Nyob rau hauv pem hauv ntej kab ntawm lithium roj teeb ntau lawm, daim ntawv thov ntawm carbon nanotube (CNT) conductive muab tshuaj txhuam yog feem ntau nrog los ntawm ntau yam "persistent thiab nyuaj-rau- kho cov teeb meem": raws li cov mis nyuj precisely, tsis tau cov muab tshuaj txhuam hloov mus rau hauv ib tug gel-zoo li lub xeev thiab siv tsis tau; Tom qab txheej txheej, daim ntawv electrode tso cov hmoov ntawm me ntsis kov; Thaum lub sij hawm sieving, lub ntxaij lim dej clogs nquag... Cov txheej txheem no tsis tsuas yog cuam tshuam rau kev tsim khoom tab sis kuj cuam tshuam ncaj qha rau roj teeb kev ua tau zoo thiab tawm los.
Raws li pem hauv ntej -kab engineering xyaum, tsab xov xwm no muab cov lus qhia daws teeb meem ua tiav rau peb qhov siab - zaus tsis ua haujlwm -viscosity rebound, electrode sheet hmoov shedding, thiab filtration nyuaj-los ntawm kev tsom xam rau kev daws teeb meem.
1. Ua tsis tiav 1: Muab tshuaj txhuam Viscosity Rebound, tshwm gel-Zoo li
1.1 Failure Phenomenon
Thaum lub sij hawm npaj ntawm CNT conductive muab tshuaj txhuam los yog nws tov nrog active cov ntaub ntawv, cov muab tshuaj txhuam viscosity dheev thiab txawv txav, tshwm sim "gel{0}}zoo li" los yog "curd-zoo li," poob fluidity. Qhov tshwm sim no tuaj yeem tshwm sim tam sim ntawd thaum lub sijhawm sib xyaw lossis tom qab muab tshuaj txhuam tau tso cai rau sawv ntsug rau qee lub sijhawm.
1.2 Nyob rau hauv -Qhov Kev Ntsuas Qhov Ua Tau Zoo
Ua rau 1: Kev xaiv tsis raug ntawm cov khoom tawg
CNTs muaj qhov tshwj xeeb ntawm qhov chaw siab heev (180-210 m² / g) thiab muaj zog van der Waals, ua rau lawv yooj yim rau agglomeration. Lub luag hauj lwm ntawm ib tug dispersant yog adsorb rau ntawm CNT nto thiab tiv thaiv re-agglomeration los ntawm steric hindrance los yog electrostatic repulsion.
Qhov teeb meem:Kev sib raug zoo ntawm cov dispersants sib txawv nrog ntau hom CNTs txawv heev. Polyvinylidene fluoride (PVDF) feem ntau yog siv los ua cov ntawv khi hauv cov roj-raws li cov tshuab, tab sis nws cov nyhuv dispersing ntawm CNTs yog txwv. Yog tias tsuas yog PVDF tsuas yog tso siab rau raws li cov khoom tawg, CNTs nyuaj rau kev tawg tag nrho hauv NMP, thiab cov agglomeration theem nrab tuaj yeem tshwm sim tau yooj yim nyob rau hauv qhov zoo li qub lossis qis - qhov kub thiab txias, ua rau viscosity rebound.
Ua rau 2: pH tsis txaus (rau cov dej-raws li tshuab)
Hauv dej-raws li slurries, pH muaj kev txiav txim siab ntawm cov nyhuv dispersion.

Lub viscosity rebound phenomenon yog tshwj xeeb tshaj yog pom thaum lub caij ntuj no ntau lawm los yog thaum muab tshuaj txhuam tau tso cai rau sawv ntsug ntev yam tsis nplawm.
Ua rau 4: Cov dej noo ntau dhau (rau roj-raws li tshuab)
NMP yog ib qho hnyav polar hnyav thiab yog hygroscopic heev. Thaum cov dej noo nyob rau hauv paste ntau tshaj tus qauv, dej yuav 破坏 lub adsorption txheej ntawm dispersant ntawm CNT nto thiab tej zaum yuav hnov mob nrog binders xws li PVDF, ua rau cov muab tshuaj txhuam rau gel.
1.3 Kev daws teeb meem

Rau cov roj-raws li tshuab (NMP), nws raug nquahu kom siv cov tshuaj dispersants tshwj xeeb tsis yog cia siab rau PVDF nkaus xwb. Kev lag luam kev xyaum tau ua pov thawj tias polyethylene glycol thiab polyacrylate dispersants muaj qhov cuam tshuam zoo dua ntawm CNTs. Cov tshuaj dispersant feem ntau yog 5% -20% ntawm CNT huab hwm coj.
Rau cov dej-raws li systems, qhov℃ntawm kev hloov (DS) thiab molecular hnyav ntawm CMC yog qhov tseem ceeb tsis. Siv CMC nrog DS ntawm 0.7–1.2, 配合 tus nqi tsim nyog ntawm SBR, tuaj yeem txhim kho slurry stability.
Kev daws 2: Precisely tswj pH
Cov pH ntawm dej-raws li slurries yuav tsum tswj ntawm 7.5 thiab 9.0. Qhov no tuaj yeem ua tiav los ntawm:
Ntxiv me me ntawm ammonia dej los yog lithium hydroxide los kho cov pH mus rau alkaline ntau.

Tom qab cov ntawv coated electrode qhuav hauv qhov cub, hmoov poob ntawm qhov me ntsis kov. Hmoov shedding yog hnyav ntawm cov npoo thaum slitting. Tom qab calendering, daim ntawv electrode nto qhia tau hais tias "cov khoom poob tawm" tshwm sim. Qhov no tsis tsuas yog cuam tshuam rau kev tsim khoom tab sis kuj tuaj yeem ua rau sab hauv micro- luv luv lossis muaj peev xwm lwj hauv lub roj teeb.
2.2 Nyob rau hauv -Qhov Kev Ntsuas Qhov Ntsuas
Core mechanism: Lub binder yog "robbed" los ntawm CNTs
Qhov chaw tshwj xeeb ntawm CNTs yog siab li 180-210 m² / g, uas yog 3-4 npaug ntawm cov pa roj carbon dub (kwv yees li 60 m² / g). Xws li thaj chaw loj heev txhais tau hais tias CNT nto muaj coob tus "qhov chaw adsorption."
Thaum CNTs sib xyaw nrog cov binders (xws li PVDF, SBR, CMC), qee qhov ntawm cov binder molecules tau ruaj khov adsorbed rau ntawm CNT nto, uas ua rau txo qis ntawm cov ntaub ntawv muaj txiaj ntsig tiag tiag muaj rau kev sib txuas cov khoom siv ua haujlwm. Qhov tshwm sim no hu ua "binder adsorption poob."

Kauj ruam 2:Ntxiv cov pa roj carbon dub thiab CNTs, tawg ntawm kev kub ceev (linear tshaj tawm 6-14 m / s rau 0.5-2 teev).
Kauj Ruam 3:Ntxiv cov khoom siv thiab ua kom tawg mus ntxiv (linear tshaj tawm 6-14 m / s rau 3-4 teev).
Kauj Ruam 4:Thaum kawg, ntxiv SBR, txo cov kab nrawm mus rau 2-6 m / s, thiab sib tov sib npaug.
Lub ntsiab lus tseem ceeb:SBR yuav tsum tau muab ntxiv rau hauv theem kawg kom tsis txhob muaj qhov adsorption ntau dhau los ntawm CNTs, uas yuav ua rau poob ntawm nws cov nyhuv elastic.
Kev daws 3: Siv "coated" CNTs
Qee cov neeg muag khoom muab cov khoom nto - hloov kho lossis ua ntej -coated CNT cov khoom, qhov chaw yog pre{2}}coated nrog ib txheej ntawm dispersant los yog polymer, uas yuav txo tau cov adsorption ntawm binders. Txawm hais tias tus nqi siab dua me ntsis, nws tuaj yeem daws qhov teeb meem.
