Ma supercapacitor amatchedwa magetsi awiri osanjikiza capacitors ndi farad capacitors, omwe apangidwa kuyambira 1980s.Mosiyana ndi ma capacitor achikhalidwe, ma supercapacitors ndi mtundu watsopano wa ma electrochemical capacitors, omwe ali pakati pa ma capacitor ndi mabatire, ndipo samakumana ndi machitidwe amankhwala panthawi yosungira mphamvu.
Ma Supercapacitor ali ndi mawonekedwe othamanga mwachangu, kuthamangitsa ndi kutulutsa kambirimbiri, kusungirako mphamvu, kuteteza chilengedwe komanso kusaipitsa, ndi zina zambiri, ndikulowetsa mabatire pang'onopang'ono, ndipo ali ndi mwayi wamsika waukulu.
Ma supercapacitor amapangidwa makamaka ndi maelekitirodi, otolera apano, olekanitsa pakati pa maelekitirodi ndi ma electrolyte.Pakati pawo, zinthu za electrode ndi chimodzi mwazinthu zazikulu zomwe zimakhudza ndikudziwitsa momwe ma supercapacitors amagwirira ntchito.Zida zama elekitirodi zama supercapacitors zimaphatikizira zida zopangira ma elekitirodi a kaboni, zida zachitsulo za oxide electrode, ndi zida zopangira ma polymer electrode.Pali magulu ambiri azinthu zama elekitirodi opangidwa ndi kaboni, zida zachitsulo za oxide electrode, ndi zida zopangira ma polymer electrode.
Pakati pa zida za electrode za supercapacitor, zida zopangira kaboni ndi kafukufuku wakale kwambiri komanso ukadaulo wokhwima.Zomwe zimaphunziridwa kwambiri ndi ma elekitirodi a carbon ndi: activated carbon, activated carbon fiber, ndi carbon aerogel.
1. Activated carbon ndi carbon electrode material yomwe imagwiritsidwa ntchito mu supercapacitors pachiyambi.Ubwino wake wamachitidwe ndi: malo akuluakulu enieni;kupanga pore kapangidwe;mkulu mankhwala bata;njira yosavuta;mtengo wotsika, woyenera kupanga zazikulu.
2. activated carbon fibre: Ndi chinthu chogwirizana ndi chilengedwe chomwe chimakhala ndi mphamvu yotsatsa kuposa carbon activated.Nsalu yapamwamba yopangidwa ndi mpweya wa carbon fiber yakhala ikugwiritsidwa ntchito bwino ngati malonda a electrode.
3.Carbon aerogel: Ndi makina a kaboni olumikizidwa ndi intaneti okhala ndi mawonekedwe olumikizana.Ili ndi porosity, conductivity yabwino, malo akuluakulu, porosity yayikulu, kugawa kwakukulu kwa pore, ndipo imatha kuyendetsa magetsi.Ndizinthu zabwino zama elekitirodi pokonzekera ma capacitors amagetsi apawiri.
JYH HSU(JEC) Electronics Ltd (kapena Dongguan Zhixu Electronic Co., Ltd.) yakhala ikuchita nawo gawo lamagetsi kwazaka zambiri, ndipo akatswiri athu aukadaulo atha kukuthandizani kuthana ndi mavuto okhudzana nawo.Mukamagula ma varistors, muyenera kudziwa ngati zinthuzo zimachokera kwa opanga nthawi zonse.Wopanga varistor wabwino amatha kuchepetsa mavuto ambiri osafunikira.
