Supercapacitor, wanda kuma aka sani da ultracapacitor ko Electrical Doule-Layer Capacitor,Gold capacitor,farad capacitor.A capacitor yana adana makamashi ta hanyar cajin a tsaye sabanin abin da ake kira electrochemical.Aiwatar da bambancin wutar lantarki akan faranti masu inganci da mara kyau yana cajin capacitor.
Sinadarin sinadari ne na lantarki, amma ba ya fuskantar halayen sinadarai a cikin tsarin adana makamashi, wanda ke iya jujjuya shi, shi ya sa za a iya maimaita cajin supercapacitors da fitar da su dubban daruruwan lokuta.
Pieces na super capacitor za a iya gani a matsayin biyu ba-reactive porous electrode faranti, a kan farantin, lantarki, tabbatacce farantin jawo korau ions a cikin electrolyte, korau farantin jawo m ions, a zahiri kafa biyu capacitive ajiya Layer.The rabu tabbatacce ions ne. kusa da farantin mara kyau, kuma ƙananan ions suna kusa da farantin mai kyau.
