Modelling of degradation and a soft failure moment during the operation of a supercapacitor applying selected diffusion processes

Our intention is to determine a capacity degradation threshold and the moment the soft failure of a graphite supercapacitor (SC) occurs. If we do not take into account the idle state, the functioning of the supercapacitor m...
