If discharge time is higher than charge time in a supercapacitor for three-electrode system. Then, how can explain it? Is it correct or not? Please respond as soon as possible.
It is three electrode set up in which silver/silver chloride reference, platinum as counter and graphite act as a working electrode. For charge it take 140 seconds and for discharging it take 160 seconds at 0.5 to - 0.5 V potential window
Ideally, the charging and discharging time of a supercapacitor are equal. I suggest you to please check the current vs. time graph as well in order to reconfirm the parameters inserted for each.
