Raws li cov ntaub ntawv saum toj no, peb muab cov nqi ntsuas hauv qab no: 1) Cov hniav roj teeb ntim yog li 50% siab dua li lub zog ceev.

Thaum tus nqi them tas li, qhov ntim qis dua li ntawm ib feem peb, yog li ntawd lub plhaub npog aluminium yog tsav. Pob nqi, piv txwv li 33% poob 2) Zog, khoom tsim, tsim nqi, thiab BMS poob vim cov txheej txheem optimization thiab txo qhov seem, piv txwv li 20% txo 3) ntxiv xav tias cov khoom siv raw (xws li zoo electrode, tsis zoo electrode, diaphragm, electrolyte, tooj liab foil, Methyl poob 2% ntawm cov khoom siv roj teeb), tus nqi FP poob tag nrho. 0.696 yuan / WH rau 24.

3% rau 0.527 yuan / WH. 4) Ntxiv rau kev txiav txim siab txog lub tuam txhab cov nyiaj tau los tag nrho tuaj yeem siv tau kom tau txais cov nqi muag khoom tiag tiag, raws li pom hauv daim duab 35, cov hniav roj teeb thiab CTP txoj kev yuav tsuas yog coj tus thawj coj hauv kev lag luam tsheb, txawm hais tias BYD tshaj tawm, cov hniav roj teeb txoj kev yuav ua lag luam hauv Han Txawm li cas los xij, cov tsheb lag luam tseem yuav yog ib txoj hauv kev siv.

Peb ntseeg hais tias BYD yog kev lag luam siv rau hauv peb tus kheej lub tsheb neeg nrog caij, uas yog ua txhaum los ntawm cov txheej txheem kev lag luam dav dav: cov thev naus laus zis tshiab feem ntau nce mus rau kev lag luam tsheb, thiab cov neeg caij tsheb yuav ceev faj dua. BYD siv cov roj teeb hniav ntawm nws tus kheej lub tsheb, uas yog undoubtedly nyob rau hauv lub ceev ntawm kev txhawb nqa cov neeg nrog caij tsheb. Qhov tseeb, cov hniav roj teeb thiab CTP txoj kev yog tib yam, thiab nws yog txhawm rau txo cov nqi ntxiv, thaum lub roj teeb monomer loj, thiab lithium hlau phosphate nyiam dua.

Raws li xyoo 2019, muaj ntau lub tshuab thawj-kab nroj tsuag siv CTP txoj hauv kev kom tau txais kev xeem, yog li cov cuab yeej no yuav tsum siv cov tshuab no hauv 2020. Raws li cov kev xav saum toj no, peb xam 10 meters lossis ntau dua, cov nqi roj teeb raug txo los ntawm 30%, thiab cov nqi roj teeb raug txo los ntawm 225,000 rau 158,000. Thaum tsis muaj nyiaj pab, cov nyiaj tau los tag nrho tuaj yeem khaws cia.

Peb cia siab tias 2020 phosphate&39;s tamite&39;s roj teeb yuav raug txhim kho ntxiv hauv cov tsheb lag luam. Los ntawm qhov kev xav ntawm kev nqis peev, cov dej ntws phosphite tau muab tso rau, thiab kev lag luam downstream tsheb profitability marginal txhim kho. Txij li thaum cov dej ntws ntawm tag nrho cov lithium hlau phosphate tau dhau los ntawm kev sib tsoo peb xyoos, kev lag luam concentration yog siab.

Hauv kev lag luam saw, yog tias koj ncav cuag 10 tus neeg muag khoom, nws twb tau siab heev hauv cov ntsiab lus, thiab tsuas muaj 3-4 tus neeg muag khoom ntawm cov khoom lag luam ruaj khov thib peb. Yog li peb ntseeg tias cov txiaj ntsig leadload. Tswv yim: German nano, Guoxuan high-tech, BYD thiab Yutong Bus.
