I-Supercapacitor: uhlobo olusha lwesici sokugcina amandla e-electrochemical, esakhiwe kusukela ngawo-1970 kuya ku-1980, esakhiwe ngama-electrode, ama-electrolyte, ama-diaphragms, abaqoqi bamanje, njll., ngesivinini sokugcina amandla asheshayo kanye nokugcinwa kwamandla amakhulu.I-capacitance ye-supercapacitor incike esikhaleni se-electrode kanye nendawo ye-electrode surface.Ukunciphisa isikhala se-electrode ye-supercapacitor nokwandisa indawo ye-electrode kuzokwandisa amandla e-supercapacitor.Ukugcinwa kwayo kwamandla kusekelwe esimisweni sokugcinwa kwe-electrostatic.I-carbon electrode iyi-electrochemically futhi izinzile ngokwesakhiwo, futhi ingashajwa ngokuphindaphindiwe izikhathi ezingamakhulu ezinkulungwane, ngakho ama-supercapacitor angasetshenziswa isikhathi eside kunamabhethri.
Kodwa-ke, ama-supercapacitor nawo angaba nezinkinga ngesikhathi sokusebenza, njengokuguga.Ukuguga kwama-supercapacitor kushintsha ama-electrode, ama-electrolyte nezinye izakhi ze-supercapacitor ezivela ezintweni ezibonakalayo namakhemikhali, okuholela ekugugeni kwama-supercapacitor, okubangela ukuwohloka kokusebenza, futhi lokhu konakala akunakuhlehliswa.
Ukuguga kwama-supercapacitor:
1. Igobolondo Elilimele
Lapho ama-supercapacitor esebenza endaweni enomswakama isikhathi eside, okungaholela kalula ekuwohlokeni kokusebenza futhi kufinyeze kakhulu isikhathi sokusebenza.Umswakama emoyeni ungena ku-capacitor futhi uqoqa, futhi ukucindezela kwangaphakathi kwe-supercapacitor kwakha.Ezimweni ezimbi kakhulu, isakhiwo se-supercapacitor casing siyabhujiswa.
2. Ukuwohloka kwe-Electrode
Isizathu esiyinhloko sokuwohloka kokusebenza kwama-supercapacitor ukuwohloka kwama-electrode e-carbon activated porous.Ngakolunye uhlangothi, ukuwohloka kwama-electrode e-supercapacitor kubangele ukuthi isakhiwo sekhabhoni esicushiwe sicekelwe phansi ngenxa ye-oxidation engaphezulu.Ngakolunye uhlangothi, inqubo yokuguga iphinde yabangela ukufakwa kokungcola endaweni ye-electrode, okubangele ukuthi izimbotshana eziningi zivaleke.
3. Ukubola kwe-Electrolyte
Ukubola okungenakuhlehliswa kwe-electrolyte, okunciphisa kakhulu isikhathi sokusebenza sama-supercapacitor, kungenye imbangela yokuguga.Ukunciphisa i-oxidation ye-electrolyte ukukhiqiza amagesi afana ne-CO2 noma i-H2 kuholela ekwandeni kokucindezela kwangaphakathi kwe-supercapacitor, futhi ukungcola okukhiqizwa ukubola kwayo kunciphisa ukusebenza kwe-supercapacitor, kwandise i-impedance, futhi kubangele ubuso be-supercapacitor. i-activated carbon electrode izokonakala.
4. Ukuzikhipha
Ukuvuza kwamanje okukhiqizwa yi-self-discharge ye-supercapacitor nakho kunciphisa kakhulu isikhathi sokusebenza nokusebenza kwe-supercapacitor.I-current ikhiqizwa amaqembu asebenzayo e-oxidized, futhi amaqembu asebenzayo ngokwawo akhiqizwa ukusabela kwe-electrochemical endaweni ye-electrode, okuzophinde kusheshise ukuguga kwe-supercapacitor.
Okungenhla kukhona ukubonakaliswa okuningana kokuguga kwama-supercapacitor.Uma ukuguga kwe-capacitor kwenzeka ngesikhathi sokusetshenziswa, kuyadingeka ukufaka esikhundleni se-capacitor ngesikhathi.
