Siv Graphite Hauv Cov Ntawv Thov Electronics

Graphene yog yam uas cov kws tshawb fawb thiab cov engineers hu ua ib txheej ntawm graphite ntawm theem atomic, thiab cov txheej nyias nyias ntawm graphene no raug dov thiab siv rau hauv nanotubes. Qhov no yuav yog vim muaj kev coj hluav taws xob zoo kawg nkaus thiab cov khoom siv lub zog thiab kev tawv nqaij tshwj xeeb.

Cov pa roj carbon nanotubes niaj hnub no tau tsim los nrog qhov sib piv ntawm qhov ntev mus rau txoj kab uas hla mus txog 132,000,000: 1, uas yog qhov loj dua li lwm yam khoom siv. Dhau li ntawm kev siv hauv nanotechnology, uas tseem yog qhov tshiab hauv ntiaj teb ntawm semiconductors, nws yuav tsum tau sau tseg tias feem ntau cov chaw tsim khoom graphite tau ua cov qib tshwj xeeb ntawm graphite rau kev lag luam semiconductor tau ntau xyoo.

2. Cov Tsav Tsheb Hluav Taws Xob, Cov Generators thiab Alternators

Cov khoom siv carbon graphite kuj tseem siv ntau hauv cov tshuab hluav taws xob, cov generators, thiab cov alternators hauv daim ntawv ntawm cov txhuam carbon. Hauv qhov no, "txhuam" yog ib lub cuab yeej uas coj tam sim no ntawm cov xov hlau ruaj khov thiab kev sib xyaw ua ke ntawm cov khoom txav mus los, thiab nws feem ntau nyob hauv lub qhov tig.

3. Kev Cog Ion

Tam sim no graphite siv ntau zaus hauv kev lag luam hluav taws xob. Nws kuj siv rau hauv kev cog ion, thermocouples, electrical switches, capacitors, transistors, thiab batteries.

Kev cog cov ion yog ib qho txheej txheem engineering uas cov ions ntawm ib yam khoom tshwj xeeb raug ua kom nrawm dua hauv ib qho hluav taws xob thiab raug cuam tshuam rau lwm yam khoom, ua ib hom kev 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 cov graphite atoms feem ntau yog ib hom atoms uas tau muab tso rau hauv cov microchips raws li silicon no.

Ntxiv rau lub luag haujlwm tshwj xeeb ntawm graphite hauv kev tsim cov microchips, cov kev tsim kho tshiab raws li graphite tam sim no tau siv los hloov cov capacitors thiab transistors ib txwm muaj. Raws li qee tus kws tshawb fawb, graphene tej zaum yuav yog lwm txoj hauv kev rau silicon tag nrho. Nws yog 100 npaug nyias dua li qhov me tshaj plaws silicon transistor, ua hluav taws xob tau zoo dua, thiab muaj cov khoom txawv txawv uas tuaj yeem pab tau zoo heev hauv kev suav lej quantum. Graphene kuj tau siv rau hauv cov capacitors niaj hnub no thiab. Qhov tseeb, graphene supercapacitors tau hais tias muaj zog dua 20 npaug dua li cov capacitors ib txwm muaj (tso tawm 20 W / cm3), thiab lawv yuav muaj zog dua 3 npaug dua li cov roj teeb lithium-ion muaj zog niaj hnub no.

4. Cov roj teeb

Thaum nws los txog rau cov roj teeb (cov roj teeb qhuav thiab lithium-Ion), cov khoom siv carbon thiab graphite kuj tau ua lub luag haujlwm tseem ceeb ntawm no thiab. Hauv cov ntaub ntawv ntawm cov roj teeb qhuav ib txwm muaj (cov roj teeb uas peb feem ntau siv hauv peb lub xov tooj cua, teeb ci, chaw taws teeb, thiab cov moos), lub electrode hlau lossis graphite pas nrig (cathode) raug puag ncig los ntawm cov electrolyte paste ntub, thiab ob qho tib si raug encapsulated hauv lub tog raj kheej hlau.

Cov roj teeb lithium-ion niaj hnub no kuj siv graphite thiab - ua ib qho anode. Cov roj teeb lithium-ion qub siv cov khoom siv graphite ib txwm muaj, txawm li cas los xij tam sim no graphene tau yooj yim dua, graphene anodes tam sim no raug siv hloov - feem ntau yog vim ob qho laj thawj; 1. graphene anodes tuav lub zog zoo dua thiab 2. nws cog lus tias yuav them lub sijhawm uas yog 10 npaug sai dua li roj teeb lithium-ion ib txwm muaj.

Cov roj teeb lithium-ion uas rov them tau dua tshiab tau nrov zuj zus tuaj niaj hnub no. Lawv feem ntau siv rau hauv peb cov khoom siv hauv tsev, cov khoom siv hluav taws xob nqa tau, cov laptops, cov xov tooj ntse, cov tsheb fais fab hybrid, cov tsheb tub rog, thiab hauv cov ntawv thov aerospace.
