Дослідження роботи суперконденсатора в рамках дволанкової RC-моделі

Abstract

The investigation covers the research of inner resistance dependence on time on-stream. We have suggested the model of supercapacitor, which describes of variation with time of its key parameters at different operative conditions, as opposed to traditional one. According to this model, we have succeeded to interpret the causes of appearance of two inner resistance parts (ESR & EDR) and find out the time limits for using ones. Received experimental data allowed deducing, that time distribution of inner resistance (ESR & EDR) is proper of all electrochemical systems where using porous electrodes.
