Ob-walled carbon nanotubes yog seamless hollow nanotubes tsim los ntawm curling ntawm ob txheej ntawm graphene nplooj ntawv.Nws cov qauv yog nruab nrab ntawm ib leeg-walled thiab multi-walled carbon nanotubes thiab muaj feem ntau ntawm lawv cov khoom.

DWNT tuaj yeem siv los ua cov khoom siv roj, ua cov khoom rhiab rau cov pa roj xws li H2, NH3, NO2 lossis O2, thiab lwm yam, siv rau kev thov kev siv, xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob photovoltaic.

Vim tias cov khoom siv hluav taws xob ntau dua, cov pa roj carbon nanotubes tuaj yeem ua tus neeg sawv cev hauv cov roj teeb lithium, uas yog sib npaug rau lub luag haujlwm ntawm "conductors" hauv lithium roj teeb conductive network.Cov pa roj carbon cia muaj peev xwm ntawm cov pa roj carbon nanotubes yog ntau dua li cov khoom siv carbon ib txwm muaj xws li ntuj graphite, dag graphite thiab amorphous carbon.Yog li ntawd, kev siv cov pa roj carbon nanotubes ua tus neeg sawv cev lithium roj teeb tuaj yeem ua kom muaj peev xwm thiab lub neej voj voog ntawm lithium roj teeb., Carbon nanotubes muaj hluav taws xob ob txheej txheej, uas yog qhov tsim nyog rau kev txhim kho lub roj teeb tus nqi loj thiab kev ua haujlwm tawm.Nyob rau tib lub sijhawm, cov pa roj carbon nanotubes siv hauv lithium roj teeb me me, uas tuaj yeem txo cov ntsiab lus ntawm cov khoom siv hluav taws xob hauv cov roj teeb lithium.Nws cov thermal conductivity zoo kuj yog qhov zoo rau cov cua sov dissipation thaum lub roj teeb them thiab tawm.
