We analize electrochemical LiFePO4 cells with impedance spectroscopy and incremental capacity analysis in order to establish a correlation with capacity fade. We found that polarization and diffusion impeances increased with aging, but at different rates depending on the aging stage. This aging stage dependence was also found in ICA analyzes, where the lithium intercalation was investigated. A correlation with capacity decrease measured with Coulomb counting was established.Postprint (author's final draft)
