Estimate the capacitance of capacitors
In the case of different electrodes in the capacitor, the higher capacitance lowers its potential, while the weaker electrode is charged over a larger voltage range ΔU = Q/C. In organic solvents, the cation (tetraethylammonium or 1-ethyl-3-methylimidazolium) on the negative electrode determines the total capacitance of the supercapacitor C ≈ C ⊖ (see Table 3 ). - Download [PDF]
