Hauv kev ua haujlwm ntawm electrochemistry, kev ua tau zoo thiab kev ua haujlwm ntawm cov hlwb electrochemical yog qhov tseem ceeb tshaj plaws. Ntawm cov khoom sib txawv uas ua rau muaj txiaj ntsig zoo, anodes nyob ruaj khov ua lub luag haujlwm tseem ceeb. Cov electrodes nyob ruaj ruaj no ntau dua li cov khoom siv passive xwb; Lawv yog cov caj qaum ntawm cov txheej txheem electrochemical, cuam tshuam rau tag nrho cov tshuaj tiv thaiv kinetics, stability, thiab lub neej ntawm lub cell.
Nyob ruaj ruaj anodesyog tsim los kom nyob twj ywm nyob rau hauv ib qho chaw ruaj khov thaum lub sij hawm electrochemical txheej txheem, muab ib tug ruaj khov platform rau oxidation tshwm sim ntawm lub anode. Qhov kev ruaj ntseg no yog qhov tseem ceeb rau kev tswj xyuas kev ua haujlwm zoo ib yam nyob rau lub sijhawm. Tsis zoo li txav los yog tig anodes, nyob ruaj ruaj anodes tshem tawm cov complexities txuam nrog txhua yam txav, ua rau kev tsim thiab kev ua haujlwm ntawm cov hlwb electrochemical yooj yim dua.
Ib qho txiaj ntsig tseem ceeb ntawm cov anodes nyob ruaj ruaj yog lawv lub peev xwm los ua kom muaj txiaj ntsig ntawm cov tshuaj tiv thaiv electrochemical. Los ntawm kev muab qhov chaw ruaj khov rau kev hloov hluav taws xob, cov anodes nyob ruaj ruaj txhawb oxidation ntawm reactants, yog li ua kom ceev tam sim no thiab txhim kho tag nrho cov xov tooj ntawm tes. Qhov no yog ib qho tseem ceeb tshwj xeeb hauv kev siv xws li electrolysis, roj hlwb, thiab roj teeb, qhov ua kom zoo tshaj plaws ntawm cov tshuaj tiv thaiv electrochemical tuaj yeem cuam tshuam rau cov khoom siv hluav taws xob thiab cov nqi khiav lag luam.
Tsis tas li ntawd, anodes nyob ruaj ruaj tuaj yeem tsim siv ntau yam khoom siv los ua kom zoo dua lawv cov kev ua tau zoo. Cov khoom siv feem ntau suav nrog graphite, platinum, thiab ntau yam hlau oxides, txhua tus muaj cov khoom tshwj xeeb uas tuaj yeem txhim kho cov tshuaj tiv thaiv electrochemical. Piv txwv li, graphite anodes paub txog lawv cov conductivity zoo heev thiab tshuaj stability, ua rau lawv zoo tagnrho rau ntau yam kev siv. Ntawm qhov tod tes, platinum anodes feem ntau yog siv rau hauv cov roj ntsha ua haujlwm siab vim lawv cov khoom catalytic zoo heev.
Kev tsim ntawm qhov chaw nres tsheb anode kuj tseem ua lub luag haujlwm tseem ceeb hauv nws cov txiaj ntsig. Cov yam ntxwv xws li thaj chaw nto, porosity, thiab morphology tuaj yeem cuam tshuam rau kev ua haujlwm ntawm electrochemical. Ib thaj chaw loj dua tso cai rau ntau qhov chaw ua haujlwm kom hnov mob, thaum cov qauv ntxeem tau tuaj yeem txhim kho cov khoom thauj, xyuas kom cov reactants ncav cuag lub anode zoo. Cov kws tshawb fawb niaj hnub tshawb nrhiav cov qauv tsim tshiab thiab cov khoom siv los txhim kho kev ua haujlwm ntawm cov anodes nyob ruaj ruaj thiab thawb cov kev txwv ntawm cov tshuab electrochemical.
Ntxiv nrog rau kev txhim kho kev ua tau zoo, cov anodes nyob ruaj ruaj pab txuas ntxiv lub neej ntawm electrochemical hlwb thiab txhim kho cell stability. Los ntawm kev muab lub platform zoo ib yam thiab txhim khu kev qha rau cov tshuaj tiv thaiv, lawv pab txo cov teeb meem xws li electrode degradation thiab passivation, uas tuaj yeem ua rau kev ua haujlwm poob qis thaum lub sijhawm. Qhov kev ruaj ntseg no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov kev lag luam, qhov chaw poob qis thiab cov nqi kho mob siab.
Raws li qhov kev thov rau cov kev daws teeb meem zoo txuas ntxiv mus ntxiv, qhov tseem ceeb ntawm cov anodes nyob ruaj ruaj hauv cov hlwb electrochemical tsis tuaj yeem kwv yees. Lawv lub peev xwm los ua kom cov tshuaj tiv thaiv kev ua tau zoo, txhim kho kev ruaj ntseg, thiab txuas ntxiv lub neej ntawm cov tshuab electrochemical ua rau lawv yog ib qho tseem ceeb hauv kev txhim kho cov thev naus laus zis thev naus laus zis. Los ntawm lub zog tauj dua tshiab mus rau cov kev daws teeb meem ntawm lub zog, cov anodes nyob ruaj ruaj tab tom ua txoj hauv kev rau lub neej yav tom ntej kom muaj txiaj ntsig zoo dua.
Hauv cov ntsiab lus,anodes nyob ruaj ruajyog cov caj qaum ntawm cov hlwb electrochemical. Lawv tsim, xaiv cov khoom siv, thiab kev ua haujlwm ruaj khov yog qhov tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm ntau yam kev siv electrochemical. Raws li kev tshawb fawb thiab kev loj hlob hauv daim teb no txuas ntxiv mus, peb tuaj yeem cia siab tias yuav pom ntau cov kev daws teeb meem tshiab uas siv cov khoom tshwj xeeb ntawm cov anodes nyob ruaj ruaj, nce qib electrochemical technology thiab nws cov kev siv hauv peb lub neej txhua hnub.
