1. Cov ntawv thov roj teeb lithium anode:
Tam sim no, cov khoom siv anode lag luam feem ntau yog graphite ntuj thiab graphite dag. Koob coke yooj yim rau graphitized thiab yog ib hom khoom siv graphite zoo. Tom qab graphitization, nws muaj cov qauv fibrous pom tseeb thiab cov qauv graphite microcrystalline zoo. Hauv qhov kev taw qhia ntawm cov khoom me me, nws muaj qhov zoo ntawm kev ua hluav taws xob zoo thiab thermal conductivity thiab coefficient nthuav dav thermal me me. Koob coke raug tsoo, faib ua pawg, zoo li, granulated, thiab graphitized kom tau txais cov khoom siv graphite dag, uas muaj qib siab ntawm crystallinity thiab graphitization, thiab ze rau cov qauv graphite zoo meej.
Kev lag luam tsheb fais fab tshiab tau tsim kho sai heev nyob rau xyoo tas los no. Txij lub Ib Hlis mus txog rau lub Cuaj Hlis 2022, cov roj teeb fais fab hauv kuv lub tebchaws yog 372GWh, nce ntxiv txhua xyoo ntawm 176%. Lub Koom Haum Tsheb Tuam Tshoj kwv yees tias tag nrho cov muag tsheb fais fab yuav ncav cuag 5.5 lab hauv xyoo 2022, thiab tus nqi nkag mus ntawm cov tsheb fais fab thoob plaws hauv ib xyoos yuav tshaj 5.5 lab. 20%. Cuam tshuam los ntawm "kab liab ntawm kev txwv tsis pub hlawv" thoob ntiaj teb thiab txoj cai hauv tebchaws ntawm "lub hom phiaj carbon ob npaug", kev thov thoob ntiaj teb rau cov roj teeb lithium yuav ncav cuag 3,008GWh hauv xyoo 2025, thiab kev thov rau koob coke yuav ncav cuag 4.04 lab tons.
2. Cov teb thov graphite electrode:
Koob coke yog ib yam khoom zoo rau kev tsim cov electrodes graphite siab / ultra-high power. Nws cov tsos muaj cov qauv fibrous zoo thiab qhov sib piv ntawm qhov ntev thiab qhov dav ntawm cov khoom loj. Thaum lub sijhawm extrusion molding, qhov ntev ntawm feem ntau cov khoom me me tau teeb tsa raws li kev taw qhia extrusion. Kev siv koob coke los tsim cov electrodes graphite siab / ultra-high power muaj qhov zoo ntawm kev tiv taus qis, coefficient nthuav dav thermal qis, kev tiv taus thermal poob siab muaj zog, kev siv electrode qis thiab qhov ceev ceev. Cov koob coke raws li thee thiab roj muaj lawv tus kheej cov yam ntxwv hauv kev ua tau zoo. Hauv kev sib piv ntawm kev ua tau zoo ntawm koob coke, ntxiv rau qhov tseeb qhov ceev, qhov ceev ntawm lub kais, hmoov resistivity, tshauv cov ntsiab lus, sulfur cov ntsiab lus, nitrogen cov ntsiab lus, Ntxiv rau kev sib piv ntawm cov ntsuas kev ua tau zoo ib txwm muaj xws li qhov sib piv thiab qhov loj me ntawm cov khoom me me, yuav tsum tau them sai sai rau cov coefficient thermal expansion, resistivity, compressive strength, bulk density, true density, bulk expansion, anisotropy, uninhibited state thiab Kev txheeb xyuas thiab kev soj ntsuam ntawm cov yam ntxwv xws li cov ntaub ntawv nthuav dav hauv lub xeev txwv, qhov kub thiab txias thaum nthuav dav thiab kev cog lus, thiab lwm yam. Cov yam ntxwv no tseem ceeb heev rau kev kho cov txheej txheem hauv cov txheej txheem tsim khoom ntawm graphite electrodes thiab los tswj kev ua tau zoo ntawm graphite electrodes. Tag nrho, kev ua tau zoo ntawm cov roj-raws li koob coke yog me ntsis siab dua li ntawm cov thee-raws li koob coke.
Cov lag luam carbon txawv teb chaws feem ntau xaiv cov roj zoo zoo li cov roj coke ua cov khoom siv tseem ceeb rau kev tsim cov electrodes graphite UHP thiab HP loj. Cov lag luam carbon Nyiv kuj siv qee cov thee-raws li koob coke ua cov khoom siv raw, tab sis tsuas yog rau kev tsim cov electrodes graphite nrog cov lus qhia hauv qab Φ600mm. Txawm hais tias kev tsim khoom lag luam ntawm koob coke hauv kuv lub teb chaws lig dua li cov tuam txhab txawv teb chaws, nws tau tsim kho sai sai hauv xyoo tas los no thiab tau pib tsim. Tam sim no, kuv lub teb chaws cov khoom siv hluav taws xob graphite electrode siab feem ntau yog cov koob coke ua los ntawm thee. Hauv cov nqe lus ntawm tag nrho cov khoom tsim tawm, cov chaw tsim khoom koob coke hauv tsev tuaj yeem ua tau raws li qhov xav tau ntawm cov lag luam carbon los tsim cov electrodes graphite siab / ultra-power rau koob coke. Txawm li cas los xij, tseem muaj qee qhov sib txawv piv rau cov tuam txhab txawv teb chaws hauv qhov zoo ntawm koob coke. Cov khoom siv hluav taws xob graphite electrode loj loj ultra-high-power tseem vam khom cov koob coke txawv teb chaws, tshwj xeeb tshaj yog cov pob qij txha graphite siab / ultra-power yog imported. Koob coke ua cov khoom siv raw.
Xyoo 2021, kev tsim cov hlau hauv tebchaws yuav yog 1.037 billion tons, uas yog kev tsim cov hlau hluav taws xob rauv taws xob tsawg dua 10%. Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam thiab Kev Siv Tshuab Xov Xwm tau koom tes npaj yuav nce qhov feem pua ntawm kev tsim cov hlau hluav taws xob rauv taws xob mus rau ntau dua 15% hauv xyoo 2025. Lub Koom Haum Hlau thiab Hlau Hauv Tebchaws kwv yees tias nws yuav ncav cuag 30% hauv xyoo 2050. Nws yuav ncav cuag 60% hauv xyoo 2060. Kev nce qhov feem pua ntawm kev tsim cov hlau ntawm cov hlau hluav taws xob yuav tsav tsheb ncaj qha rau qhov xav tau cov hluav taws xob graphite, thiab ntawm chav kawm, qhov xav tau cov coke koob.
