I-ultracapacitor ethengiswa ngobuninzi

Umfanekiso oPhambili we-ultracapacitor ethengiswa ngobuninzi

Inkcazo emfutshane:

I-supercapacitor, ekwaziwa ngokuba yi-ultracapacitor okanye i-Electrical Doule-Layer Capacitor、I-capacitor yegolide、I-farad capacitor. I-capacitor igcina amandla ngokusebenzisa itshaja engashukumiyo ngokuchaseneyo ne-electrochemical reaction. Ukusebenzisa umahluko we-voltage kwiiplate ezilungileyo nezingalunganga kuyayitshaja i-capacitor.

Yinto ye-electrochemical, kodwa ayitshintshi iimpembelelo zeekhemikhali kwinkqubo yokugcina amandla, nto leyo enokuthi iguqulwe, yiyo loo nto ii-supercapacitors zinokutshajwa ngokuphindaphindiweyo kwaye zikhutshwe ngamakhulu amawaka amaxesha.

Iziqwenga ze-super capacitor zinokubonwa njengeepleyiti ezimbini ze-electrode ezingenayo i-reactive porous, kwipleyiti, ipleyiti yombane, i-positive itsala ii-ions ezingalunganga kwi-electrolyte, ipleyiti engalunganga itsala ii-ions ezintle, zenze umaleko wesibini wokugcina i-capacitive. Ii-ions ezilungileyo ezahlulweyo zikufutshane nepleyiti engalunganga, kwaye ii-ions ezingalunganga zikufutshane nepleyiti engalunganga.

Amandla okugcina

Kutheni intle kakhulu?

IiSupercapacitors zigcina amandla kwitshaja ehlukanisiweyo. Okukhona indawo esetyenziselwa ukugcina itshaja inkulu kwaye itshaja ehlukanisiweyo ixinene, kokukhona i-capacitance inkulu.
Indawo ye-capacitor yendabuko yindawo ethe tyaba ye-conductor. Ukuze kufumaneke umthamo omkhulu, izinto ze-conductor zisongwa zibe zinde kakhulu, ngamanye amaxesha zibe nesakhiwo esikhethekileyo sokwandisa indawo yayo yomphezulu. I-capacitor yendabuko yahlula ii-electrodes zayo ezimbini ngezinto zokukhusela, ngokuqhelekileyo ifilimu yeplastiki, iphepha, njl. Ezi zinto zihlala zifuneka ukuba zibe ncinci kangangoko.

Indawo ye-supercapacitor isekelwe kwizinto zekhabhoni ezinemibhobho, ezinemibhobho evumela indawo ukuya kuthi ga kwi-2000m2/g, kunye neendlela ezithile ezikhokelela kwindawo enkulu yomphezulu. Umgama owahlulwa yitshaja ye-supercapacitor umiselwa bubungakanani bee-ion ze-electrolyte ezitsalwa yi-electrode etshajiweyo. Umgama (<10 Å) Kwaye izinto zefilimu ye-capacitor yendabuko zinokufikelela kumgama omncinci. Umgama (<10 Å) mncinci kunowezinto zefilimu ye-capacitor yendabuko.
Le ndawo inkulu yomphezulu kunye nemigama emincinci kakhulu yokwahlulahlula itshaja yenza ii-supercapacitors zibe nomthamo ophezulu ngokumangalisayo wokungashukumi xa kuthelekiswa nee-capacitors eziqhelekileyo.

Xa kuthelekiswa nebhetri, yeyiphi engcono?

Ngokungafaniyo neebhetri, ii-supercapacitors zinokuba ngcono kuneebhetri kwezinye iinkqubo. Ngamanye amaxesha ukudibanisa ezi zimbini, ukudibanisa iimpawu zamandla ze-capacitor kunye nokugcinwa kwamandla aphezulu kwebhetri, yindlela engcono.
I-supercapacitor inokutshajwa kuyo nayiphi na i-potential ngaphakathi koluhlu lwayo lwe-voltage olulinganisiweyo kwaye inokukhululwa ngokupheleleyo. Iibhetri, kwelinye icala, zithintelwa ziimpendulo zazo zeekhemikhali kwaye zisebenza kuluhlu oluncinci lwe-voltage, olunokubangela umonakalo ngokwesondo ukuba lukhutshwa kakhulu.
Imeko yokutshaja (i-SOC) kunye ne-voltage ye-supercapacitor zenza umsebenzi olula, ngelixa imeko yokutshaja yebhetri ibandakanya iintlobo ngeentlobo zokuguqulwa okunzima.
I-supercapacitor inokugcina amandla amaninzi kune-capacitor eqhelekileyo yobukhulu bayo. Kwezinye iinkqubo apho amandla amisela ubungakanani bezixhobo zokugcina amandla, ii-supercapacitors zisisombululo esingcono.
I-supercapacitor inokudlulisa amandla ngokuphindaphindiweyo ngaphandle kwemiphumo emibi, ngelixa ubomi bebhetri bungakhuseleki ukuba idlulisela amandla aphezulu ngokuphindaphindiweyo.
Ii-Ultracapacitors zinokutshajwa ngokukhawuleza, ngelixa iibhetri zinokonakala ukuba zitshajwa ngokukhawuleza.
Ii-Supercapacitors zinokuphinda zisetyenziswe izihlandlo ezingamakhulu amawaka, ngelixa ubomi bebhetri buzizihlandlo ezingamakhulu ambalwa kuphela.
