A relevant point to note is that to fit the data in Figure , Equation ( ) was applied. When considering equation ( ) instead, i.e. 𝝀 not necessarily equal to one (Figure ), 𝝀 values are determined to be between 0.9 and 1.2 (Figure ). To compare the experimental results with the simulations displayed in Figure , the tortuosity of the experimental electrodes was obtained through the impedance analysis described in the methods section and schematized in the top row of the scheme in Figure . Three porosity values were selected, 28 %, 38 % and 48 %, for each of the AM percentages and for each porosity, six coin cells in symmetric cell configuration were produced. All samples for each AM content were cut from the same deposition, and the adjustment of the porosity was done through calendering at different thicknesses. Representative Nyquist plots of the EIS obtained for each porosity and AM content are displayed in Figure .
