Lithium roj teeb xim yog qhov teeb meem uas nquag thaum lub tsheb tsim khoom lag luam thiab tuaj yeem cuam tshuam cov roj teeb (xws li muaj peev xwm, lub neej ntev, thiab kev nyab xeeb). Hauv qab no yog kev tshuaj ntsuam ntawm cov ua rau thiab cov kev daws teeb meem rau txheej tawg:
Lub ntsiab ua rau txheej tawg
1. Slurry formulation teeb meem
Cov ntsiab lus qis: Cov ntsiab lus siab hauv cov slurry ua rau muaj kev ntxhov siab ntau thaum ziab, ua rau txheej tawg.
Tsis txaus lossis tsis sib xws binder dispersion: tsis txaus los yog ua rau PVDF, CMC / SBR) ua rau muaj cov xim tsis txaus thiab cov khoom siv txheej txheej tsis txaus thiab cov txheej txheej tsis txaus.
Cov neeg sawv cev ua haujlwm tsis tsim nyog: ntau li Carbon Dub, CNT) cov ntsiab lus tuaj yeem ua rau cov neeg txom nyem slurry flowility thiab kev ntxhov siab thaum ziab.
Tsis zoo slurry rheology: tsis txaus ntseeg: tsis txaus ntseeg lossis muaj viscosity ntau dhau tuaj yeem ua rau muaj kev tsis zoo thaum lub sijhawm txheej thiab tawg tom qab ziab.
2. Impt Khov Txheej Txheem tsis
Uneven txheej thickness: ntau dhau ntawm cov cheeb tsam tuab cov kev ua tsis zoo ntsws thaum ziab, ua rau tawg. Mismatched qhuav / ceev: ntau dhau high teperatures lossis ntau dhau kev ua kom nrawm nrawm thaum lub suab nrov hauv sab hauv, tsim kev ntxhov siab tag nrho.
Mismatched txheej ceev thiab slurry theem nce qib: cov slurry theem nkag mus rau hauv theem ziab ua ntej nws tau ua tiav, ua rau tsis muaj qhov nro.
3. Cov teeb meem uas tam sim no
Tsis txaus sab roughness: tus sau nyiaj tam sim no (tooj liab / txhuas ntawv ci) nto dhau lawm, ua rau cov tsis zoo slurry adhing thiab yooj yim.
Cov khoom sib kis tau lossis oxidation: roj, txheej oxide, lossis cov kev tsis sib haum xeeb ntawm cov chaw sau ua ke tam sim no cuam tshuam rau cov slurry's adhesion.
Tsis ncaj ncees lub factor tam sim no: kev hloov pauv ntawm cov neeg sib tham tam sim no thaum lub sijhawm tswj tau muaj peev xwm ua rau muaj kev sib dhos hauv zej zog lossis zaws.
4. Cov txheej txheem tsis zoo kom qhuav
Tsis muaj kev siv tshuab tua: tsis muaj kev siv classic kom qhuav (piv txwv li, stildrated kub ntxiv) ua rau muaj kev nrawm nrawm nrawm nrawm.
Tsis xwm yeem huab cua ceev: ntau dhau ntawm huab cua nrawm thaum cua ziab kom nrawm nrawm thiab ua rau cov kab nrib pleb.
5. Cov Khoom Siv thiab Kev Ua Haujlwm
Tsis zoo txheej taub hau (slitheGee) qhov tseeb: Uneven txheej qhov khoob lossis hniav hnav ua rau tsis muaj kev faib tawm sleven slurry.
Cov cuab yeej siv kev co lossis substrate sib txawv: kev co tshuab kev co lossis substrate sib txawv tuaj yeem ua rau txheej tuab.
Kev daws teeb meem thiab cov tswv yim txhim kho
1. Slurry formulation opulation
Hloov cov ntsiab lus cov ntsiab lus: tsim nyog ua kom cov ntsiab lus khib nyiab (piv txwv li 60% -70%) kom txo qis kev ntxhov siab.
Txhim kho cov phau ntawv tuav:
Ua kom nce cov ntawv sib xws (piv txwv li, nce PVDF los ntawm 2% rau 3% -4%).
Siv cov ntawv sib dhos (piv txwv, CMC + SBR) txhawm rau txhim kho qhov yooj.
Txhim kho cov neeg sawv cev coj ua haujlwm: kom muaj kev faib tawm ntawm cov neeg coj ua xws li pob milling thiab siab {} ceev dispersing.
Ntxiv cov tshuab yas lossis cov chaw ntub dej: txhim kho slurry rheology thiab wettability (piv txwv li, peg, surfactants).
2. Txheej Txheem Txuas Mus Zoo
Controlling Coating Thickness: The recommended single-sided coating thickness is<=150μm. Yog hais tias txheej txheej tuab tuab yog tuab heev, siv ntau lub tsho loj.
Gradient Kom Qhuav Chaw:
Hauv qhov qis - kub cheeb tsam (50-80 degree), maj mam yaj kom tsis txhob muaj tawv nqaij saum npoo.
Hauv nruab nrab - high - kub cheeb tsam (80-120℃li qhov kub kom ntseeg tau cov kuab tshuaj ntxiv.
Kho cov txheej ceev: kom ntseeg tau tias cov slurry muaj sijhawm txaus rau qib (piv txwv li, txo cov txheej ceev txheej ceev lossis ntxiv ib ntu ntu).
Acey - hfc250Tsis siv neeg zaj duab xis txheej tshuabRau roj teeb electing txheej nyob rau hauv kev tshawb fawb ntawm ntau qhov siab {{0} txheej duab yeeb yaj kiab, cov khoom siv roj teeb cov duab, thiab cov duab roj teeb tshwj xeeb; Lawv tuaj yeem hloov kho kom haum rau kev txhim kho kev tshawb fawb thiab thev naus laus zis rau zaj duab xis tsim raws cov kev mob siab rau yav tom ntej.
3. Tam sim no cov neeg sau khoom tseem ceeb
(Yuav luag txhua lub Lithium roj teeb cov tuam txhab tsis ua txoj haujlwm no; tawm rau nws cov chaw tsim khoom cuav.)
Kev npau taws saum npoo: Electrochemically lossis ntshav -}}} • Kho cov neeg sau ntawv tam sim no txhawm rau txhim kho qhov chaw roughness.
Kev tu thiab ziab: Tshem tawm cov roj thiab oxides (piv txwv li, acid ntxuav, machining ntxuav).
Preheat The Fullorial tam sim no: Preheat mus rau 50-80℃ua ntej txheej kom txo thermal kev ntxhov siab ntawm slurry thiab substrate.
4. Cov Khoom Siv thiab Txhim Kho Kev Ua Haujlwm
Ua cov txheej txheem ib txwm muaj txij nkawm: Txheeb xyuas cov kev sib txuam ntawm cov kab sib tshuam kom tiv thaiv hniav hnav lossis txhaws.
Ruaj khov rau substrate nro: Siv ib qho kaw - voj nro tswj cov kab ke kom txo qis substrate kev hloov pauv. Ua kom zoo qhov ziab cua Flowing: Ua kom muaj kev faib cov cua kub kub kom tsis txhob muaj cov zos tshaj- tshuab.
5. Lwm yam kev ntsuas
Kev tswj cov av noo: Saib xyuas cov av noo nyob rau hauv lub txheej sib tw ntawm 30% thiab 50% (siab}}}}}}}}}}}}}} absor electr}}} illsbing noo noo thiab nqus cov dej noo thiab ua kom qhuav sai.
Slurry kev laus: Tso cai rau slurry sawv ntsug rau 1-2 teev ua ntej txheej kom tshem tawm cov xyoob ntoo thiab kev ntxhov siab.
Kev Tswj Xyuas Online: Siv cov beta {{next} duab ci los yog laser thickness gauge mus saib txheej txheej tuab thiab kho cov txheej txheem kom sai.
Teeb meem kev kuaj mob
Kev soj ntsuam kev ua ntej: tsom xam cov pob zeb morphology (piv txwv li, transverse / ntsug nrib pleb, network tawg) siv lub tsom iav lossis lub sem.
Slurry Kev Kuaj: Kuaj slurry viscosity, cov ntsiab lus khib nyiab, thiab rheological cov khoom.
Txheej Txheem Kev Ntsuas Xyuas Dua: Kev tshuaj xyuas kom qhuav txias, txheej ceev, thiab substrate cov ntaub ntawv tsis tseem ceeb.
Adhesion kuaj: Soj ntsuam cov kev sib koom ua kom muaj zog ntawm txheej thiab tus neeg sau khoom tam sim no siv daim kab xev peel xeem. Los ntawm cov txheej txheem systemicticy cov txheej txheem, cov txheej txheem tsis sib xws, cov chaw nyob tshwj xeeb, thiab cov teeb meem ib puag ncig, txhim kho electrode tawm thiab roj teeb ua haujlwm.
Yog lawm, cov cuab yeej zoo, tsim qauv zoo, thiab cov tswv yim tshaj lij thiab cov tswv cuab muaj feem ntau ua kom tau zoo heev.
