Mtengo wapamwamba kwambiri wa MWCNT Multi Walled Carbon Nanotubes
Mipikisano yokhala ndi mipanda ya CNT, ufa wa MWCNT
D: 10-30nm / 30-60nm / 60-100nm
L: 1-2um / 5-20um
Mawonekedwe a ufa wakuda
Ubwino:
Kwambiri conductive, mkulu chiyero 99%
Gawo la mafakitale
Mukayitanitsa kwambiri, mtengo wake ndi wabwino.
Sinthani makonda anu ntchito:
COOH Imagwira ntchito;OH Ntchito;Kumwazika kwa Madzi;Mafuta a masamba;Nickel-Coated Carbon Nanotubes Ngati mukuyang'ana MWCNT yamtengo wotsika, komanso ufa wochepa wa MWCNT ufa 93% -95% ulipo.
Kugwiritsa ntchito carbon nanotubes zakuthupi:
Mpweya nanotubes ndi mtundu watsopano wa zinthu conductive wothandizira, amene angathe kusintha madutsidwe wa zinthu zabwino elekitirodi yogwira kuposa wothandizira chikhalidwe conductive.Ndi yabwino kwambiri lithiamu batire conductive wothandizira.Masiku ano, omwe amagwiritsidwa ntchito kwambiri pa mabatire a lithiamu-ion makamaka akuphatikizapo mpweya wakuda, conductive graphite, carbon nanotubes, carbon nanofibers, ndi graphene.Mpweya wakuda ndi conductive graphite ndi chikhalidwe conductive wothandizira, amene amapanga mfundo-kukhudzana conductive maukonde pakati pa zipangizo yogwira;carbon nanotubes, ulusi wa carbon ndi graphene ndi zipangizo zatsopano conductive, mmene mpweya nanotubes ndi mpweya ulusi pakati pa yogwira zipangizo A mzere kukhudzana conductive maukonde aumbike, ndi graphene amapanga pamwamba-kukhudzana conductive maukonde pakati pa zipangizo yogwira.Mzere kukhudzana mtundu ndi pamwamba kukhudzana mtundu akhoza mokwanira kumanga maukonde conductive, amene akhoza mwachionekere bwino ntchito ya zinthu cathode The madutsidwe wa zinthu, potero kuchepetsa kuchuluka kwa conductive wothandizira anawonjezera zabwino elekitirodi zakuthupi.Nthawi zambiri, kuwonjezera kuchuluka kwa mpweya wakuda conductive wothandizira mu cathode zinthu zambiri pafupifupi 3%, pamene kuwonjezera kuchuluka kwa conductive wothandizira watsopano monga mpweya nanotubes ndi graphene akhoza kuchepetsedwa pafupifupi 0.5% ~ 1.0%, amene bwino kudzazidwa. za cathode yogwira ntchito.Kuchuluka kwa mphamvu kumatha kuthandizira kuchulukitsa mphamvu zamabatire a lithiamu-ion.Mapulasitiki opangira mapulasitiki: kugwiritsidwa ntchito komweko kwa ma conductive a carbon nanotubes, osakanikirana ndi mapulasitiki a uinjiniya akhoza Kupangidwa ndi pulasitiki yopangira madulidwe ndi mawonekedwe apulasitiki, omwe amagwiritsidwa ntchito kwambiri mu semiconductors ndi anti-static materials Zida ndi chitetezo chamagetsi.
