The ageing behaviour of electric double layer (EDLC) supercapacitors during over-temperature and over-voltage stresses is described. Specific experimental tests were carried out in order to reproduce, under laboratory controlled conditions, the above-mentioned stresses. The obtained results are discussed and interpreted to define indicators that distinguish(More)
a r t i c l e i n f o A brief overview of the literature relating to electrochemical studies and processes undertaken in supercritical fluids is presented. This review mostly concerns carbon dioxide and hydrofluorocarbons, given the accessibility of their supercritical states, and does not consider the emerging body of research in expanded phase(More)
— This paper focuses on the description of the behavior of supercapacitors during over-temperature and over-voltage stresses and the consequent ageing processes. Specific physical evidences supporting the explanation of the experimental findings are provided and discussed in the paper. A method to distinguish between over-temperature and over-voltage(More)
Social, economic, and political pressures are causing a shift in the global energy mix, with a preference toward renewable energy sources. In order to realize widespread implementation of these resources, large-scale storage of renewable energy is needed. Among the proposed energy storage technologies, redox flow batteries offer many unique advantages. The(More)
