Kwicandelo le-electrochemistry, ukusebenza kakuhle kunye nokusebenza kweeseli ze-electrochemical kubaluleke kakhulu. Phakathi kwezinto ezahlukeneyo ezinegalelo ekusebenzeni kakuhle, ii-anode ezisisigxina zidlala indima ebalulekileyo. Ezi electrode ezisisigxina zingaphezulu nje kwezinto ezingasebenziyo; zingumqolo wenkqubo ye-electrochemical, ezichaphazela i-reaction kinetics iyonke, uzinzo, kunye nobomi beseli.
Ii-anode ezizinzileyoZenzelwe ukuba zihlale zikwindawo ezinzileyo ngexesha lenkqubo ye-electrochemical, zibonelela ngeqonga elizinzileyo leempendulo ze-oxidation ezenzeka kwi-anode. Olu zinzo lubalulekile ekugcineni ukusebenza okuzinzileyo ngokuhamba kwexesha. Ngokungafaniyo nee-anode ezishukumayo okanye ezijikelezayo, ii-anode ezimileyo zisusa ubunzima obuhambelana nokuhamba koomatshini, okwenza uyilo kunye nokusebenza kweeseli ze-electrochemical kube lula.
Enye yezona nzuzo ziphambili zee-anode ezimileyo kukukwazi kwazo ukwandisa ukusebenza kakuhle kwee-electrochemical reactions. Ngokubonelela ngomphezulu ozinzileyo wokudluliselwa kwee-electron, ii-anode ezimileyo zikhuthaza i-oxidation yee-reactants, ngaloo ndlela zonyusa uxinano lwangoku kwaye ziphucule ukusebenza kweeseli iyonke. Oku kubaluleke kakhulu kwizicelo ezifana ne-electrolysis, ii-fuel cells, kunye neebhetri, apho ukwandisa ukusebenza kakuhle kwee-electrochemical reactions kunokuchaphazela kakhulu imveliso yamandla kunye neendleko zokusebenza.
Ukongeza, ii-anode ezisisigxina zinokuyilwa kusetyenziswa izinto ezahlukeneyo ukuze kuphuculwe ukusebenza kwazo. Izinto eziqhelekileyo ziquka i-graphite, i-platinum, kunye nee-oxides ezahlukeneyo zesinyithi, nganye kuzo ineempawu ezizodwa ezinokuphucula impendulo ye-electrochemical. Umzekelo, ii-anode ze-graphite zaziwa ngokuqhuba kwazo kakuhle kunye nokuzinza kweekhemikhali, nto leyo ezenza zibe zilungele ukusetyenziswa ngeendlela ezahlukeneyo. Kwelinye icala, ii-anode zeplatinum zihlala zisetyenziswa kwiiseli zamafutha ezisebenza kakuhle ngenxa yeempawu zazo ezintle ze-catalytic.
Uyilo lwe-anode esisigxina ludlala indima ebalulekileyo ekusebenzeni kwayo. Izinto ezifana nommandla womphezulu, i-porosity, kunye ne-morphology zinokuchaphazela kakhulu ukusebenza kwe-electrochemical. Indawo enkulu yomphezulu ivumela iindawo ezisebenzayo ukuba zisabele, ngelixa isakhiwo esineembobo sinokuphucula ukuthuthwa kwezinto, siqinisekise ukuba ii-reactants zifikelela kwi-anode ngokufanelekileyo. Abaphandi bahlala behlola uyilo olutsha kunye nezixhobo ukuphucula ngakumbi ukusebenza kwe-anode esisigxina kunye nokunyusa imida yetekhnoloji ye-electrochemical.
Ukongeza ekuphuculeni ukusebenza kakuhle, ii-anode ezizinzileyo zinceda ekwandiseni ubomi beeseli ze-electrochemical kunye nokuphucula uzinzo lweeseli. Ngokubonelela ngeqonga elihambelanayo nelithembekileyo leempendulo, zinceda ekunciphiseni imiba efana nokuwohloka kwe-electrode kunye nokungashukumi, okunokubangela ukuba ukusebenza kwehle ngokuhamba kwexesha. Olu zinzo lubaluleke kakhulu kwizicelo zoshishino, apho iindleko zokungasebenzi kunye nokugcinwa ziphezulu.
Njengoko imfuno yezisombululo zamandla ezisebenzayo iqhubeka ikhula, ukubaluleka kwee-anode ezisisigxina kwiiseli ze-electrochemical akunakuthathelwa ingqalelo. Amandla azo okwandisa ukusebenza kakuhle kwempendulo, ukuphucula uzinzo, kunye nokwandisa ubomi beenkqubo ze-electrochemical kuzenza zibe yinxalenye ebalulekileyo kuphuhliso lwetekhnoloji yamandla aphucukileyo. Ukusuka kumandla avuselelekayo ukuya kwizisombululo zokugcina amandla, ii-anode ezisisigxina zivula indlela yekamva elizinzileyo nelisebenzayo.
Isishwankathelo,ii-anode ezizinzileyongokwenene zingumqolo weeseli ze-electrochemical ezisebenzayo. Uyilo lwazo, ukukhethwa kwezinto, kunye nokuzinza kokusebenza zizinto eziphambili ezichaphazela ukusebenza kwezicelo ezahlukeneyo ze-electrochemical. Njengoko uphando kunye nophuhliso kweli candelo luqhubeka luhambela phambili, sinokulindela ukubona izisombululo ezintsha ezisebenzisa iimpawu ezizodwa ze-anodes ezisisigxina, ziqhubela phambili iteknoloji ye-electrochemical kunye nokusetyenziswa kwayo kubomi bethu bemihla ngemihla.
