Emkhakheni we-electrochemistry, ukusebenza kahle nokusebenza kwamaseli e-electrochemical kubaluleke kakhulu. Phakathi kwezingxenye ezihlukahlukene ezifaka isandla ekusebenzeni kahle, ama-anode amile adlala indima ebalulekile. Lawa ma-electrode amile angaphezulu nje kwezingxenye ezingenzi lutho; ziwumgogodla wesistimu ye-electrochemical, ethonya i-kinetics yokusabela jikelele, ukuzinza, nokuphila kweseli.
Ama-anode amileaklanyelwe ukuhlala endaweni engashintshi phakathi nenqubo ye-electrochemical, ehlinzeka ngendawo ezinzile yokusabela kwe-oxidation okwenzeka ku-anode. Lokhu kuzinza kubalulekile ekugcineni ukusebenza okungaguquki ngokuhamba kwesikhathi. Ngokungafani nama-anode anyakazayo noma ajikelezayo, ama-anode amile asusa ubunkimbinkimbi obuhambisana nokunyakaza kwemishini, okwenza ukwakheka nokusebenza kwamaseli e-electrochemical kube lula.
Enye yezinzuzo eziyinhloko zama-anode amile yikhono lawo lokwandisa ukusebenza kahle kokusabela kwe-electrochemical. Ngokuhlinzeka ngendawo ezinzile yokudluliswa kwama-electron, ama-anode amile athuthukisa i-oxidation yama-reactants, ngaleyo ndlela andise ukuminyana kwamanje futhi athuthukise ukusebenza kweseli kukonke. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza ezifana ne-electrolysis, amaseli kaphethiloli, namabhethri, lapho ukukhulisa ukusebenza kahle kokusabela kwe-electrochemical kungase kuthinte kakhulu ukukhishwa kwamandla nezindleko zokusebenza.
Ukwengeza, ama-anode amile angaklanywa kusetshenziswa izinto ezahlukahlukene ukuze kuthuthukiswe ukusebenza kwawo. Izinto ezivamile zihlanganisa i-graphite, i-platinum, nama-oxide ensimbi ahlukahlukene, ngayinye enezici eziyingqayizivele ezingathuthukisa ukusabela kwe-electrochemical. Isibonelo, ama-graphite anode aziwa ngokusebenza kwawo okuhle kakhulu kanye nokuzinza kwamakhemikhali, okuwenza abe ekahle ezinhlobonhlobo zezicelo. Ngakolunye uhlangothi, ama-anode e-platinum avame ukusetshenziswa kumaseli kaphethiloli asebenza kahle kakhulu ngenxa yezakhiwo zawo ezinhle kakhulu zokuthuthukisa.
Ukwakhiwa kwe-anode emile nakho kudlala indima ebalulekile ekusebenzeni kwayo. Izinto ezifana nendawo engaphezulu, i-porosity, kanye ne-morphology zingathinta kakhulu ukusebenza kwe-electrochemical. Indawo engaphezulu ivumela amasayithi asebenza kakhulu ukuthi asabele, kuyilapho isakhiwo esinezimbotshana singathuthukisa ukuthuthwa kwempahla, siqinisekise ukuthi ama-reactants afinyelela i-anode kahle. Abacwaningi bahlala behlola imiklamo emisha nezinto zokwakha ukuze baqhubeke nokuthuthukisa ukusebenza kwama-anode amile futhi basunduze imikhawulo yobuchwepheshe be-electrochemical.
Ngaphezu kokuthuthukisa ukusebenza kahle, ama-anode amile asiza ukunweba impilo yamangqamuzana e-electrochemical futhi athuthukise ukuqina kwamaseli. Ngokuhlinzeka ngenkundla engaguquki nethembekile yokusabela, basiza ekwehliseni izinkinga ezinjengokuwohloka kwe-electrode kanye ne-passivation, engabangela ukusebenza kwehle ngokuhamba kwesikhathi. Lokhu kuzinza kubaluleke kakhulu ekusetshenzisweni kwezimboni, lapho izindleko zesikhathi sokuphumula nezokugcina ziphezulu.
Njengoba isidingo sezixazululo ezisebenza kahle zamandla siqhubeka sikhula, ukubaluleka kwama-anode amile kumaseli e-electrochemical angeke kubukelwe phansi. Ikhono labo lokwandisa ukusebenza kahle kokusabela, ukuthuthukisa ukuzinza, nokwelula impilo yezinhlelo ze-electrochemical kubenza babe yingxenye ebalulekile ekuthuthukisweni kobuchwepheshe bamandla athuthukile. Kusukela kumandla avuselelekayo kuya ezixazululweni zokugcina amandla, ama-anode amile avula indlela yekusasa elisimeme nelisebenza ngempumelelo.
Ngokufigqiwe,ama-anode amileziwumgogodla wamaseli e-electrochemical asebenzayo. Ukuklama kwabo, ukukhethwa kwezinto ezibonakalayo, nokuzinza kokusebenza yizici ezibalulekile ezithonya ukusebenza kohlu olubanzi lwezinhlelo zokusebenza ze-electrochemical. Njengoba ucwaningo nentuthuko kulo mkhakha iqhubeka nokuthuthuka, singalindela ukubona izixazululo ezintsha ezithuthukisa izakhiwo eziyingqayizivele ze-anode emile, ukuthuthukiswa kobuchwepheshe be-electrochemical kanye nokusebenzisa kwabo ekuphileni kwethu kwansuku zonke.
