Lithium roj teebyog ib hom roj teeb uas siv lithium hlau los yog lithium alloy ua cov khoom siv electrode tsis zoo thiab siv cov tshuaj uas tsis yog-aqueous electrolyte. Vim muaj cov tshuaj lom neeg muaj zog heev ntawm lithium hlau, kev ua haujlwm, kev cia, thiab kev siv cov lithium hlau muaj qhov xav tau ib puag ncig siab heev. Tom ntej no, cia peb saib ntawm homogenization, txheej, thiab dov txheej txheem hauv kev npaj cov roj teeb lithium.
Qhov zoo thiab tsis zoo electrode homogenization
Cov electrode ntawm lithium-ion roj teeb yog qhov tseem ceeb tshaj plaws ntawm cov roj teeb ntawm tes. Qhov zoo thiab tsis zoo electrode homogenization yog hais txog cov txheej txheem kev npaj ntawm slurry coated ntawm cov nplooj ntawv zoo thiab tsis zoo electrode ntawm lithium ion. Kev npaj ntawm slurry yuav tsum sib tov cov khoom zoo electrode, cov khoom tsis zoo electrode, tus neeg sawv cev conductive thiab cov binder. Lub slurry npaj yuav tsum yog uniform thiab ruaj khov.
Txawv lithium roj teeb manufacturers muaj lawv tus kheej homogenization txheej txheem qauv. Qhov kev txiav txim ntawm kev ntxiv cov ntaub ntawv, qhov kev faib ua feem ntawm kev ntxiv cov ntaub ntawv thiab cov txheej txheem stirring nyob rau hauv homogenization txheej txheem muaj ib tug zoo kawg nkaus lub luag hauj lwm rau homogenization nyhuv. Tom qab homogenization, slurry yuav tsum tau kuaj xyuas cov ntsiab lus ntawm cov khoom, viscosity, fineness, thiab lwm yam kom ntseeg tau tias cov slurry ua tau raws li qhov yuav tsum tau ua.
Txheej
Txheej txheej txheej yog txheej txheem raws li kev tshawb fawb ntawm cov kua dej, nyob rau hauv uas ib los yog ntau txheej ntawm cov kua yog coated rau ntawm ib tug substrate. Lub substrate feem ntau yog cov ntaub ntawv hloov tau yooj yim lossis cov ntawv thaub qab, thiab tom qab ntawd cov txheej txheem ua kua txheej yog qhuav hauv qhov cub lossis kho kom tsim cov txheej txheej zaj duab xis nrog cov haujlwm tshwj xeeb.
Txheej yog txheej txheem tseem ceeb hauv kev npaj cov roj teeb hlwb. Qhov zoo ntawm txheej yog ncaj qha ntsig txog qhov zoo ntawm lub roj teeb. Nyob rau tib lub sijhawm, cov roj teeb lithium-ion yog qhov rhiab heev rau cov dej noo vim cov yam ntxwv ntawm lub cev. Cov kab dej noo tuaj yeem cuam tshuam loj rau kev ua haujlwm hluav taws xob ntawm lub roj teeb; cov txheej txheem ntawm txheej txheej yog ncaj qha ntsig txog cov tswv yim ntsuas xws li tus nqi thiab tus nqi tsim nyog.
Txheej txheej ntau lawm
Lub coated substrate yog unwound los ntawm lub unwinding ntaus ntawv thiab pub rau hauv lub tshuab txheej. Tom qab lub taub hau thiab tus Tsov tus tw ntawm lub substrate yog txuas mus rau tsim ib tug nruam txoj siv nyob rau hauv lub splicing rooj, lawv tau pub rau hauv lub nro adjustment ntaus ntawv thiab tsis siv neeg deviation kho ntaus ntawv los ntawm lub rub device, thiab nkag mus rau lub txheej txheej tom qab kho cov ntawv txoj kev nro thiab daim ntawv txoj hauj lwm. Tus ncej daim slurry yog coated nyob rau hauv seem nyob rau hauv lub txheej txheej raws li lub predetermined txheej thiab dawb paug ntev.
Thaum txheej txheej ob sab, 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 khoob khoob khoob khoob khoob khoob khoob. Cov electrode ntub dej tom qab txheej yog xa mus rau lub tshuab ziab khaub ncaws kom qhuav. Lub ziab kub yog teem raws li txheej ceev thiab txheej thickness. Cov electrode qhuav yog dov tom qab kev hloov kho nro thiab tsis siv neeg hloov pauv hloov rau cov kauj ruam tom ntej ntawm kev ua haujlwm.
Rolling
Cov txheej txheem dov ntawm lithium roj teeb ncej yog cov txheej txheem ntau lawm uas sib npaug ntawm cov ntaub ntawv raw xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov binders ntawm cov ntawv hlau. Los ntawm cov txheej txheem dov, cov ncej ncej tuaj yeem muaj qhov siab dua electrochemical active cheeb tsam, yog li kev txhim kho lub zog ceev thiab kev them nqi thiab kev ua haujlwm ntawm lub roj teeb. Nyob rau tib lub sijhawm, cov txheej txheem dov kuj tseem tuaj yeem ua rau cov ncej ncej muaj lub zog ntau dua thiab ua haujlwm zoo, uas pab txhim kho lub voj voog lub neej thiab kev nyab xeeb ntawm lub roj teeb.
Rolling txheej txheem ntau lawm
Cov txheej txheem ntawm dov txheej txheem ntawm lithium roj teeb ncej feem ntau suav nrog cov khoom siv raw, kev sib xyaw, compaction, shaping thiab lwm yam txuas.
Raw khoom npaj yog sib tov ntau yam raw cov ntaub ntawv tusyees thiab ntxiv tsim nyog tus nqi ntawm cov kuab tshuaj rau nplawm kom tau ib tug ruaj khov slurry.
Qhov sib txuas sib txuas yog sib tov ntau yam khoom siv sib xyaw kom sib xyaw ua ke thiab ua kom zoo.
Cov kev sib txuas sib txuas yog nias lub slurry los ntawm cov menyuam xovxwm kom cov khoom siv cov khoom siv tau zoo sib xws los ua ib qho ncej nrog lub zog ntawm cov qauv. Kev sib txuas shaping yog kho tus ncej nrog qhov kub thiab txias los ntawm cov khoom siv xws li kub xovxwm los kho cov duab thiab qhov loj ntawm cov ncej.
