Graphite yog mos dub rau steel grey ntxhia uas ib txwm tshwm sim los ntawm cov metamorphism ntawm cov pob zeb uas muaj cov pa roj carbon ntau, ua rau crystalline flake graphite, nplua-grained amorphous graphite, veined lossis loj graphite.Nws yog feem ntau pom nyob rau hauv cov pob zeb metamorphic xws li crystalline limestone, shale, thiab gneiss.
Graphite pom ntau yam kev lag luam siv hauv cov roj nplua nyeem, cov roj carbon txhuam rau cov tshuab hluav taws xob, hluav taws kub retardants, thiab kev lag luam steel.Kev siv cov graphite hauv kev tsim cov roj teeb lithium-ion tau loj hlob ntau dua 20% hauv ib xyoos vim qhov nrov ntawm cov xov tooj ntawm tes, koob yees duab, laptops, cov cuab yeej hluav taws xob thiab lwm yam khoom siv nqa tau.Thaum kev lag luam tsheb tau ib txwm siv graphite rau cov pawm nres, gasket thiab clutch cov ntaub ntawv tau dhau los ua qhov tseem ceeb hauv cov tsheb fais fab (EV) roj teeb.
Graphite yog cov khoom siv anode hauv cov roj teeb thiab tsis muaj qhov hloov pauv rau nws.Kev loj hlob txuas ntxiv muaj zog hauv kev thov tsis ntev los no tau raug tsav los ntawm kev muag khoom ntawm hybrid thiab tag nrho cov hluav taws xob tsheb, nrog rau kev sib txuas lus sib txuas.
Ntau lub tseem fwv thoob plaws ntiaj teb tab tom dhau txoj cai tswjfwm rau phasing tawm sab hauv combustion engines.Automakers tam sim no phasing tawm petrol thiab diesel tsheb nyob rau hauv txaus siab ntawm tag nrho cov-hluav taws xob tsheb.Cov ntsiab lus graphite tuaj yeem ncav cuag li 10 kg hauv ib qho qauv HEV (hybrid electric tsheb) thiab mus txog 100 kg hauv lub tsheb fais fab.
Cov neeg yuav tsheb tau hloov mus rau EVs raws li qhov kev txhawj xeeb ntau zuj zus thiab ntau lub chaw them nyiaj tau tshwm sim thiab ntau qhov nyiaj pab tsoomfwv pab them nqi EVs kim dua.Qhov no yog qhov tseeb tshwj xeeb tshaj yog nyob rau hauv Norway, qhov twg tsoomfwv cov kev txhawb siab tau ua rau kev muag tsheb hluav taws xob tam sim no dhau los ntawm kev muag khoom siv hluav taws xob sab hauv.
Motor Trend magazine tshaj tawm tias lawv cia siab tias yuav muaj 20 tus qauv los ntaus lub lag luam uas twb muaj lawm, nrog rau ntau tshaj li kaum tawm cov qauv hluav taws xob tshiab los koom nrog lawv.Kev tshawb fawb lub tuam txhab IHS Markit cia siab tias yuav muaj ntau tshaj 100 lub tuam txhab tsheb yuav muab cov roj teeb hluav taws xob tsheb xaiv los ntawm 2025. Cov tsheb fais fab kev lag luam feem ntau tuaj yeem ntau dua peb npaug, raws li IHS, los ntawm 1.8 feem pua ntawm Asmeskas cov ntawv sau npe hauv 2020 txog 9 feem pua hauv 2025 thiab 15 feem pua hauv 2030. .
Txog 2.5 lab lub tsheb hluav taws xob yuav raug muag hauv 2020, ntawm 1.1 lab yuav tsim nyob rau hauv Suav teb, nce 10% los ntawm 2019, Motor Trend ntxiv.Cov ntawv tshaj tawm hais tias kev muag tsheb hluav taws xob hauv Tebchaws Europe xav tias yuav ncav cuag 19 feem pua ntawm 2025 thiab 30 feem pua los ntawm 2020.
Cov kev kwv yees muag tsheb hluav taws xob no sawv cev rau kev hloov pauv loj hauv kev tsim tsheb.Ntau tshaj li ib puas xyoo dhau los, roj av thiab hluav taws xob tsheb sib tw rau kev ua lag luam.Txawm li cas los xij, tus pheej yig, muaj zog thiab yooj yim Model T yeej qhov kev sib tw.
Tam sim no peb tab tom nyob rau ntawm kev txav mus rau lub tsheb fais fab, cov tuam txhab graphite yuav yog cov neeg tau txais txiaj ntsig tseem ceeb ntawm flake graphite ntau lawm, uas yuav xav tau ntau tshaj ob npaug los ntawm 2025 kom tau raws li qhov xav tau nce.
