Furthermore, modern, state-of-the-art electrochemical workstations afford the collection of highquality EIS data with limited experimental expertise. Despite these advantages, interpreting EIS spectra remains a considerable challenge . The analysis is usually performed by fitting spectra against equivalent circuits models (ECMs) . However, ECMs are often just circuit analogs and lack uniqueness . Alternatively, physical models can be used, but these models are systemspecific and significantly more difficult to implement . To overcome these challenges, the distribution of relaxation times (DRT) has emerged as a complementary method enabling the identification of the characteristic timescales in EIS spectra . Explicitly, within the DRT analysis framework, the impedance model, 𝑍 DRT (𝑓), is fashioned to originate from relaxations, leading to the following expression :
