MWCNT hmoov rau Conductive Slurry
Muaj qhov sib txawv ntsiag to ntawm "MWCNT hmoov" thiab "MWCNT hmoov uas ua tau zoo slurry." Thawj tus zaum hauv lub raj mis. Qhov thib ob ntub dej tawm hauv NMP hauv qis dua ib teev, tsis tawm tsam koj cov xuab zeb zeb rau ob zaug, thiab tsis tawm ntawm cov av xuab zeb uas txhaws koj lub qhov - tuag lim. Cov neeg muag khoom hmoov feem ntau yeej tsis pom cov slurry sab -lawv xa cov khoom qhuav, thiab qhov tawg ntawm lub taub hau ua rau koj qhov teeb meem.
NtawmShandong Tanfeng, peb kaw qhov sib txawv vim peb khiav ob sab ntawm lub laj kab: peb loj hlob thiab ntxuav cov hmoov, thiab peb kuj khiav peb tus kheej CNT slurry kab. Yog li thaum peb spec ib "slurry-qib" MWCNT hmoov, nws tsis yog kev kwv yees - nws yog tib lub raj geometry peb paub disperses huv si ntawm 4% cov khib nyiab hauv NMP los yog dej nrog ib tug paub qab hau dispersant.
Dab tsi "Slurry-Qib" Tiag tiag
Lub slurry -qib MWCNT hmoov yog tuned ntawm plaub axes uas generic hmoov datasheets tsis quav ntsej:
De-kev sib haum xeeb- loosely agglomerated, fluffy sau (bulk ntom 0.04-0.09 g / cm³) yog li thawj siab -shear pass yeej qhib cov bundles es tsis txhob smearing lawv.
OD tuned rau 8-15nm- nyias txaus kom ntub yooj yim, tuab txaus kom axial conductivity thiab tsis vau rau hauv SWCNT-theem dispersion ntuj raug txim.
Ntev 5-20 µm, tsis yog 30+ - ntev txaus los txuas cov khoom siv, luv txaus kom muaj sia nyob cov xuab zeb-mill/media- zeb hla tsis muaj viscosity.
Tsawg hlau + tsawg amorphous sheath- Fe/Co/Ni<30 ppm and amorphous carbon <1%, so you're not dragging catalyst grit into the electrode where it poisons the electrolyte.

Si-carbon anode slurries: slurry-qib cov raj muaj sia nyob siab- cov khoom sib xyaw yam tsis tau txiav rau hauv qhov tsis muaj txiaj ntsig.
Cov dej- ua los ntawm cov khoom siv hluav taws xob: nrog –COOH/–OH functionalization, hmoov disperses hauv dej nrog CMC/PVP- hom dispersants, tsis xav tau NMP.

Feem ntau cov hmoov nplej yeej tsis khiav lub tshuab xuab zeb. Peb ua, yog li peb cov hmoov specs tau sau rov qab los ntawm cov txiaj ntsig dispersion:
Sau passivation- nto kho tsuas yog txaus kom nres re-agglomeration nyob rau hauv lub hnab, tsis ntau npaum li dispersant tsis tuaj yeem thauj tog rau nkoj. Fluffy, anti-static, pours es tsis txhob clumps.
