1. Ua tiav cov khoom raw
(1) Lithium cobaltate: dehydrated. Feem ntau, nws yog ci ntawm qhov siab ntawm 120 oC rau li 2 teev.
(2) Tus neeg sawv cev cwj pwm: lub cev qhuav dej. Feem ntau, nws yog ci ntawm 200 ° C rau 2 teev los yog li ntawd.
(3) Adhesive: dehydrated. Feem ntau, nws yog ci ntawm 120-140 oC rau 2 teev ntawm kev ntsuas siab, thiab ntsuas kub yog txiav txim siab los ntawm qhov hnyav ntawm molecular.
(4) NMP: cev qhuav dej. Siv lub cev qhuav dej qhuav qhuav los yog siv cov chaw siv tshwj xeeb rov qab siv rau kev siv ncaj qha.
2, qhov sib tov ntawm raw cov ntaub ntawv
(1) Tshem tawm ntawm cov binder (raws li tus qauv concentration) thiab kev kho cua sov.
(2) Lithium cobaltate thiab kev sib txuas lus ntawm lub pob milling: hmoov yog thawj zaug sib xyaw, thiab cov qauv tshuaj dej lithium thiab tus neeg sawv cev sib txuas lus ua ke ua ke los txhim kho cov agglomeration thiab kev sib tsoo. Tom qab ua formulated rau hauv slurry, nws tsis yog muab faib rau hauv phau ntawv, thiab lub pob milling lub sij hawm feem ntau yog li 2 xuab moos; yuav kom tsis txhob tov impurities, ib pob agate feem ntau siv los ua ib pob zeb meson.
3. Dispersion thiab qe ntawm cov hmoov qhuav:
(1) Ntsiab Lus: Cov hmoov av muab tso rau saum cua. Raws li lub sij hawm dhau mus, ib feem ntawm huab cua yuav tsum adsorbed rau ntawm qhov khoom. Tom qab lub fwj pob ntxiv, cov kua thiab cov roj pib los sib tw rau cov khoom nto; Yog tias cov khoom thiab cov pa adsorbed Cov kua muaj zog dua cov kua, thiab cov kua tsis ntub cov khoom; yog tias cov kua hluav taws xob muaj zog tawm suab yog qhov muaj zog dua cov roj cov adsorption quab yuam, cov kua tau ntub cov khoom thiab ua kom tsis muaj roj. Thaum lub kaum pob ntub yog ≤ 90 degrees, qhov khov yog wetted. Thaum lub kaum ntse ntse yog qhov siab tshaj ≤ 90 degrees, cov khib nyiab tsis wetted. Txhua tus tswv cuab ntawm cov khoom siv zoo electrode tuaj yeem muaj dej khov los ntawm cov tog raj, ces cov hmoov zoo zoo kuj yooj yim.
(2) Cov nyhuv ntawm cov dispersion txoj kev ntawm dispersion:
A. Txoj kev lub sij hawm (ntev lub sij hawm, cov nyhav tsis zoo, tab sis tsis ua rau cov qauv ntawm cov ntaub ntawv);
B, txoj kab txiav; kev sib hloov lossis kev sib hloov thiab kev sib tw (lub sijhawm luv luv, kev ua haujlwm zoo, tab sis nws yuav ua rau cov khoom ntawm tus kheej).
1. Cov cawv ntawm cov nplaum nplaum rau ntawm qhov ceev ceev. Cov paddles agitating feem ntau muaj xws li ib tus qauv zoo nkauj, ib tus npuj npuj, ib qho zoo nkauj, ib lub iav, thiab cov zoo li. Feem ntau, cov kab npauj npaim, npauj npaim, thiab duav paddles yog siv rau thawj theem ntawm cov khoom los yog cov khoom xyaw uas nyuaj rau disperse; lub ntsej muag khoob thiab cov iav siv los muab faib rau lub xeev tsis muaj zog, thiab qhov tshwm sim zoo.
2. Cov nyhuv ntawm cov nplawm ceev ntawm qhov ceev ceev. Feem ntau hais lus, qhov siab dua tus nplawm ceev, qhov ceev ceev qhov ceev ceev, tiam sis qhov ntau dua qhov kev puas tsuaj rau cov ntaub ntawv nws tus kheej thiab cov khoom siv.
3. Cov nyhuv ntawm concentration ntawm tus ceev dispersion. Feem ntau, qhov me me qhov slurry concentration, ceev qhov ceev ceev, tab sis dhau nyias nyias yuav ua rau pov tseg ntawm cov khoom thiab cov hnyuv ntxwm ntawm cov nag slurry.
4. Cov nyhuv ntawm cov khoom siv dag zog. Qhov ntau dua qhov concentration, qhov ntau dua qhov zog softening thiab lub siab zog tsevneeg; qhov tsawg dua qhov concentration, qhov me zog qhov ua tau lub zog.
5. Cov nyhuv ntawm lub tshuab nqus tsev rau ntawm qhov ceev ceev. Lub tshuab nqus tsev yuav ua rau cov pa tawm ntawm qhov sib txawv ntawm qhov khoom thiab qhov chaw, thiab txo qhov teeb meem ntawm cov kua adsorption; qhov teeb meem ntawm uniformly dispersing cov khoom nyob rau hauv qhov mob ntawm tag nrho poob los yog txo lub ntiajteb txawj nqus yuav zoo heev txo.
6. Cov nyhuv ntawm qhov kub ntawm qhov ceev ceev. Nyob rau hauv ib qho kev ntsuas kub, cov slurry muaj zoo fluidity thiab yog yooj yim los disperse. Kub slurry yog yooj yim mus rau crust, thiab fluidity ntawm heev txias slurry yuav raug heev txo.
7. Dilute. Lub slurry yog hloov mus rau ib tug haum concentration rau chaw coating.
