Supercapacitor: rudzi rutsva rwemagetsi emagetsi ekuchengetedza simba, akagadzirwa kubva kuma1970 kusvika kuma1980s, akaumbwa nemagetsi, electrolytes, diaphragms, vaunganidzi vemazuva ano, nezvimwewo, inokurumidza kukurumidza kuchengetedza simba uye yakakura kuchengetedza simba.Iyo capacitance ye supercapacitor inotsamira pane electrode spacing uye electrode pamusoro nzvimbo.Kuderedza nzvimbo ye electrode ye supercapacitor uye kuwedzera nzvimbo ye electrode ichawedzera capacitance ye supercapacitor.Simba rayo rekuchengetedza rakavakirwa pamusimboti we electrostatic kuchengetedza.Iyo kabhoni electrode ndeye electrochemically uye yakagadzikana, uye inogona kudzokororwa kuchajwa kwemazana ezviuru zvenguva, saka supercapacitor inogona kushandiswa kwenguva yakareba kupfuura mabhatiri.
Zvisinei, supercapacitors inogonawo kuva nematambudziko panguva yekushanda, zvakadai sekukwegura.Kuchembera kwema supercapacitors kunoshandura ma electrode, electrolytes uye zvimwe zvikamu zve supercapacitor kubva kune yemuviri uye makemikari zvimiro, zvichikonzera kuchembera kwema supercapacitors, zvichikonzera kuderera kwekuita, uye kuparara uku hakugone kudzoka.
Kuchembera kwema supercapacitors:
1. Shell Yakakuvadzwa
Apo ma-supercapacitors anoshanda munzvimbo ine hunyoro kwenguva yakareba, izvo zvinogona kutungamirira nyore kuparara kwekuita uye kupfupisa zvikuru nguva yekushanda.Unyoro huri mumhepo hunopinda mukati me capacitor uye hunounganidza, uye kumanikidzwa kwemukati kwe supercapacitor kunovaka.Muzviitiko zvakanyanyisa, chimiro che supercapacitor casing chinoparadzwa.
2. Electrode Deterioration
Chikonzero chikuru chekudzikira kwekuita kwe supercapacitors ndiko kudzikira kweporous activated carbon electrodes.Kune rimwe divi, kushata kwema electrode e supercapacitor kwakakonzera iyo activated kabhoni chimiro kuparadzwa zvishoma nekuda kweiyo oxidation yepasi.Kune rumwe rutivi, kuchembera kwakakonzerawo kuiswa kwetsvina panzvimbo ye electrode, zvichiita kuti mapores mazhinji avharwe.
3. Kuparara kweElectrolyte
Kuparara kusingagadziriswi kwe electrolyte, iyo inopfupisa zvikuru nguva yekushanda ye supercapacitors, chimwe chikonzero chekukwegura.Iyo oxidation-kuderedzwa kwe electrolyte kugadzira magasi akadai se CO2 kana H2 kunotungamirira kuwedzera kwemukati kumanikidzwa kwe supercapacitor, uye tsvina inogadzirwa nekuparara kwayo inoderedza kushanda kweiyo supercapacitor, kuwedzera impedance, uye kukonzera pamusoro iyo activated carbon electrode kuti iparare.
4. Kuzviburitsa
Iyo yekudonha ikozvino inogadzirwa nekuzviburitsa kweiyo supercapacitor zvakare inoderedza zvakanyanya nguva yekushanda uye kuita kweiyo supercapacitor.Iyo yazvino inogadzirwa neiyo oxidized inoshanda mapoka, uye mapoka anoshanda iwo pachawo anogadzirwa ne electrochemical reactions pane electrode surface, iyo ichaitawo kukurumidza kuchembera kweiyo supercapacitor.
Izvo zviri pamusoro apa zvakati wandei kuratidzwa kwekuchembera kwema supercapacitors.Kana kuchembera kwe capacitor kuchiitika panguva yekushandiswa, zvakakosha kutsiva capacitor munguva.
Isu tiri JYH HSU(JEC) Electronics Ltd (kana Dongguan Zhixu Electronic Co., Ltd.), inogadzira zvinhu zvemagetsi.Tikugashirei kushanyira webhusaiti yedu yepamutemo kuti udzidze zvakawanda nezvekambani yedu kana kutibvunza kushandira pamwe kwebhizinesi.
