Ukuqonda iipropathi zomzobo wemifanekiso ye-electrode

Ukuqhekeka kombane okhethekileyo

Ulwakhiwo lomfanekiso wegrafu luvumela ukwenzeka kombane okuphezulu, kuyenza ilungele ukudlulisela ii-elektroni kwiinkqubo ze-elektroniki. Le ndlela yokuphumelela ibalulekile ekusebenzeni kakuhle kwiibhetri, iiseli zepetroli, kunye nezinye iinkqubo ezisekwe e-Electrode. Ukucokiseka okuthile kunokwahluka ngokuxhomekeke kuhlobo kunye nokucoceka kwegrafu esetyenzisiweyo. Umzekelo, i-piyrolytite ye-piyrolytic ye-piyrolytic (i-HOPG) ibonakalisa ukwenziwa okuphezulu okuphezulu kwindiza ye-bassal.

Uzinzo lwekhemikhali kunye ne-interture

Kwizicelo ezininzi, uzinzo lwekhemikhali igrafu njenge-electrode Izinto ezibonakalayo ziyinto entle. Ukungena kwayo kuthintela ukuphendula kweekhemikhali okungafunekiyo kunye ne-electrolyte, kuqinisekisa ubumnene kunye nokuthembeka kwesixhobo se-electrochemical. Nangona kunjalo, kubalulekile ukuba uqaphele ukuba uzinzo lwegrafili unokuchaphazeleka ngezinto ezifana nobushushu kunye nokwenziwa kwamachiza ze-electrolyte. Amanye amaBanga aKhethekileyo amaGcisa akhutshwa ukuze aphucule ukuxhathisa i-oxidotion kunye neyosu.

Indawo ephezulu

Indawo ephezulu yomhlaba inqweneleka kwizicelo ezininzi ze-electrode njengoko ivumela ukunxibelelana kakhulu phakathi kwempahla ye-electrode kunye ne-electrolyte, ukuphucula i-kinetics kunye ne-kinetics uphendula. Iifom ezahlukeneyo zegrafu, ezinjengegrafu eyandisiweyo, zinike iindawo eziphezulu zomphezulu ezithelekiswa negrafu yesiqhelo, ekhuthaza ukufaneleka kwabo kwizicelo ezithile ezifana nezixhobo ze-supercacitors.

Iindidi ze-elektroniki electros

Iindidi ezahlukeneyo zegrafu ezisetyenziswa njenge-electrode, nganye ilungiselelwe iimfuno ezithile:

I-Electros yeNdalo

Ukufunyanwa kwi-Idipholo ye-Idermite yendalo, ezi ze-elektroniki zinika isisombululo esinexabiso kwizicelo ezininzi. Nangona kunjalo, iipropathi zabo zinokwahluka ngokuxhomekeka kumthombo kunye neendlela zokulungisa. Zihlala zisetyenziswa kwizicelo apho ukucoceka okuphakamileyo akugxeki.

I-Syntitic I-Electrodes Electros

I-Syntitic I-Electrodes Electrodes ziveliswa ziinkqubo zobushushu obuphakamileyo kwaye zinike ulawulo oluphezulu kwiipropathi zabo, njengokucoceka, ubume bekristali, kunye nokuthambisa. Oku kuvumela ukwenziwa kwemveliso ye-elecrodes ukuhlangabezana neemfuno ezithile zomsebenzi. Zihlala zikhetha kwizicelo eziphezulu zokusebenza ezifana neLithium-i-ion.

EZINYE I-ECHODI YOKUGQIBELA EZIQHELEKILEYO

Iifom ezininzi ezikhethekileyo zegrafu ziqeshwe izicelo ezithile, kubandakanya:

• I-piyrolytication kakhulu (i-hopg): Yaziwa ngokuphumelela kwayo ngokukhethekileyo kunye nesakhiwo se-crystalline.
• Igrafu eyandisiweyo: Inomhlaba ophezulu womphezulu ngenxa yesakhiwo saso.
• I-Mesopoiner igrafu: Yenza isakhiwo sentloko kakhulu yokuphucula ukusebenza kwe-electrochemical.

IZICWANGCISO ZE-EICRADRODS

Ubume be igrafu njenge-electrode Izixhobo zenza ukuba zixabiseke kuluhlu olubanzi lweetekhnoloji:

Umgangatho ophezulu igrafu njenge-electrode Izixhobo, cinga ukukhangela iminikelo evela Hebei yaoofa carbon co., ltd., umthengisi ophambili weemveliso zekhabhoni. Banika uluhlu lweemveliso zegrafu ezilungiselelwe izicelo ezahlukeneyo.

Imiceli mngeni kunye neendlela zexesha elizayo

Ngaphandle kokusetyenziswa kwayo, imiceli mngeni ihlala isebenzisa igrafu njenge-electrode. Oku kubandakanya ukwenza intsebenzo yayo kwiimeko ezigqithisileyo, ukuphucula ubomi bayo bobomi, kunye nokuhlola ezinye iifom ukomeleza iipropathi zayo ngakumbi. Uphando oluqhubekayo lujolise ekuphuhliseni izixhobo ze-Inovelrode ephucukileyo kwi-Electrode ye-Electronec Ectrochemic ephuculweyo yokufezekisa iimfuno zetekhnoloji evelayo, ezinjengeebhetri ezilandelayo kunye neenkqubo zokugcina amandla.
