Abstract：Supercapacitor,as a new energy reserve device,achieves energy storage and release through the reversible physical charge transfer process between electrodes.It is also developing rapidly,and its research on its performance and application has gradually deepened the superca-pacitor as a backup power source.Rapid,large capacity,long cycle life,etc.,are widely used in consumer electronics,electric vehicles and hybrid cars,power systems and other fields.In the study of various performance parameters of supercapacitors,equivalent series resistance is a very important indicator,used to determine the super capacitor electrode failure problem.In this pa-per,through the introduction of the internal structure of the supercapacitor,the analysis of the working principle of the supercapacitor and the composition,principle and influencing factors of the equivalent internal resistance of the supercapacitor are helpful to judge the failure of the su-percapacitor more accurately.
