Kev soj ntsuam ntawm txheej txheej txheem rau cov roj teeb lithium-ion

Raws li paub zoo, qhov zoo electrode substrate ntawm lithium-ion roj teeb yog aluminium ntawv ci, thiab qhov tsis zoo electrode substrate yog tooj liab ntawv nyiaj. Tom qab txheej txheej, nws tau ua rau hauv qhov zoo electrode kauj thiab tsis zoo electrode kauj, uas yog siv rau cov kauj ruam tom ntej. Qhov zoo ntawm cov khoom siv hluav taws xob tau txiav txim siab qee qhov kev ua tau zoo ntawm lub roj teeb, thiab cov txheej txheem ntawm lub substrate yog ib qho tseem ceeb heev ntawm tag nrho cov txheej txheem tsim cov roj teeb!

Cov txheej txheem txheej txheej tau hloov zuj zus los ntawm cov txheej txheem immersion thiab extrusion mus rau ntau tshaj ob-sided ib txhij txheej, txhua yam tsom rau kev txhim kho cov txheej txheem zoo thiab kev ua haujlwm ntawm cov electrode. Qee qhov kev lag luam muaj zog hauv Suav teb tau nqis peev nyiaj ntau los ua kom paub cov tshuab electrode kim nyob txawv teb chaws txhawm rau tsim cov roj teeb lithium-ion txhim khu kev qha.

 

Cov txheej txheem dav dav ntawm txheej txheej: txheej txheej substrate (hlau ntawv ci) raug tso tawm los ntawm cov khoom siv unwinding thiab pub rau hauv lub tshuab txheej. Qhov pib thiab qhov kawg ntawm lub substrate yog txuas mus rau hauv ib tug nruam sawb ntawm lub rooj splicing, thiab ces muab tso rau hauv lub nro adjustment ntaus ntawv thiab tsis siv neeg kho ntaus ntawv los ntawm lub rub device. Tom qab kho qhov nro thiab txoj hauj lwm ntawm txoj kev ua yeeb yaj kiab, lawv nkag mus rau cov khoom siv txheej txheej. Polar muab tshuaj txhuam yog coated nyob rau hauv cov seem raws li predetermined txheej txheej thiab qhov ntev ntawm cov khoom siv txheej. Thaum lub sij hawm ob-sided txheej, cov txheej pem hauv ntej thiab qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Cov coated ntub electrode raug xa mus rau lub tshuab ziab khaub ncaws kom qhuav, thiab qhov ziab ziab yog teem raws li txheej ceev thiab txheej thickness. Tom qab ziab, cov polarizers raug kho kom nruj thiab kho tau ua ntej yuav dov rau cov kauj ruam tom ntej.
Cov txheej txheej ntawm lub ncov qaumteb qabteb yog cov tuab, nrog cov txheej txheem loj thiab cov khoom ziab kom qhuav. Tam sim no, cov cuab yeej siv feem ntau yog huab cua kub cuam tshuam kom qhuav. Qhov zoo electrode substrate yog aluminium ntawv ci, uas muaj cov khoom siv tshuaj lom neeg thiab yooj yim oxidized. Thaum lub sij hawm tsim cov txheej txheem ntawm txhuas ntawv ci, ib tug tuab oxide zaj duab xis yog tsim, uas tiv thaiv oxidation ntxiv ntawm cov ntawv ci. Vim lub nyias thiab ntxeem tau ntawm oxide zaj duab xis, nws yog mos thiab muaj zoo adsorption zog. Txawm li cas los xij, qhov kub thiab av noo tuaj yeem ua rau cov oxide zaj duab xis puas, ua kom cov tshuaj tiv thaiv oxidation nrawm dua. Tam sim no, feem ntau ntawm lawv siv ib txoj kev txheej txheej. Thaum thawj sab yog coated, sab sab yog kiag li raug rau cov cua kub, thaum lub qhuav kub cua rau txheej (roj raws li) yuav tsum nyob ib ncig ntawm 130 degree. Yog hais tias cov dej noo nyob rau hauv cov huab cua kub tsis tswj tau zoo, nws yuav ua rau oxidation ntawm aluminium ntawv ci thiab cuam tshuam rau kev sib txuas ntawm cov khoom zoo electrode thiab aluminium ntawv ci, thiab tseem ua rau detachment.
Cov neeg tsim khoom ntawm cov tshuab txheej txheej hauv Tebchaws Meskas thiab Nyij Pooj tau tsim cov txheej txheem ob txheej txheej ib txhij los daws cov teeb meem kev siv hluav taws xob thiab aluminium foil oxidation teeb meem ntawm cov txheej txheem txheej txheej tshuab, ua kom daws tau cov teeb meem txhuas ntawv oxidation thaum txheej txheej. Txawm li cas los xij, tus nqi siab tshaj ntawm ob tog ib txhij txheej tshuab tsis muaj nqis rau cov tuam txhab roj teeb zoo tib yam.
