a) Integral capacitance for the positive, negative and total electrodes versus the mole fraction of EMI‐BF₄ in the EMI‐BF₄/EMI‐TFSI (x) from coarse‐grained classical DFT; operating potential window fixed as 3.0 V between two electrodes. b) Experimental integral capacitance versus x for a symmetric EDLC operating at 3.0 V at different scan rates. Note that only the right y‐axis can be directly compared between (a) and (b) panels. Reproduced with permission.73 Copyright 2016, American Chemical Society.
