WebThe distribution of relaxation times (DRT) has emerged as one of the main methods for the analysis of EIS spectra. Gaussian processes can be used to regress EIS data, quantify uncertainty, and deconvolve the DRT, but current implementations do not constrain the DRT to be positive and can only use the imaginary part of EIS spectra. WebNov 3, 2024 · The EIS spectra were recorded under galvanostatic control of the overall cell. Frequency range was from 0.05 Hz to 10 kHz with 11 steps per decade. The amplitude of sinusoidal current perturbation signal was chosen in a such way that it resulted in a cell voltage response of 10 mV or lower. Impedance Model
