文摘

In-depth and stepwise study of the interfacial impedance of graphite-based anodes. Application of de Levie&rsquo;s model to account for porosity effects in Li-ion batteries. The use of SEI reinforcing additives for a better interpretation of the EIS response. Spotting the physical phenomena causing unexpected resistance drop during battery ageing.
