Nyob rau hauv tus txheej txheem ntawm kev npaj cov pa roj carbon nanotube conductive muab tshuaj txhuam, ntau R & D cov neeg ua haujlwm ntsib teeb meem xws li txawv txav slurry viscosity, tsis sib xws dispersion, thiab loj fluctuations nyob rau hauv electrode daim ntawv sab hauv kuj. Sib nrug los ntawm cov txheej txheem dispersion thiab hnyav qhov system, lub hauv paus ua rau feem ntau yog los ntawm qhov sib txawv ntawm lub cev ntawm cov pa roj carbon nanotubes lawv tus kheej. Txoj kab uas hla, qhov ntev, thiab thaj chaw tshwj xeeb ntawm cov pa roj carbon nanotubes yog peb lub cim tseem ceeb rau kev xaiv khoom. Cov kev hloov pauv hauv txhua qhov kev ntsuas yuav muaj cov tshuaj tiv thaiv kab mob ntawm cov khoom tawg, kev ua haujlwm zoo, thiab kev hloov pauv ntawm CNT conductive paste. Hauv qab no, peb txheeb xyuas qhov cuam tshuam tshwj xeeb ntawm txhua qhov ntsuas raws li qhov tseeb ntawm cov khoom tsim tawm.
1. Carbon Nanotube Diameter txiav txim siab Slurry Dispersion nyuaj thiab kev sib cuag tiv thaiv
Qhov me me ntawm txoj kab uas hla ntawm cov pa roj carbon nanotubes, qhov zoo dua qhov intrinsic conductivity, tab sis qhov siab dua qhov kev ua haujlwm saum npoo, ua rau agglomeration ntau dua, nce dispersion nyuaj thiab system viscosity. Txoj kab uas hla loj dua yog yooj yim rau disperse, ua rau lawv haum rau formulations uas processability yog qhov tseem ceeb.
Thinner CNTs muaj tsawg dua phab ntsa, qis electron conduction tsis kam, thiab zoo heev conductive nyhuv ntawm tus nqi ntxiv. Txawm li cas los xij, van der Waals rog ntawm cov raj nyias nyias muaj zog dua. Yog hais tias txoj kev sib tsoo thiab dispersion tsis raug tswj kom zoo, lawv tuaj yeem yooj yim re-entangle, ua rau cov khoom thiab sedimentation hauv slurry. Thicker CNTs muaj qhov tsis muaj zog rau kev sib koom ua ke, muab siab dua kev sib cais ntawm NMP thiab dej-raws li tshuab, nrog slurry flowability zoo dua, haum rau loj - nplai txheej txheej.

2. Carbon Nanotube Length cuam tshuam rau Slurry Conductive Network Tsim thiab Rheological Properties
Ntev ntev carbon nanotubes yooj yim dua tsim txuas ntxiv txuas txuas txuas txuas txuas ntxiv, txo qhov kev tiv thaiv tag nrho ntawm cov slurry, tab sis lawv ua kom cov slurry viscosity nce. Shorter CNTs muab cov dej ntws zoo dua, haum rau cov txheej txheem txheej txheej nyias, tab sis lawv qhov ntev - muaj peev xwm ua tau zoo dua qub.
Ntev CNTs cia siab rau lawv ib qho - qhov ntev ntawm cov qauv los tsim kom ntev -ntau txoj hauv kev hla cov khoom. Ib qho ntxiv me me tuaj yeem ua tiav qhov tsis kam sab hauv, txuag cov nqi tsim khoom. Txawm li cas los xij, cov raj ntev ntev sib cuam tshuam los tsim cov qauv hauv network, xauv hauv cov kuab tshuaj thiab ua rau pom kev nce ntxiv hauv slurry viscosity, uas tuaj yeem ua rau muaj teeb meem xws li kev kos duab thiab cov txheej txheem tsis zoo. luv CNTs tsis yooj yim entangle nrog ib leeg, ua rau cov slurry ruaj khov rheology. Lawv feem ntau siv ua ke nrog cov raj ntev thiab cov pa roj carbon dub hauv hybrid conductive systems los sau cov khoob hauv cov khoom siv hluav taws xob.
Shandong Tanfeng tuaj yeem hloov kho CNT raw cov ntaub ntawv nrog qhov ntev sib txawv, thaum tseem tsim tiav CNT conductive muab tshuaj txhuam kom ua kom zoo dua slurry rheology thaum ua kom ntseeg tau, hloov mus rau siab - nrawm txheej txheej ntau lawm thiab daws qhov teeb meem ntawm tawm - ntawm - tswj viscosity thaum lub sij hawm tsim kev debugging.
3. Cov pa roj carbon Nanotube tshwj xeeb thaj chaw cuam tshuam rau Slurry Oil Absorption, Dispersant Dosage, thiab Interfacial Bonding
Qhov siab dua ntawm thaj chaw tshwj xeeb ntawm cov pa roj carbon nanotubes, lawv lub peev xwm los nqus cov kuab tshuaj thiab cov ntaub ntawv muaj zog dua, yuav tsum tau muaj ntau dua ntawm cov tshuaj dispersant thiab binder los npaj cov slurry. Yog tias qhov sib piv tsis sib npaug, nws tuaj yeem ua rau slurry flocculation yooj yim.
High-tshwj xeeb-surface- cheeb tsam CNTs muaj ntau qhov chaw ua haujlwm thiab ntau cov ntsiab lus sib cuag nrog cathode thiab anode cov ntaub ntawv nquag, txo qis kev sib cuag tiv thaiv thiab txhim kho roj teeb lub neej. Txawm li cas los xij, lub peev xwm adsorption muaj zog ntawm siab -surface- cheeb tsam cov raj siv ntau ntawm PVDF, CMC, thiab lwm yam binders hauv lub cev. Thaum lub binder tsis txaus, slurry stability txo, ua rau txheej txheej thiab sedimentation. Tsawg-tshwj xeeb-surface- cheeb tsam CNTs muaj qis adsorption, siab formulation kam rau ua, haus tsawg binder, thiab yooj yim rau kev ua.
