Cov pa roj carbon nanotube conductive paste yog cov khoom siv hluav taws xob tseem ceeb rau cov roj teeb lithium, cov khoom siv hluav taws xob, thiab cov tshuaj tiv thaiv- cov txheej txheem zoo li qub. Kev ua lag luam feem ntau muab faib ua ob pawg: ib zaug -walled carbon nanotube conductive paste thiab multi-walled carbon nanotube conductive paste. Ntau cov ntaub ntawv engineers muaj kev tsis sib haum xeeb thaum lub sij hawm tsim khoom tshiab: raws li ua ntej -pab CNT pastes, lawv puas yuav tsum xaiv ib qho - txoj kev phab ntsa lossis ntau - txoj kev phab ntsa? Ob qhov sib txawv hauv kev ua tau zoo, qhov sib ntxiv, qhov nyuaj dispersion, thiab cov nqi tsim khoom. Kab lus no, ua ke nrog cov ntaub ntawv ntsuas kev lag luam, qhia meej txog qhov sib txawv ntawm ob hom pastes, txhais lawv cov xwm txheej siv tau, thiab muab cov qauv kev xaiv ncaj qha.
1. Core Performance Differences Ntawm Ib -Walled thiab Multi-Walled Carbon Nanotube Conductive Pastes
Ib leeg-walled carbon nanotube conductive paste muaj qhov ua tau zoo dua qhov ua tau zoo thiab qis dua qhov tseem ceeb ntxiv; multi-walled carbon nanotube conductive paste muaj qhov cuam tshuam qis dua thiab cov nqi tsim khoom muaj txiaj ntsig ntau dua, ua rau nws tsim nyog rau kev lag luam loj -.
Cov qauv sib txawv txiav txim siab qhov kev ua tau zoo qab nthab: ib leeg- cov pa roj carbon nanotubes yog tsim los ntawm dov ib txheej ntawm graphene, nrog ib txoj kab uas hla ntawm 1-2 nm thiab qhov sib piv siab heev; multi-walled carbon nanotubes muaj ib tug concentric nested qauv ntawm ntau graphene txheej, nrog diameters feem ntau li ntawm 5-15 nm. Cov lus hauv qab no muab ntau qhov sib piv kab rov tav siv cov ntsuas kev lag luam hauv kev lag luam lithium roj teeb.

Cov kab ntau lawm dispersion cov cuab yeej muaj cov qauv siv cov hlaws dai uas tsis muaj siab - siv nano- dispersion units.
Raws li kev tsim khoom loj loj, Shandong Tanfeng's MWCNT conductive paste nruj me ntsis tswj cov hlau impurities Tsawg dua los yog sib npaug rau 100 ppm, thiab muaj nyob rau hauv ob series: NMP-raws li roj-raws li muab tshuaj txhuam thiab dej{3}}raws li muab tshuaj txhuam, haum rau txawv anode thiab cathode systems.
4. Peb qhov kev xaiv yuam kev kom tsis txhob muaj kev ua tau zoo thiab raug nqi ob npaug
Tsis txhob xaiv raws li "zoo lossis phem conductivity"; cov khoom siv sib raug zoo, kev siv tshuab, thiab lub sijhawm ntev - tus nqi tag nrho yuav tsum raug ntsuas ib txhij.
Qhov yuam kev 1: Xaiv SWCNT muab tshuaj txhuam qhov muag tsis pom kev vim "kev ua tau zoo dua yog qhov zoo dua."
SWCNT conductive paste muaj tus nqi siab dua. Yog hais tias cov khoom yog positioned raws li tus nqi -kev siv lub zog cia roj teeb, qhov kev ua tau zoo redundancy yuav ncaj qha nce cell manufacturing nqi nrog tsawg cov txiaj ntsig.
Qhov yuam kev 2: Ncaj nraim pub cov khoom muab tshuaj txhuam yam tsis xav txog kev sib cais dispersion.
Lub microstructure ntawm SWCNTs zoo dua. Yog hais tias cov txheej txheem dispersion tsis sib xws, ntau cov raj tseem nyob hauv agglomerated, thiab cov txiaj ntsig ntawm cov khoom siv hluav taws xob tiag tiag kuj tseem yuav phem dua li ntawm qhov zoo -dispersed MWCNT conductive paste.
Qhov yuam kev 3: Tsis quav ntsej cov kuab tshuaj sib xyaw ua ke.
Dej-raws li systems thiab NMP-raws li roj-raws li systems sib haum mus rau txawv formulation pastes. Kev sib xyaw ua ke tsis zoo tuaj yeem ua rau slurry flocculation thiab pinhole tsis xws luag hauv cov nplooj ntawv electrode.
Tswv yim debugging plan:Ua ntej thov cov qauv me me ntawm tib cov kuab tshuaj los ntawm cov chaw tsim khoom, teeb tsa gradient ntxiv rau qhov kev sib piv, thiab soj ntsuam slurry stability, electrode resistivity, thiab lub voj voog kev ua haujlwm ua ntej muab kev txiav txim loj. Shandong Tanfeng cov kws tshaj lij pab neeg tuaj yeem pab cov neeg siv khoom hauv kev tsim cov phiaj xwm sib piv kom luv R & D voj voog.
5. Cov ntsiab lus ntawm kev txiav txim siab ceev ceev
Txhais cov khoom positioning:High-kawg them ceev ceev, silicon-carbon anodes, khoom- lub xeev roj teeb → tsom rau kev ntsuas SWCNT conductive paste; lub zog cia, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob polymer ntau lawm → ua ntej MWCNT conductive muab tshuaj txhuam.
Txheeb xyuas cov kab ntau lawm dispersion khoom muaj peev xwm:Cov kab qub qub tseem ceeb tshaj MWCNT muab tshuaj; cov kab nruab nrog siab -precision nano- cov khoom siv dispersion tuaj yeem kuaj SWCNT muab tshuaj txhuam.
Txhais qhov txwv sab sauv ntawm cov nyiaj ntxiv:Yog tias tag nrho cov khoom siv hluav taws xob ntxiv yuav tsum qis dua 0.3%, sim cov tshuaj SWCNT; Yog tias 0.5% lossis ntau dua cov khoom siv hluav taws xob ntxiv tau txais, MWCNT muab tshuaj txhuam tau zoo dua tus nqi- ua tau zoo.
Paub meej txog cov kuab tshuaj:Sib txuas lus nrog cov chaw tsim khoom ua ntej rau cov dej -raws li lossis NMP-raws li cov tshuab, thiab xaiv cov txheej txheem CNT coj los ua ke.
