The challenge when dismantling a commonly used and convenient factor like wt.-% loading of additives in the electrolyte is that any reader will immediately ask: what is a better descriptor then? From a fundamental point of view it should be the surface area of the electrode where the additive reacts to form the solid electrolyte interphase (SEI). Hence we propose to use the ratio of the amount of substance of additive per electrode surface area. We herein estimated the surface area of the anode from a BET measurement of the used graphite which was reported by C-NERGY to be 4.1 m 2 /g and we assumed the effective anode area of the higher and lower mass loading to be roughly corresponding to the capacity loading. The amount of substance of the additives in the electrolyte were set through gravimetric mixing and verified by NMR. The internal resistance was measured from the voltage drop at 100 % SOC after a 30 min rest through a 2D discharge pulse as described in the methods section. The resulting data is shown in Figure . A clear difference is visible between the two electrode mass loadings. A better measure for providing a positive (instead of the negative proof in Figure ) for the feasibility and utility of the radd descriptor is still necessary. To this end we published the data of this study alongside the manuscript and invite the community to either find the "smoking gun" of the proposed electrode area dependent additive descriptor or to design a better and intuitive one.
