Cov pa roj carbon nanotubes yog cov cylindrical molecules tsim los ntawm dov ib txheej lossis ntau txheej carbon atomic nplooj (graphene), thiab yog ib qho khoom siv quantum nrog cov qauv tshwj xeeb. Yog li ntawd, cov pa roj carbon nanotubes lawv tus kheej muaj ntau yam khoom tseem ceeb thiab kev ua tau zoo ntawm graphene, uas txiav txim siab lawv txoj kev loj hlob tseem ceeb hauv kev ua haujlwm ntawm physics, chemistry, thiab cov ntaub ntawv tshawb fawb.
Nrog rau kev loj hlob ntawm lithium-ion roj teeb tshiab lub zog tsheb hauv Suav teb, cov pa roj carbon nanotubes tau qhib lawv qhov tseem ceeb tshaj plaws kev lag luam loj daim ntawv thov - ultra-high performance conductive agents rau lithium-ion roj teeb. Qhov no yog cov khoom siv los daws cov teeb meem kev ua haujlwm tseem ceeb ntawm cov roj teeb lithium-ion, xws li lub zog txuag hluav taws xob, roj teeb lub neej, kev them ceev ceev thiab kev tso tawm, thiab lub neej voj voog. Vim nws cov yam ntxwv ntawm cov khoom siv tshwj xeeb, nws tau dhau ntawm daim ntawv thov kev txwv ntawm cov ntaub ntawv uas twb muaj lawm thiab tsis tuaj yeem hloov pauv. Kev nce qib ntawm ntau pua mus rau txhiab tons tau daws cov teeb meem tseem ceeb ntawm kev paub txog cov khoom siv tshiab, txheej txheem thev naus laus zis, kev sib piv cov cuab yeej, thiab cov qauv kev ua haujlwm tseem ceeb rau kev txhim kho tag nrho kev lag luam. Cov pa roj carbon nanotubes yog cov pa roj carbon monoxide cov ntaub ntawv tawm ntawm lub sijhawm pheej hmoo tshaj plaws hauv lawv lub neej, nkag mus rau lub sijhawm loj hlob, thiab maj mam ua kom pom kev lag luam muaj txiaj ntsig ntau billions.
Cov pa roj carbon nanotubes, ua ib qho ntawm nees nkaum feem ntau cov ntaub ntawv tshiab thiab tsuas yog tus thawj coj hauv kev tshawb fawb cov ntaub ntawv carbon raws li cov ntaub ntawv, muaj cov khoom siv hluav taws xob zoo heev, txhua yam, thiab cov khoom cua sov ua cov khoom siv nano. Lawv tau maj mam qhib cov ntawv thov dav dav hauv cov haujlwm xws li cov ntaub ntawv thev naus laus zis, kev tshawb fawb txog lub neej, cov ntaub ntawv sib xyaw tshiab, aerospace, thiab lub zog. Raws li kev tshawb fawb thiab kev kwv yees los ntawm Lithium Battery Research Institute (GGII), lub ntiaj teb kev thov rau carbon nanotube conductive paste (uas muaj 3-5}% carbon nanotubes thiab tus so yog hnyav NMP) yuav tuav ib qho kev loj hlob txhua xyoo ntawm 40.8. % hauv tsib xyoos tom ntej no. Qhov kev thov yuav ncav cuag 120000 tons hauv 2022 thiab 190600 tons hauv 2023. Kev ua lag luam hauv tsev rau cov pa roj carbon nanotube conductive cov neeg ua haujlwm yuav tsum ncav cuag 4.5 billion yuan los ntawm 2025, nrog rau kev loj hlob sai ntawm lub zog roj teeb kev lag luam.
Nrog rau kev nthuav dav ntawm cov thev naus laus zis tshiab xws li cov nickel zoo electrodes, silicon-raws li tsis zoo electrodes, thiab cov roj teeb hauv lub xeev cov roj teeb lithium, daim ntawv thov ntawm cov pa roj carbon nanotubes yuav muaj kev loj hlob tawg, thiab nws yuav dhau los ua kev lag luam txhua xyoo muaj nqis billions hauv thaj teb. ntawm lithium roj teeb ib leeg. Daim ntawv thov ntawm cov khoom siv hluav taws xob hauv cov roj teeb lithium tsuas yog qhov kawg ntawm cov dej khov hauv kev lag luam ntawm carbon nanotubes, thiab yog thawj kauj ruam hauv kev lag luam paub txog cov pa roj carbon nanotubes. Cov pa roj carbon nanotubes yuav muaj kev lag luam thoob plaws hauv cov ntxaij vab tshaus, transistors, biomedicine, hnub ci photovoltaic hlwb, log tsheb, roj hlwb, xa tshuaj, hydrogen cia, polymer cov ntaub ntawv, capacitors, composite cov ntaub ntawv, thiab lwm yam., thiab yuav txuas ntxiv mus ua txhaum ntau billions. kev lag luam, tsim kom muaj kev lag luam nrog kev lag luam billions.
Txawm li cas los xij, tam sim no muaj qee cov tuam txhab lag luam hauv Suav teb uas tuaj yeem ntsuas qhov kev npaj ntawm ntau lub phab ntsa carbon nanotubes, thiab tag nrho cov khoom siv tsawg, uas txwv tsis pub siv cov pa roj carbon nanotubes ntawm qhov loj. Ntawm lawv, Gaoteli Carbon yeej ib txwm ua raws li kev tshawb fawb kev lag luam thiab txhim khu kev lag luam txhim khu kev lag luam, maj mam txhawb kev siv cov pa roj carbon nanotubes hauv ntau daim ntawv thov. Tam sim no, nws tau dhau los ua lub hauv paus loj tshaj plaws ntawm ntau cov phab ntsa carbon nanotubes hauv tsev thiab thoob ntiaj teb, thiab tseem yog cov khoom siv tshiab nrog ntau yam ua tiav ntawm cov pa roj carbon nanotubes thiab cov ntawv thov siv dav tshaj plaws.
