Supercapacitor Degradation and Reliability
Original language description
Degradation of supercapacitor (SC) is analyzed by accelerated aging test. Evolution of SC parameters is determined before the aging test, and during up to 8x10 5 cycles of both 75% and 100% energy cycling. Capacitance fading, equivalent series resistance (ESR) increase, and leakage current trend are analyzed for off-the-shelf CapXX SC. Presented model consists of five parameters. These are Helmholtz and diffuse double layer capacitances, esponsible for SC overall capacity. Next there is time dependent resistance in between Helmholtz and diffuse capacitances. And an ordinary ESR, and resistance responsible for SCs leakage current. Fading of both capacitances is modeled by exponential equation. Increase of ESR AC component is modeled by linear function.
