Ama-Supercapacitor abizwa ngokuthi ama-electric double layer capacitor kanye nama-farad capacitor, athuthukiswe kusukela ngawo-1980.Ngokungafani nama-capacitor wendabuko, ama-supercapacitor awuhlobo olusha lwama-capacitor e-electrochemical, aphakathi kwama-capacitor namabhethri, futhi awatholi ukusabela kwamakhemikhali phakathi nenqubo yokugcina amandla.
Ama-Supercapacitor anezici zejubane lokushaja ngokushesha, izikhathi ezingamakhulu ezinkulungwane zokushaja nokukhipha, ukugcinwa kwamandla, ukuvikelwa kwemvelo nokungangcoli, njll., futhi kancane kancane ashintsha amabhethri, futhi abe namandla amakhulu emakethe.
Ama-Supercapacitor ikakhulukazi akhiwa ama-electrode, abaqoqi bamanje, izihlukanisi phakathi kwama-electrode nama-electrolyte.Phakathi kwazo, izinto ze-electrode zingenye yezinto ezibalulekile ezithinta futhi ezinquma ukusebenza kwama-supercapacitor.Izinto ze-electrode zama-supercapacitors zifaka izinto ze-electrode esekwe ku-carbon, izinto ze-metal oxide electrode, nezinto ezisetshenziswayo ze-polymer electrode.Kunezigaba eziningi zezinto ze-electrode ezisekelwe ku-carbon, izinto ze-metal oxide electrode, nezinto zokwenziwa kwe-polymer electrode.
Phakathi kwezinto zokwenziwa kwe-electrode ye-supercapacitor, izinto ezisuselwa kukhabhoni ziwucwaningo lwakuqala nobuchwepheshe obuvuthiwe.Izinto ezifundwa kakhulu ku-carbon-based electrode yilezi: i-activated carbon, i-activated carbon fiber, ne-carbon aerogel.
1. Ikhabhoni ecushiwe yi-carbon electrode material esetshenziswa kuma-supercapacitor ekuqaleni.Izinzuzo zayo zokusebenza yilezi: indawo enkulu ethize;ukwakheka kwezimbotshana ezithuthukisiwe;ukuzinza okuphezulu kwamakhemikhali;inqubo elula;izindleko eziphansi, ezifanele ukukhiqizwa kwezinga elikhulu.
2. I-activated carbon fibre: Kuyinto evumelana nemvelo enomsebenzi wokukhangisa onamandla kunekhabhoni ecushiwe.Indwangu ephezulu ye-carbon fiber eyenziwe yasebenza kuyo isetshenziswe ngempumelelo njengento yokuhweba ye-electrode.
3.I-Carbon aerogel: Iwumthombo wekhabhoni onenethiwekhi enesakhiwo esixhumene.Ine-porosity, i-conductivity enhle, indawo enkulu, i-porosity ephezulu, ukusabalalisa usayizi wezimbotshana ezibanzi, futhi ingaqhuba ugesi.Kuyinto efanelekile ye-electrode yokulungiselela ama-capacitor kagesi angama-double layer.
I-JYH HSU(JEC) Electronics Ltd (noma i-Dongguan Zhixu Electronic Co., Ltd.) ibambe iqhaza embonini yezingxenye zikagesi iminyaka eminingi, futhi onjiniyela bethu bezobuchwepheshe bangakusiza ukuxazulula izinkinga ezihlobene.Lapho uthenga ama-varistors, udinga ukuthola ukuthi imikhiqizo ivela kubakhiqizi abajwayelekile.Umkhiqizi omuhle we-varistor anganciphisa izinkinga eziningi ezingadingekile.
