Modelling of current and temperature effects on supercapacitors ageing. Part I: Review of driving phenomenology

摘要: The paper proposes a study of the phenomenology driving ageing mechanisms electrochemical double layer supercapacitors (SCs) during their most common operating conditions. In particular, focuses on so-called life endurance (LE) and power cycling (PC) stresses. first provides description variables governing SC behaviour at microscopic scale (i.e., porosity electrode surface, diffusion conductivity electrolyte). Then, discusses link between these ones describing macroscopic temperature electrolyte delivered current). This analysis is applied to both LE PC stresses as well combination. discussions make reference experimental results obtained Author’s laboratory by means dedicated test bench.
