Supercapacitor, izwi kandi nka ultracapacitor cyangwa amashanyarazi ya Double-Layeri、Ubushobozi bwa zahabu、capacitor ya farad. Ububiko bubika ingufu hakoreshejwe uburyo bwa static butandukanye na reaction ya electrochemic.Gukoresha voltage itandukanye kuri plaque nziza kandi mbi yishyuza capacitor.
Nibintu byamashanyarazi, ariko ntabwo bigira ingaruka kumiti mugikorwa cyo kubika ingufu, bikaba bidasubirwaho, niyo mpamvu super-capacator zishobora kwishyurwa inshuro nyinshi kandi zikarekurwa inshuro ibihumbi magana.
Ibice bya super capacitor birashobora kugaragara nkibisahani bibiri bidakora neza bya elegitoronike ya electrode, ku isahani, amashanyarazi, isahani nziza ikurura ion mbi muri electrolyte, isahani mbi ikurura ion nziza, mubyukuri igizwe nububiko bubiri bwa capacitive.Ibintu byiza bitandukanijwe ni hafi yisahani itari nziza, na ion zitari nziza ziri hafi yisahani nziza.
