Dab tsi yog ib qholub supercapacitor 

Cov supercapacitors raug muab faib ua ob txheej hluav taws xob capacitors thiab pseudocapacitors los ntawm lub tshuab khaws cia lub zog. Nws yog ib hom khoom siv khaws cia lub zog tshiab, uas muaj cov yam ntxwv ntawm lub zog ceev ceev, lub sijhawm them luv luv, lub neej ua haujlwm ntev, cov yam ntxwv kub zoo, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig ntsuab. Supercapacitors muaj ntau yam.

Cov supercapacitors puas tuaj yeem yog roj teeb

Cov supercapacitors tuaj yeem hloov cov roj teeb, uas kuj yog ib qho kev taw qhia yav tom ntej.

Cov Supercapacitors, tseem hu ua ob txheej capacitors, electrochemical capacitors, kub capacitors, thiab Farrah capacitors, khaws lub zog los ntawm polarizing electrolytes. Nws yog ib qho electrochemical element, tab sis hauv nws cov txheej txheem khaws lub zog tsis tshwm sim tshuaj lom neeg, cov txheej txheem khaws lub zog no yog reversible, tab sis kuj vim tias qhov supercapacitor no tuaj yeem rov them thiab tso tawm ntau pua txhiab zaus. Supercapacitors tuaj yeem xav txog ob lub phaj electrode tsis-reactive porous uas dai rau hauv electrolyte, them rau ntawm lub phaj, lub phaj zoo nyiam cov ions tsis zoo hauv electrolyte, lub phaj tsis zoo nyiam cov ions zoo, qhov tseeb tsim ob txheej cia capacitive, cov ions zoo raug sib cais ze ntawm lub phaj tsis zoo, thiab cov ions tsis zoo nyob ze ntawm lub phaj zoo.

Supercapacitor yog ib hom capacitor tshiab raws li txoj kev xav ntawm ob txheej interfacial uas tau hais los ntawm tus kws kho mob German Helmholtz. Raws li peb txhua tus paub, qhov chaw ntawm cov hlau electrode ntxig rau hauv cov kua electrolyte yuav tshwm sim ntawm ob sab ntawm cov kua nrog cov cim sib txawv ntawm cov nqi ntau dhau, yog li qhov sib txawv ntawm cov theem yuav raug tsim. Tom qab ntawd, yog tias ob lub electrodes raug ntxig rau hauv electrolyte tib lub sijhawm, thiab qhov hluav taws xob tsawg dua qhov hluav taws xob decomposition ntawm cov kua electrolyte raug siv ntawm lawv, ces cov ions zoo thiab tsis zoo hauv electrolyte yuav txav mus sai sai rau cov ncej nyob rau hauv qhov kev ua ntawm lub teb hluav taws xob, thiab feem ntau tsim ib txheej them ceev ceev ntawm qhov chaw ntawm ob lub electrodes sab saud, uas yog, ob txheej hluav taws xob.

Cov txheej hluav taws xob ob txheej uas nws tsim zoo ib yam li cov nqi polarized uas tsim los ntawm dielectric hauv lub capacitor ib txwm muaj nyob rau hauv qhov kev ua ntawm lub teb hluav taws xob, ua rau muaj qhov cuam tshuam capacitance. Cov txheej hluav taws xob ob txheej nruj zoo ib yam li lub capacitor tiaj tus, tab sis vim tias qhov sib nrug ntawm cov txheej them nruj me dua qhov deb ntawm cov txheej them ntawm lub capacitor ib txwm muaj, nws muaj peev xwm loj dua li lub capacitor ib txwm muaj.

Qhov tsis kam sab hauv ntawm lub capacitor ob txheej loj dua li ntawm lub aluminium electrolytic capacitor, yog li nws tuaj yeem them ncaj qha yam tsis muaj kev tiv thaiv load. Yog tias muaj qhov them overvoltage, lub capacitor ob txheej yuav qhib lub voj voog yam tsis ua rau lub cuab yeej puas tsuaj, uas txawv ntawm qhov tawg overvoltage ntawm lub aluminium electrolytic capacitor. Tib lub sijhawm, piv nrog lub roj teeb rechargeable, lub capacitor ob txheej hluav taws xob tuaj yeem them tsis muaj kev txwv, thiab tus lej ntawm kev them tuaj yeem ncav cuag ntau dua 10 ^ 6 zaug, yog li lub capacitor ob txheej hluav taws xob tsis yog tsuas yog muaj cov yam ntxwv ntawm lub capacitor, tab sis kuj muaj cov yam ntxwv ntawm lub roj teeb, thiab yog ib qho khoom tshwj xeeb tshiab ntawm lub roj teeb thiab lub capacitor.
