Tooj liab cathode rods: Tus nqi ntawm cov roj ntsha hauv kev lag luam tooj liab cathode pas nrig suav rau 30-40% ntawm tag nrho cov nqi tsim khoom. Cov nqi roj ntuj hauv Shandong, Jiangsu, Jiangxi thiab lwm qhov chaw tau nce txij lub Kaum Hli, nrog rau tus nqi nce ntawm 40-60% / m3. Tus nqi tsim khoom ib mt ntawm cov khoom lag luam yuav nce 20-30 yuan / mt. Qhov no, suav nrog kev nce nqi ntawm kev ua haujlwm, kev tswj hwm thiab kev thauj khoom, nce tus nqi tag nrho los ntawm 80-100 yuan / mt xyoo-rau-xyoo.

Raws li SMM daim ntawv tshawb fawb, ib tug me me ntawm tooj liab pas nrig nroj tsuag 'cov nqi ua tau me ntsis nce los ntawm 10-20 yuan / mt nyob rau hauv Lub kaum hli ntuj, tab sis qhov kev txais los ntawm downstream enamelled hlau thiab cable nroj tsuag yog tsawg. Thiab tus nqi pauv tiag tiag tsis siab. Tus nqi ua ntawm tooj liab hlau tau nce rau tsuas yog qee lub tuam txhab me uas tsis muaj lub zog sib tham txog tus nqi. Rau cov nroj tsuag tooj liab, tus nqi ntawm kev txiav txim mus sij hawm ntev rau tooj liab cathode yuav nce. Feem ntau tooj liab cathode pas nrig manufacturers npaj yuav nce tus nqi ua txhua xyoo raws li kev cog lus ntev los ntawm 20-50 yuan / mt.

Copper phaj / ntawv thiab sawb: Cov txheej txheem ntau lawm ntawm tooj liab phaj / ntawv thiab sawb muaj xws li txias dov thiab kub dov. Cov txheej txheem txias dov tsuas yog siv hluav taws xob nkaus xwb, suav txog 20-25% ntawm cov nqi tsim khoom, thaum cov txheej txheem kub dov feem ntau yog siv cov roj av thiab cov hluav taws xob me me, suav txog kwv yees li 10% ntawm tag nrho cov nqi. Tom qab nce nqi hluav taws xob, tus nqi ntawm ib mt ntawm txias-kuav los tiag phaj / ntawv thiab sawb tawm tau nce 200-300 yuan / mt. Cov nyiaj tau los ntawm cov nqi hluav taws xob tau nce tus nqi ntawm cov ntawv kub dov / ntawv thiab sawb cov nroj tsuag los ntawm 30-50 yuan / mt. Raws li SMM nkag siab, tsuas yog ib qho me me ntawm cov phaj tooj liab / daim ntawv thiab cov nroj tsuag strip tau nce nqi ua haujlwm me ntsis rau ob peb tus neeg yuav khoom qis, thaum feem ntau ntawm cov nroj tsuag pom cov txiaj ntsig qis dua ntawm kev txiav txim tsis muaj zog los ntawm cov khoom siv hluav taws xob, vaj tse thiab kev lag luam txawv teb chaws.

Lub cev tooj liab:Tus nqi tsim hluav taws xob hauv kev lag luam tube tooj liab suav txog kwv yees li 30% ntawm tag nrho cov nqi tsim khoom. Tom qab qhov nce ntawm cov nqi hluav taws xob, tus nqi nce ntawm feem ntau ntawm cov tuam ntxhab. Cov nroj tsuag loj hauv tsev tooj liab tau nce lawv cov nqi ua haujlwm los ntawm 200-300 yuan / mt. Vim muaj kev lag luam siab ntawm cov tuam txhab loj, cov kev lag luam hauv qab tau raug yuam kom txais cov nqi ua ntau dua.

Copper ntawv ci:Tus nqi hluav taws xob suav nrog kwv yees li 40% ntawm tag nrho cov nqi tsim khoom hauv kev lag luam tooj liab cathode foil. Feem ntau cov nroj tsuag tooj liab tau hais tias qhov nruab nrab ntawm cov nqi hluav taws xob ntawm lub ncov thiab lub sijhawm tsis nco qab xyoo no tau nce 10-15% ntawm tib lub sijhawm xyoo tas los. Cov nqi ua ntawm tooj liab foil cov nroj tsuag muaj feem cuam tshuam nrog cov kev xav tau qis qis.

Nyob rau hauv thawj ib nrab ntawm lub xyoo, qhov kev thov tau muaj zog los ntawm cov tshiab lub zog thiab hluav taws xob kev lag luam, thiab cov nqi ua ntawm tooj liab foil nroj tsuag tau nce sharply. Raws li kev loj hlob ntawm kev xav tau qis qis hauv peb lub hlis twg, cov nqi ua haujlwm ntawm cov ntawv ci tooj liab siv hauv hluav taws xob circuits tsis tau hloov ntau. Lithium roj teeb tooj liab ntawv ci manufacturers tau kho cov nqi ua haujlwm rau qee lub tuam txhab roj teeb uas tau thov kom haum rau qhov dav ntawm cov ntawv ci.

Hlau thiab cable:Tus nqi hluav taws xob hauv kev lag luam hlau thiab cable suav txog li 10-15% ntawm tag nrho cov nqi tsim khoom. Tag nrho cov kev sib koom ua ke ntawm Tuam Tshoj txoj kev lag luam hlau thiab cable yog qhov tsawg, thiab muaj qhov hnyav dhau. Tus nqi ua haujlwm tseem nyob ntawm 10% ntawm tag nrho cov nqi khoom txhua xyoo. Txawm hais tias tus nqi ntawm kev ua haujlwm, cov khoom siv, kev tswj hwm thiab kev thauj mus los tau nce siab, nws nyuaj rau cov nqi ntawm cov khoom siv hlau thiab cable ua raws li kev nplua. Yog li ntawd, cov nyiaj tau los ntawm cov lag luam yog eroded.

Ib qho teeb meem tshwm sim hauv kev lag luam vaj tse xyoo no, thiab kev pheej hmoo ntawm peev nyiaj tau nce ntxiv. Feem ntau cov tuam txhab xaim thiab cable tau ceev faj ntau dua rau kev lees txais kev txiav txim vaj tsev, thiab tsis kam lees txais cov xaj los ntawm kev lag luam vaj tsev nrog lub sijhawm ntev thiab muaj kev pheej hmoo siab ntawm kev them nyiaj. Lub caij no, qhov kev thov hauv kev lag luam vaj tsev tsis muaj zog, uas tseem yuav cuam tshuam rau kev ua haujlwm ntawm tooj liab cathode qws nroj tsuag.

Enamelled hlau:Kev siv hluav taws xob ntawm cov nroj tsuag loj enamelled hlau siv tooj liab cathode los tsim cov khoom tiav suav rau 20-30% ntawm tag nrho cov nqi tsim khoom, thaum cov nqi hluav taws xob ntawm enamelled hlau nroj tsuag uas ncaj qha siv tooj liab xaim nyiaj rau ib feem me me. Raws li SMM nkag siab, cov kua roj vanish tso nyiaj rau 40% ntawm tag nrho cov nqi tsim khoom, thiab tus nqi volatility muaj kev cuam tshuam zoo rau cov nqi tsim khoom ntawm enamelled hlau. Tus nqi ntawm cov kua roj vanish insulating tau nce ntau xyoo no, tab sis feem ntau cov tuam txhab hauv kev lag luam enamelled hlau tsis tau hked lawv cov nqi nyob rau hauv lub ntsej muag ntawm tus nqi nce siab ntawm cov kua roj vanish. Cov khoom lag luam tshaj tawm thiab kev xav tau tsis muaj zog tau txwv cov nqi ua ntawm enamelled hlau los ntawm kev nce.
