| Abstract: | Based on electric vehicle battery test criterion, the time-sequence of constant-current charging/ discharging cycle test for supercapacitors was applied. Under the experiment of high current charge/discharge cycle lifetime,the characteristics attenuation of the available capacity and charging/discharging duration of supercapacitors were studied. And also some failure modes for deflagration and shell softening were explored, which were caused by heat energy cumulation and electrical-thermal breakdown. |

| Keywords: | supercapacitor rapid charging/discharging cycles performance attenuation failure modes |
