I-Capacitor iyingxenye egcina ishaja kagesi.Umgomo wokugcina amandla we-general capacitor kanye ne-ultra capacitor (EDLC) uyafana, kokubili ukushaja kwesitolo ngendlela yenkundla ye-electrostatic, kodwa i-super capacitor ifaneleka kakhulu ukukhululwa okusheshayo nokugcinwa kwamandla, ikakhulukazi ekulawuleni amandla okunemba kanye namadivayisi okulayisha ngokushesha. .
Ake sixoxe ngomehluko omkhulu phakathi kwama-capacitor avamile nama-super capacitor ngezansi.
| Izinto zokuqhathanisa | I-Capacitor evamile | I-Supercapacitor |
| Uhlolojikelele | I-conventional capacitor iyi-static charge storage dielectric, engase ibe neshaja yaphakade futhi isetshenziswa kabanzi.Iyingxenye ye-elekthronikhi ebaluleke kakhulu emkhakheni wamandla kagesi. | I-Supercapacitor, eyaziwa nangokuthi i-electrochemical capacitor, i-double layer capacitor, i-golden capacitor, i-Faraday capacitor, iyingxenye ye-electrochemical eyakhiwa kusukela ngeminyaka yawo-1970 nawo-1980 ukugcina amandla ngokuhlukanisa i-electrolyte. |
| Ukwakha | I-capacitor evamile iqukethe amakhondatha ensimbi amabili (ama-electrodes) asondelene ngokuhambisana kodwa angaxhumani, ane-dielectric evikelayo phakathi. | I-supercapacitor iqukethe i-electrode, i-electrolyte (equkethe usawoti we-electrolyte), kanye nesihlukanisi (ukuvimbela ukuthintana phakathi kwama-electrode amahle nabi). Ama-electrode ambozwe ngekhabhoni ecushiwe, enezimbotshana ezincane ebusweni bayo ukuze andise indawo engaphezulu yama-electrode futhi yonge ugesi owengeziwe. |
| Izinto ze-Dielectric | I-aluminium oxide, amafilimu e-polymer noma izitsha zobumba zisetshenziswa njengama-dielectrics phakathi kwama-electrode kuma-capacitor. | I-supercapacitor ayinayo i-dielectric.Esikhundleni salokho, isebenzisa ungqimba olukabili lukagesi olwakhiwe okuqinile (i-electrode) noketshezi (i-electrolyte) endaweni esibonakalayo esikhundleni se-dielectric. |
| Isimiso sokusebenza | Isimiso sokusebenza se-capacitor yukuthi ukushaja kuzohanjiswa ngamandla emkhakheni kagesi, lapho kukhona i-dielectric phakathi kwabaqhubi, ivimbela ukunyakaza kokushaja futhi yenza ukushaja kuqoqwe kumqhubi, okuholela ekuqoqweni kwesitoreji sokushaja. . | Ama-Supercapacitor, ngakolunye uhlangothi, azuza isitoreji samandla esinezingqimba ezimbili ngokuhlukanisa i-electrolyte kanye nezindleko ze-redox pseudo-capacitive. Inqubo yokugcina amandla yama-supercapacitor ibuyiselwa emuva ngaphandle kokusabela kwamakhemikhali, futhi ngaleyo ndlela ingashajwa ngokuphindaphindiwe futhi ikhishwe izikhathi ezingamakhulu ezinkulungwane. |
| Amandla | Umthamo omncane. Umthamo we-capacitance jikelele usukela ku-pF embalwa ukuya ezinkulungwaneni ezimbalwa ze-μF. | Umthamo omkhulu. Umthamo we-supercapacitor mkhulu kangangokuthi ungasetshenziswa njengebhethri.Umthamo we-supercapacitor uncike ebangeni eliphakathi kwama-electrode nendawo engaphezulu yama-electrode.Ngakho-ke, ama-electrode ahlanganiswe nekhabhoni ecushiwe ukuze kwandiswe indawo engaphezulu ukuze kuzuzwe umthamo omkhulu. |
| Ukuminyana kwamandla | Phansi | Phezulu |
| Amandla athile | <0.1 Wh/kg | 1-10 Wh/kg |
| Amandla athile | 100,000+ Wh/kg | 10,000+ Wh/kg |
| Isikhathi sokushaja / sokukhipha | Izikhathi zokushaja nokukhipha ama-capacitor avamile ngokuvamile ziyimizuzwana engu-103-106. | Ama-Ultracapacitor angaletha ukushaja ngokushesha kunamabhethri, ngokushesha njengemizuzwana eyi-10, futhi agcine ukushaja okuningi ngevolumu yeyunithi kunama-capacitor ajwayelekile.Yingakho kubhekwa phakathi kwamabhethri nama-electrolytic capacitors. |
| Impilo yomjikelezo wokushaja/wokukhipha | Kafushane | Mude (ngokuvamile i-100,000 +, imijikelezo efika esigidini esi-1, ngaphezu kweminyaka eyi-10 yokufaka isicelo) |
| Ukushaja/ukukhulula ukusebenza kahle | >95% | 85%-98% |
| Izinga lokushisa lokusebenza | -20 kuya ku-70 ℃ | -40 kuya ku-70 ℃ (Izici ezingcono zokushisa eziphansi kakhulu kanye nebanga lokushisa elibanzi) |
| I-voltage elinganiselwe | Phezulu | Phansi (ngokuvamile i-2.5V) |
| Izindleko | Phansi | Phezulu |
| Inzuzo | Ukulahlekelwa okuncane Ukuminyana okuphezulu kokuhlanganisa Ukulawula amandla asebenzayo futhi asebenzayo | Impilo ende Umthamo ophezulu kakhulu Ukushaja okusheshayo nesikhathi sokukhipha Ukulayisha okuphezulu kwamanje Ibanga lokushisa elibanzi lokusebenza |
| Isicelo | ▶Okukhipha amandla abushelelezi; ▶Power Factor Correction (PFC); ▶ Izihlungi zefrequency, pass high, low pass filters; ▶Ukuhlanganisa nokuhlukanisa amasignali; ▶ Iziqalisi zezimoto; ▶Amabhafa (izivikeli zokuhlinza nezihlungi zomsindo); ▶ Ama-oscillator. | ▶ Izimoto zamandla amasha, ujantshi wesitimela nezinye izinhlelo zokuhamba; ▶ Ukunikezwa kwamandla okungaphazamiseki (UPS), esikhundleni samabhange e-electrolytic capacitor; ▶ Ukunikezwa kwamandla omakhalekhukhwini, amakhompyutha aphathekayo, amadivaysi aphathwayo, njll.; ▶ Izikulufu zikagesi ezishajwa kabusha ezingashajwa ngokugcwele ngemizuzu; ▶Izinhlelo zokukhanyisa eziphuthumayo kanye namadivayisi kagesi anamandla amakhulu; ▶ Ama-IC, i-RAM, i-CMOS, amawashi namakhompyutha amancane, njll. |
Uma unokuthile ongakwengeza noma eminye imininingwane, sicela ukhululeke ukuxoxa nathi.
