Graphite Siv Hauv Kev Siv Hluav Taws Xob

Graphene yog cov kws tshawb fawb thiab cov kws tsim qauv hu ua ib txheej ntawm graphite ntawm qib atomic, thiab cov txheej nyias ntawm graphene tau muab dov thiab siv rau hauv nanotubes.Qhov no yuav yog vim qhov ua tau zoo ntawm hluav taws xob conductivity thiab cov khoom siv tshwj xeeb lub zog thiab nruj.

Niaj hnub no cov pa roj carbon nanotubes tau tsim nrog qhov ntev-rau-qhov sib piv txog li 132,000,000: 1, uas yog qhov loj dua li lwm yam khoom siv.Dhau li ntawm siv nyob rau hauv nanotechnology, uas yog tseem tshiab nyob rau hauv lub ntiaj teb no ntawm semiconductors, nws yuav tsum tau muab sau tseg tias feem ntau graphite manufacturers tau ua tshwj xeeb qib ntawm graphite rau lub semiconductor kev lag luam rau xyoo lawm.

2. Cov Hluav Taws Xob Hluav Taws Xob, Cov Hluav Taws Xob thiab Cov Hluav Taws Xob

Cov khoom siv carbon graphite kuj nquag siv hauv cov tshuab hluav taws xob, cov tshuab hluav taws xob, thiab cov khoom hloov pauv hauv daim ntawv ntawm cov txhuam hniav.Hauv qhov no, " txhuam" yog ib qho khoom siv uas ua haujlwm tam sim no ntawm cov xov hlau nyob ruaj khov thiab kev sib xyaw ua ke ntawm cov khoom txav, thiab nws feem ntau yog nyob rau hauv lub rotating ncej.

3. Ion Implantation

Graphite tam sim no tau siv nrog ntau zaus hauv kev lag luam hluav taws xob.Nws yog siv rau hauv ion implantation, thermocouples, hluav taws xob keyboards, capacitors, transistors, thiab roj teeb ib yam nkaus.

Ion implantation yog txheej txheem engineering uas ions ntawm ib qho khoom siv tau nrawm dua hauv qhov hluav taws xob thiab cuam tshuam rau lwm yam khoom, raws li daim ntawv ntawm impregnation.Nws yog ib qho ntawm cov txheej txheem tseem ceeb siv hauv kev tsim cov microchips rau peb cov khoos phis tawj niaj hnub no, thiab graphite atoms feem ntau yog ib qho ntawm cov atoms uas tau nkag mus rau hauv cov silicon raws li microchips.

Dhau li ntawm graphite lub luag haujlwm tshwj xeeb hauv kev tsim cov microchips, graphite raws li kev tsim kho tshiab tam sim no tau siv los hloov cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob zoo ib yam.Raws li qee cov kws tshawb fawb, graphene tuaj yeem yog lwm txoj hauv kev rau silicon tag nrho.Nws yog 100 lub sij hawm nyias dua li qhov me tshaj plaws silicon transistor, ua hluav taws xob ntau dua, thiab muaj cov khoom sib txawv uas tuaj yeem pab tau zoo hauv quantum xam.Graphene kuj tau siv nyob rau hauv niaj hnub capacitors ib yam nkaus thiab.Qhov tseeb, graphene supercapacitors yog 20x lub sijhawm muaj zog dua li cov khoom siv hluav taws xob ib txwm muaj (tso tawm 20 W / cm3), thiab lawv tuaj yeem muaj 3x lub sijhawm muaj zog dua li niaj hnub no cov roj teeb lithium-ion siab.

4. Roj teeb

Thaum nws los txog rau cov roj teeb (qhuav cell thiab lithium-Ion), cov ntaub ntawv carbon thiab graphite tau ua haujlwm ntawm no ib yam nkaus.Nyob rau hauv cov ntaub ntawv ntawm ib txwm qhuav-cell (cov roj teeb peb feem ntau siv nyob rau hauv peb lub xov tooj cua, teeb nyem, remotes, thiab watches), ib tug hlau electrode los yog graphite pas nrig (lub cathode) yog surrounded los ntawm ib tug moist electrolyte muab tshuaj txhuam, thiab ob leeg yog encapsulated nyob rau hauv. ib lub tog raj kheej hlau.

Niaj hnub no cov roj teeb lithium-ion niaj hnub siv graphite ib yam nkaus - ua anode.Cov roj teeb lithium-ion qub siv cov khoom siv graphite ib txwm siv, tab sis tam sim no uas graphene tau dhau los ua tau yooj yim dua, graphene anodes tam sim no tau siv los hloov - feem ntau yog ob qho laj thawj;1. graphene anodes tuav lub zog zoo dua thiab 2. nws cog lus lub sij hawm them nqi uas yog 10x lub sij hawm sai dua li cov roj teeb lithium-ion ib txwm.

Rechargeable lithium-ion roj teeb tau dhau los ua neeg nyiam niaj hnub no.Tam sim no lawv feem ntau siv hauv peb cov khoom siv hauv tsev, khoom siv hluav taws xob, khoos phis tawj, xov tooj ntse, hybrid electric tsheb, tub rog tsheb, thiab hauv kev siv aerospace ib yam nkaus.
