeq,THF = +1.00 V, respectively. The ohmic overpotential is calculated via ηohmic = IRΩ (RΩ = 71 Ω, Supplementary Fig. 26) and the electrode overpotential is the remaining voltage contribution after subtraction (ηelect = Ecell - Eeq - ηohmic). Data is based on the chronoamperometry measurements in Supplementary Fig. 7.
