I-supercapacitor, eyaziwa nangokuthi i-ultracapacitor noma i-Electrical Doule-Layer Capacitor,I-Gold capacitor,I-farad capacitor.I-capacitor igcina amandla ngeshaja emile ngokuphambene nokusabela kwe-electrochemical.Ukusebenzisa umehluko we-voltage kumapuleti amahle kanye nama-negative kushaja i-capacitor.
Iyingxenye ye-electrochemical, kodwa ayihlanganisi ukusabela kwamakhemikhali ohlelweni lokugcina amandla, abuyiselwa emuva, yingakho ama-supercapacitor angashajwa ngokuphindaphindiwe futhi akhishwe izikhathi ezingamakhulu ezinkulungwane.
Izingcezu ze-super capacitor zingabonakala njengamapuleti amabili e-electrode angenawo amandla asebenzayo, epuleti, ugesi, ipuleti elihle liheha ama-ion angalungile ku-electrolyte, ipuleti elibi liheha ama-ion amahle, empeleni lakha ungqimba lwe-capacitive wokugcina.I-ion ehlukanisiwe eduze kwe-negative plate, futhi ama-ion anegethivu aseduze ne-positive plate.
