Raws li cov roj teeb lithium-ion ua tau zoo, cov khoom siv lithium-cobalt-nickel-aluminium oxide cathode electrode yog cov khoom siv tseem ceeb uas ua lub luag haujlwm tseem ceeb. Kev tsim cov roj teeb hluav taws xob rau cov tsheb fais fab yuav tsum tau siv cov khoom siv cathode electrode kom muaj zog ceev, kev nyab xeeb zoo, tsis muaj nqi thiab ib puag ncig tus phooj ywg, nrog rau lub zog siab ceev thiab lub neej ntev.

Lithium Cobalt Oxidecathode electrode khoom yog ib qho ntawm cov khoom siv cathode electrode uas muaj kev ua haujlwm siab thiab siv dav hauv tsheb fais fab. Nws yog tsim los ntawm lithium ions, npib tsib xee, cobalt thiab txhuas ions. Nws muaj qhov ua tau zoo ntawm qhov kub thiab txias thiab kev ua haujlwm ntawm lub voj voog, thiab tuaj yeem txhim kho lub zog ceev thiab lub zog ceev ntawm lub roj teeb.

Cov qauv ntawm Lithium Cobalt Oxide cathode electrode khoom yog cov txheej txheem txheej, uas zoo ib yam li cov qauv ntawm graphite. Txawm li cas los xij, piv nrog graphite, qhov sib nrug ntawm lithium-cobalt-nickel-aluminium oxide cathode electrode cov khoom siv me dua, thiab cov nqi hluav taws xob thiab tawm hluav taws xob ntau dua. Tsis tas li ntawd, cov qauv saum npoo ntawm lithium-cobalt-nickel-aluminium oxide cathode electrode cov khoom siv ntau dua, uas tuaj yeem nqus dej thiab cov pa roj carbon dioxide hauv huab cua, ua rau muaj peev xwm txo qis thiab nce hauv kev ua haujlwm sab hauv. Yog li ntawd, thiaj li yuav tau txais kev ua tau zoo ntawm lithium-cobalt-nickel-aluminium oxide cathode electrode khoom, nws yog ib qho tsim nyog los tswj nws cov qauv saum npoo thiab muaj pes tsawg leeg.

Kev npaj cov txheej txheem ntawm lithium-cobalt-nickel-aluminium oxide cathode electrode cov khoom siv feem ntau suav nrog cov kauj ruam hauv qab no: sib tov cov ntaub ntawv raw, calcination, sib tsoo thiab sieving, slurry npaj, txheej, ziab, txiav thiab nias. Cov ntaub ntawv raw yog sib xyaw raws li ib qho qauv, thiab tom qab ntawd calcined ntawm qhov kub thiab txias hauv qhov chaw inert. Cov txheej txheem calcination tuaj yeem tshem tawm cov dej noo thiab cov pa roj carbon dioxide adsorbed rau saum npoo ntawm cov ntaub ntawv raw, thiab xyuas kom meej tias cov khoom sib xyaw thiab cov qauv ntawm cov khoom siv cathode electrode yog raws li cov qauv tsim. Tom qab calcination, cov hais yog hauv av thiab sieved kom tau cov khoom nrog ib tug loj npaum li cas faib, uas yog conducive rau kev txhim kho cov kais dej ceev thiab filling ceev ntawm lub cathode electrode. Lub slurry yog npaj los ntawm kev sib tov cov khoom nrog ib tug binder thiab hnyav, thiab ces coated mus rau ib tug tam sim no collector los ua ib tug cathode electrode zaj duab xis. Thaum kawg, tom qab ziab, txiav thiab nias, cov khoom siv cathode electrode tau txais.

Lub lithium-cobal-nickel-aluminium oxide cathe cov khoom siv hluav taws xob muaj zog, kev ua haujlwm zoo, lub neej ntev thiab lwm yam ntxwv. Nws yog dav siv hauv tsheb fais fab, cov cuab yeej hluav taws xob, lub zog cia roj teeb thiab lwm yam. Txawm li cas los xij, vim yog tus nqi siab ntawm cov khoom siv raw thiab cov txheej txheem npaj, nws yuav tsum tau txhim kho ntxiv. Tsis tas li ntawd, nrog rau kev txhim kho thev naus laus zis thiab kev hloov pauv ntawm kev lag luam ib puag ncig, cov khoom siv cathode electrode tshiab yuav maj mam hloov cov ntaub ntawv ib txwm muaj. Yog li ntawd, kev tshawb fawb txuas ntxiv thiab tsim cov khoom siv cathode electrode tshiab yog xav tau los ua kom tau raws li kev xav tau ntawm kev lag luam thiab txhim kho cov khoom lag luam.
