Moreover, the porous electrode structure in practical LIBs further complicates the analysis of the diffusion impedance . Sikha and White derived an analytical impedance model taking into account the porous structure, the solution-phase diffusion and the solid-state diffusion. On the basis of the Sikha-White model, Woillez et al. proposed a simplified framework to analyze the convoluted diffusion impedance of LIBs, which consists of solid-state diffusion and liquid-phase porous diffusion. Although the analytical model provides a robust way to analyze impedance data of LIBs, it requires specific input parameters of the studied system which are often not accessible in most application scenarios.
