1. Lithium roj teeb anode daim ntawv thov teb:
Tam sim no, cov khoom lag luam anode feem ntau yog ntuj graphite thiab dag graphite. Koob coke yog ib qho yooj yim rau graphitized thiab yog ib yam khoom zoo graphite raw khoom. Tom qab graphitization, nws muaj qhov pom tseeb fibrous qauv thiab zoo graphite microcrystalline qauv. Nyob rau hauv cov kev taw qhia ntawm qhov ntev axis ntawm cov hais, nws muaj qhov zoo ntawm cov hluav taws xob zoo thiab thermal conductivity thiab me me thermal expansion coefficient. Koob coke yog crushed, cais, zoo li tus, granulated, thiab graphitized kom tau cov khoom siv graphite, uas muaj qib siab ntawm crystallinity thiab graphitization, thiab nyob ze rau lub zoo meej graphite txheej txheej.
Kev lag luam tsheb hluav taws xob tshiab tau tsim kho sai hauv xyoo tas los no. Txij Lub Ib Hlis Ntuj txog Lub Cuaj Hli 2022, cov khoom tsim tawm ntawm cov roj teeb hluav taws xob hauv kuv lub tebchaws yog 372GWh, ib xyoos ib zaug nce ntawm 176%. Tuam Tshoj Automobile Association kwv yees tias tag nrho cov kev muag khoom ntawm lub tsheb fais fab yuav ncav cuag 5.5 lab nyob rau hauv 2022, thiab tus nqi nkag ntawm lub tsheb hluav taws xob thoob plaws hauv lub xyoo yuav tshaj 5.5 lab. 20%. Kev cuam tshuam los ntawm thoob ntiaj teb "kab liab ntawm kev txwv tsis pub sib xyaw" thiab txoj cai hauv tebchaws ntawm "ob lub hom phiaj carbon", lub ntiaj teb kev thov rau cov roj teeb lithium yuav tsum ncav cuag 3,008GWh hauv 2025, thiab qhov kev thov rau koob coke yuav ncav cuag 4.04 lab tons.
2. Graphite electrode daim ntawv thov teb:
Koob coke yog cov khoom siv zoo rau kev tsim khoom siab / ultra-siab zog graphite electrodes. Nws cov tsos muaj ib tug zoo-tsim fibrous kev ntxhib los mos qauv thiab ib tug loj particle ntev-dav ratio. Thaum lub sij hawm extrusion molding, ntev axis ntawm feem ntau hais yog teem raws li extrusion kev taw qhia. . Kev siv rab koob coke los tsim lub zog siab / ultra-siab graphite electrodes muaj qhov zoo ntawm qhov tsis muaj zog, tsis tshua muaj thermal expansion coefficient, muaj zog thermal shock resistance, tsawg electrode noj thiab siab tso cai tam sim no ceev. Coal-based thiab roj-based koob cokes muaj lawv tus kheej cov yam ntxwv hauv kev ua haujlwm. Nyob rau hauv kev sib piv ntawm koob coke kev ua tau zoo, ntxiv rau qhov tseeb ntom, cov hmoov tshauv, ntxiv rau cov lus qhia thiab cov khoom lag luam loj me me, kuj tau them rau lub thermal expansion coefficient, resistivity, compressive zog, bulk ntom, muaj tseeb ceev, bulk expansion, anisotropy, uninhibited lub xeev thiab kev soj ntsuam thiab ntsuam xyuas cov yam ntxwv indicators, As expansion data in the restrained state, temperature range thaum expansion thiab contraction, thiab lwm yam. Cov yam ntxwv ntsuas no tseem ceeb heev los kho cov txheej txheem tsis nyob hauv cov txheej txheem ntawm graphite electrodes thiab tswj kev ua haujlwm ntawm graphite electrodes. Ntawm tag nrho, qhov kev ua tau zoo ntawm cov roj-raws li koob coke yog me ntsis siab dua li ntawm rab koob coke.
Cov tuam txhab txawv teb chaws feem ntau xaiv cov roj zoo koob coke ua cov khoom siv tseem ceeb rau kev tsim cov khoom loj UHP thiab HP graphite electrodes. Cov tuam txhab Japanese cov tuam txhab kuj siv qee cov thee-raws li rab koob coke ua cov khoom siv raw, tab sis tsuas yog rau kev tsim cov graphite electrodes nrog cov lus qhia hauv qab Φ600mm. Txawm hais tias kev lag luam tsim cov koob coke hauv kuv lub teb chaws yog tom qab ntawm cov tuam txhab txawv teb chaws, nws tau tsim sai heev nyob rau hauv xyoo tas los no thiab tau pib ua kom zoo. Tam sim no, kuv lub teb chaws high-power graphite electrode aggregates yog cov thee-based koob coke. Nyob rau hauv cov nqe lus ntawm tag nrho cov ntau lawm, domestic koob coke ntau lawm units muaj peev xwm ua tau raws li cov kev xav tau ntawm cov tuam txhab uas muag los tsim high / ultra-power graphite electrodes rau koob coke. Txawm li cas los xij, tseem muaj qee qhov sib txawv piv nrog cov tuam txhab txawv teb chaws hauv qhov zoo ntawm koob coke. Loj-scale ultra-high-power graphite electrode raw cov ntaub ntawv tseem cia siab rau imported koob coke, tshwj xeeb tshaj yog cov high / ultra-power graphite electrode pob qij txha yog imported. Koob coke ua raw khoom.
Hauv xyoo 2021, kev tsim cov hlau hauv tsev yuav yog 1.037 billion tons, ntawm cov khoom siv hluav taws xob hluav taws xob steel ua rau tsawg dua 10%. Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam thiab Cov Ntaub Ntawv Technology tau sib koom ua ke npaj kom nce qhov kev faib ua feem ntawm cov hluav taws xob rau cov hlau ua kom ntau dua 15% hauv 2025. Lub National Iron thiab Steel Association kwv yees tias nws yuav ncav cuag 30% hauv 2050.Nws yuav ncav cuag 60% hauv 2060. Kev nce ntxiv steelmaking piv ntawm hluav taws xob rauv yuav ncaj qha tsav qhov kev thov rau graphite electrodes, thiab tau kawg, qhov kev thov rau koob coke.
