I-Graphite njengo-Electrode: Umhlahlandlela Ophelele

Lo mbhalo uhlola iqhaza elihlanganisiwe le-graphite njengezinto ze-electrode, emboza izakhiwo zayo, izinhlelo zokusebenza, izinzuzo, kanye nemikhawulo. Sisebenzisa ezinhlotsheni ezahlukahlukene ze-lectrodes ye-graphite, izinqubo zazo zokukhiqiza, kanye nokusebenza kwazo ezinhlelweni ezahlukahlukene ze-electrochemical. Funda ukuthi izici ezihlukile ze-graphite zikwenza kanjani kube yingxenye ebalulekile ebuhlungwini bezobuchwepheshe.

Ukuqonda izakhiwo zika-Graphite ze-Electrode Application

Ukusebenza okukhethekile kukagesi

Isakhiwo esinqunyelwe se-graphite sivumela ukuqina kukagesi okuhle kakhulu, okwenza kube kuhle ukudlulisa ama-elektroni ezinhlanganweni ze-electrochemical. Lokhu kuqhutshwa okuphezulu kubalulekile ekusebenzeni kahle kwamabhethri, amaseli kaphethiloli, nakwamanye amasistimu asuselwa ku-electrode. Ukuqhutshwa okuthile kungahluka ngokuya ngohlobo nobumsulwa be-graphite esetshenzisiwe. Isibonelo, i-prographite ethambekele kakhulu ye-pyrolytic (hopg) eqondiswe kakhulu (i-hopg) ekhombisa ngokungemthetho okuphezulu ngendiza eyisisekelo.

Ukuqina kwamakhemikhali nokuvunza

Kumahlelo amaningi, ukuqina kwamakhemikhali I-Graphite njengo-Electrode izinto ezibonakalayo zibaluleke kakhulu. I-inertness yayo ivimbela ukusabela kwamakhemikhali okungafuneki nge-electrolyte, ukuqinisekisa isikhathi eside kanye nokwethenjwa kwensiza ye-electrochemical. Kodwa-ke, kubalulekile ukuqaphela ukuthi ukuqina kwe-graphite kungathintwa yizinto ezinjengokushisa kanye nokwakheka kwamakhemikhali kwe-electrolyte. Amanye amabanga we-graphite akhethekile aphathwa ukuthuthukisa ukumelana nawo kwi-oxidation kanye nokugqwala.

Indawo ephezulu yendawo

Indawo ephezulu yendawo efiselekayo ithandeka kuzinhlelo zokusebenza eziningi ze-elektrode njengoba ivumela ukuthintana okukhulu phakathi kwezinto ze-electrode ne-electrodete, ngcono kinetics yokuphendula kanye nokusebenza okuphelele. Izinhlobo ezahlukahlukene zegrafu, njenge-graphite enwetshiwe, nikeza izindawo eziphakeme kakhulu zendawo uma kuqhathaniswa negrafu ejwayelekile, kuthuthukisa ukufaneleka kwazo izinhlelo zokusebenza ezifana ne-supercapacitors.

Izinhlobo ze-graphite electrodes

Izinhlobo ezahlukahlukene zama-graphite zisetshenziswa njenge-electrodes, ngalinye lihambisana nezidingo ezithile:

Ama-electrodes wemvelo wemvelo

Kuthathwe kuma-graphits we-graphits wemvelo avela ngokwemvelo, lawa ma-elektrodi anikela ngesisombululo esisebenza ngempumelelo kwezicelo eziningi. Kodwa-ke, izakhiwo zabo zingahluka ngokuya ngemithombo kanye nezindlela zokucubungula. Zivame ukusetshenziswa kuzinhlelo zokusebenza lapho ubumsulwa obuphezulu bungagxeki.

Zokwenziwa kwe-graphite electrodes

Ama-electrodete we-graphite akhiqizwa ngezinqubo zokushisa aphezulu futhi anikeze amandla amakhulu phezu kwezindawo zawo, njengobumsulwa, ukwakheka kwe-crystal, kanye ne-porusity. Lokhu kuvumela ukwenza ngokwezifiso ama-electrodes ahlangabezane nezidingo ezithile zokusebenza. Zivame ukuncamela izinhlelo zokusebenza eziphezulu ezifana namabhethri e-lithium-ion.

OLUNYE OKWENGEZIWE BRAPTITE ELFODES

Izinhlobo eziningana ezikhethekile ze-graphite zisetshenziselwa izinhlelo ezithile, kufaka phakathi:

• I-prographicte eqondiswe kakhulu ye-prolytictic (hopg): Yaziwa ngokusebenza kwayo okuyingqayizivele nesakhiwo se-crystalline.
• I-Graphite Enwetshiwe: Unesindawo esiphakeme kakhulu ngenxa yesakhiwo sayo esixogani.
• I-GraphiPE enhle: Ifaka isakhiwo se-porous kakhulu sokusebenza kwe-electrochemical ethuthukisiwe.

Izicelo ze-graphite electrodes

Isimo esiguquguqukayo se I-Graphite njengo-Electrode Indwangu yenza ukuba kubaluleke kakhulu ebuhlungwini bezobuchwepheshe:

Ngekhwalithi ephezulu I-Graphite njengo-Electrode izinto zokwakha, cabanga ngokuhlola iminikelo evela Hebei Yaofa Carbon Co, Ltd., umphakeli oholayo wemikhiqizo yekhabhoni. Banikeza uhla lwemikhiqizo ye-graphite eyenzelwe izinhlelo ezahlukahlukene.

Izinselelo Nezitayela Ezizayo

Naphezu kokusetshenziswa kwayo okusakazekile, izinselelo zihlala zisebenzisa I-Graphite njengo-Electrode. Lokhu kufaka phakathi ukwenza kahle ukusebenza kwayo ezimweni ezimbi kakhulu, kuthuthukisa impilo yayo yomjikelezo, kanye nokuhlola amanye amafomu ukuthuthukisa izakhiwo zalo ngokuqhubekayo. Ucwaningo oluqhubekayo lugxile ekuthuthukiseni izinto ze-electrode ezisuselwa ku-electrode ezisuselwa kwe-electrochemical izakhiwo ukufeza izimfuno zobuchwepheshe obusafufusa, njengamabhethri wesizukulwane esilandelayo kanye nezinhlelo zokugcina amandla.

¹ Idatha kwizakhiwo ezithile ze-graphite ingatholakala kwimininingwane ehlukahlukene yesayensi yezinto ezibonakalayo kanye namawebhusayithi abakhiqizi. Sicela ubheke imithombo edumile ukuze uthole imininingwane enemininingwane.
