tus nqi roj teeb lithium yuav tsum tau txo qis
Tsis ntev los no, Tesla tshaj tawm ntawm nws lub quarter thib ob daim ntawv tshaj tawm txog nyiaj txiag lub rooj sib tham tias nws 4680 roj teeb uas siv cov txheej txheem cathode qhuav tau pib sib sau ua ntej tus qauv Cybertruck thiab tau nkag mus rau hauv lub tsheb kuaj thiab pov thawj theem. Nws npaj yuav loj-tsim thiab txhim kho lub tsheb ua ntej lub xyoo xaus. 4680 roj teeb uas siv tag nrho cov electrodes qhuav.
Qhov no txhais tau hais tias Tesla cov electrodes qhuav tau ua tiav qhov kev tsim khov thiab nkag mus rau theem kev pov thawj ntau lawm, thiab nws cov roj teeb cylindrical loj yog thaum kawg ib kauj ruam los ze zog rau cov nqi qis, qis zog tsim khoom.
Cov tshuab ziab electrode muaj qhov pom tseeb zoo, thiab PTFE yuav tsum muaj qhov xav tau tawg
Cov txheej txheem qhuav electrode yog ib qho kev hloov kho tshiab piv rau cov txheej txheem ntub dej. Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, qhuav electrodes muaj tsawg dua cov kauj ruam, txo cov nqi tsim khoom thiab lub zog noj, thiab cov khoom siv raw yog ib puag ncig zoo thiab tsim nyog rau ntau lawm; Hais txog roj teeb ua haujlwm, cov roj teeb qhuav tuaj yeem ua tiav lub zog hluav taws xob siab dua thiab lub roj teeb ntau dua. Kev ua tau zoo thiab cov khoom siv kho tshuab zoo dua; ntawm daim ntawv thov, cov txheej txheem qhuav electrode yog qhov tsim nyog rau kev tsim cov khoom siv hluav taws xob tshiab xws li cov roj teeb hauv lub xeev thiab 4680 roj teeb.
Cov txheej txheem qhuav electrode tuaj yeem muab faib ua cov hmoov ntsiav tshuaj, hmoov txau txoj kev, txoj kev khi fiber ntau, thiab lwm yam.
Feem ntau siv fibrillating adhesives muaj xws li PTFE, ETEF thiab FEP. Ntawm lawv, PTFE yog qhov kev xaiv zoo tshaj plaws ntawm cov nplaum, feem ntau vim tias PTFE polymerizes nrog qhov hnyav dua molecular, tuaj yeem tsim cov fibrils ntev dua, thiab muaj cov khoom zoo.
Raws li 3,000 tons ntawm cov khoom zoo thiab tsis zoo electrode xav tau ntawm 1Gwh, thiab xam raws li PTFE ntxiv tus nqi ntawm 5%-10%, kwv yees li 200 tons ntawm PTFE xav tau. EVTank kwv yees tias thoob ntiaj teb lithium-ion roj teeb xa khoom yuav ncav cuag 1926.0GWh thiab 5004.3GWh hauv 2025 thiab 2030 raws. Yog hais tias cov electrode qhuav permeability nce mus txog 3% thiab 15% nyob rau hauv 2025 thiab 2030 raws, qhov sib thooj PTFE xav tau yuav yog kwv yees li 11,{18}} tons thiab 150,{20}} tons feem.
