Thermal Cycling Impact on Supercapacitor Performance and Leakage Current under Constant Voltage Test
نویسندگان
چکیده
In this paper, we present a comparative study that focus on Supercapacitor (SC) thermal cycling and calendar ageing under constant voltage tests. The impacts of cycling temperature on SC performance and degradation rate are studied. Obtained results from thermal cycling ageing test are compared with those coming from simple calendar ageing test at constant voltage and constant temperature. The comparison method used is based on physics modelling parameters evolution in the Multi-Pore (MP) and the Constant Phase Element (CPE) models. Parameters are calculated based on experimental measurements results up to 13000 h of ageing test. The impact of thermal cycling during ageing tests on the measured leakage current is also presented.

متن کاملImpact of Pollution Location on Time and Frequency Characteristics of Leakage Current of Porcelain Insulator String under Different Humidity and Contamination Severity
One of the important factors influencing outdoor insulators performance is pollution phenomenon. The pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of Leakage Currents (LC) on the insulator surface, which may result in total flashover. The LC characteristics are affected by parameters such as nature and severity of pollution. Loca...

A three-dimensional modelling approach is used to study the effects of operating and ambient conditions on the thermal behaviour of the spiral wound supercapacitor. The transient temperature distribution during cycling is obtained by using the finite element method with an implicit predictor-multicorrector algorithm. At the constant current of 2A, the results show that the maximum temperature a...

متن کاملThermal Capacitive Electrochemical Cycle on Carbon-Based Supercapacitor for Converting Low-grade Heat to Electricity
It is a great challenge to efficiently convert low-grade heat (<100°C) to electricity. Currently available heat-to-current converters, such as thermoelectric generators, operating in a low-grade heat regime reach efficiencies no higher than a few percent (<3%). Herein, we illustrated a thermal capacitive electrochemical cycle (TCEC) using electrochemical cell, where the connection to the hot or...
