Thaum lub Yim Hli, CATL (Contemporary Amperex Technology Ltd.) tshaj tawm lub ntiaj teb thawj lithium hlau phosphate roj teeb uas muaj peev xwm ntawm 4C ceev them thiab scalable loj ntau lawm - Shenxing Super Charge Battery. Tsis ntev los no, ntawm Chery Technology Day qhov kev tshwm sim, Chery Automobile thiab CATL tau tshaj tawm lawv txoj kev koom tes hauv kev koom tes thiab tshaj tawm tias Shenxing Super Charge Battery yuav raug teeb tsa thawj zaug hauv Exeed Starway Era ES. Qhov kev ua tau zoo tshaj plaws lithium hlau phosphate cov khoom lag luam no tau dhau los ua qhov tseem ceeb hauv kev lag luam, overshadowing CATL tus kheej Kirin roj teeb. Vim li cas ho xaiv lithium hlau phosphate? Cia li ceev npaum li cas yog lub supercharge ceev?
● Shenxing Super Charge Battery yog dab tsi?
Raws li cov lus tshaj tawm, Shenxing Super Charge Battery yog lub ntiaj teb thawj lithium hlau phosphate roj teeb uas tuaj yeem tsim tawm loj nrog lub peev xwm 4C supercharging.
Lo lus "4C" yog hais txog lub roj teeb tus nqi them, lub ntsiab lus tam sim no txheeb ze rau lub roj teeb lub peev xwm. Piv txwv li, yog tias 1Ah roj teeb ntawm tes raug them nrog 1A tam sim no, nws tuaj yeem nkag siab yooj yim tias lub roj teeb yuav raug them tag nrho hauv ib teev hauv qhov xwm txheej no. Yog tias qhov tam sim no nce mus rau 2A lossis 2C, lub sijhawm them nyiaj yuav txo mus rau 30 feeb.
Muaj lwm cov khoom siv roj teeb hauv kev lag luam nrog cov nqi them ntawm 4C thiab txawm tias 6C lossis 8C, xws li CATL's flagship Kirin roj teeb thiab Juwan Technology's Phoenix roj teeb, ob qho tib si tuaj yeem ua tiav cov nqi them siab. Txawm li cas los xij, feem ntau cov roj teeb uas ncav cuag 4C lossis siab dua yog ua los ntawm cov khoom siv lithium ternary. Gao Huan, CTO ntawm CATL's Passenger Car Division, tau sau tseg tias qhov ua rau Shenxing Super Charge Battery sib nrug yog tias nws txhawb nqa tus nqi them ntawm lithium hlau phosphate roj teeb rau 4C.
Cov neeg muaj teeb meem thev naus laus zis siv roj teeb cov roj teeb lithaline uas piv rau cov roj teeb lithium lithium, lithium iron piv txwv thiab tsawg-kub them thiab cov kev tawm tsam tsawg. Qhov sib txawv no tshwm sim los ntawm qhov sib txawv ntawm cov haujlwm ntawm cov khoom siv cathode. Txhawm rau ua tiav cov nqi them siab nrog kev ua haujlwm zoo dua ternary lithium tsis yog qhov nyuaj nrog kev lag luam tech tam sim no. Txawm li cas los xij, thawb lithium hlau phosphate mus rau 4C lossis siab dua yog qhov txaus nyiam heev.
Yog li, cov lus nug tshwm sim: yog tias CATL twb muaj lub roj teeb Kirin, vim li cas ho pheej nrog lithium hlau phosphate? Yuav tsum tsis yog lub neej yav tom ntej ntawm cov roj teeb ua haujlwm siab yuav tsum tau pegged ntawm kev siv thev naus laus zis hauv ternary lithium? Muaj ib tug misconception ntawm no.
Hauv kev soj ntsuam ze dua, ib tus yuav pom tias cov npe thiab cov khoom lag luam uas muaj cov kab kos muag muag hauv xyoo tas los no nyiam siv lithium hlau phosphate roj teeb. Txawm hais tias ternary lithium zoo li ntau dua, lithium hlau phosphate yuav muaj txiaj ntsig ntau dua. Qhov no qhia txog vim li cas CATL tau nqis peev ntau rau hauv kev tsim cov roj teeb lithium hlau phosphate.
● Dab tsi ua rau Shenxing thiaj li 'magic'?
Cov txheej txheem them nyiaj ntawm lithium roj teeb tuaj yeem nkag siab yooj yim raws li kev thauj mus los. Cov yam tseem ceeb uas cuam tshuam rau qhov ceev ntawm kev them nqi yog qhov detachment thiab embedding ceev ntawm lithium ions los ntawm thiab rau cov electrodes, feem. CATL's ultra-electron net cathode thev naus laus zis thiab thev naus laus zis thib ob nrawm-ion nplhaib anode thev naus laus zis yog cov kev daws teeb meem zoo rau cov teeb meem no.
Lub "electrolyte" nyob nruab nrab ntawm qhov zoo thiab qhov tsis zoo electrodes yog qhov tseem ceeb ntawm cov roj teeb lithium, cuam tshuam rau nws txoj kev ruaj ntseg, kev nyab xeeb, thiab kev ua haujlwm nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias. CATL's tshiab tsim ultra-siab conductivity electrolyte mis feem ntau txo cov viscosity ntawm cov electrolyte.
Raws li peb paub, qhov loj ntawm qhov pores nyob rau hauv cov nplooj ntawv electrode tsis tsuas yog cuam tshuam rau kev nkag mus ceev ntawm lithium ions tab sis kuj muaj feem xyuam rau lub zog ceev. CATL's multi-gradient layered electrode sheet yog tsim los kom muaj qhov ntxeem tau ntawm sab saum toj thiab denser nyob rau hauv qab.
Kev ua kom sov ntawm tus kheej los ntawm kev hloov pauv sai thiab nquag ntawm cov hluav taws xob tam sim no tso cai rau cov electrode kom sov lub roj teeb tseem ceeb. Raws li tag nrho cov tub ntxhais heats li uniformly, nws ua kom ceev kub nce. Raws li txoj cai, txawm tias nyob ntawm -10 degree, lub roj teeb tuaj yeem them rau 80% hauv 30 feeb, yog li nthuav dav ntau yam kev siv roj teeb lithium hlau phosphate, txawm tias nyob rau thaj tsam qaum teb qaum teb thaum lub caij ntuj no.
Ntxiv nrog rau qhov kev hloov pauv tau hais los saum no, CATL tau ua kom zoo dua qhov tsim qauv ntawm lub roj teeb pob. Nrog rau CTP3.0 tsim yam tsis muaj kab teeb ci thiab cov phaj kawg, lub zog ntawm kev sib txuas ntawm lub roj teeb ntawm tes thiab lub plhaub tau txhim kho. Qhov kev tsim no ua kom qhov chaw ua kom haum rau hauv ntau lub roj teeb, uas lub tuam txhab hais txog kev sib koom ua ke pob.
Gao Huan, CTO ntawm CATL's Passenger Car Division, tau hais tias Shenxing Super Charge Battery muab kev paub zoo tshaj plaws txawm tias tsis muaj cov chaw nres tsheb supercharged. Piv nrog rau lwm yam khoom, nws cov nqi them tam sim no thaum them nyiaj ceev yog qhov ruaj khov dua, tuav lub zog zoo ib yam tsis muaj kev lwj ntawm 10% mus rau 95% SOC.
Hauv cov ntsiab lus, Shenxing Super Charge Battery tsis tsuas yog sawv cev rau lub tshuab hluav taws xob lithium hlau phosphate tshiab, tab sis nws kuj rov txhais dua li cas lub roj teeb lithium hlau phosphate tuaj yeem ua tau. Nrog rau nws qhov kev tsis zoo ntawm qhov kub thiab txias, nws cov nqi kom zoo dua tau ua kom zoo ntxiv.
Yog li, lo lus nug tom ntej yog, thaum twg lub roj teeb zoo kawg no yuav muaj rau kev yuav khoom? Cov thawj coj tau qhia tias lub roj teeb no yuav pib ntau lawm hauv ob lub chaw tsim khoom lag luam los ntawm qhov kawg ntawm 2023. Nws xav tias los ntawm thawj peb lub hlis twg ntawm 2024, nws yuav ncav cuag cov neeg siv khoom nrog rau Chery Exeed Starway Era ES.
Cias muab, lub tshuab no encapsulates ob hom roj teeb sib txawv - ternary lithium thiab lithium hlau phosphate - nyob rau hauv tib lub zog roj teeb. Kev cia siab rau ternary lithium kom sib npaug ntawm lub tsheb qhov ntsuas kub qis thiab kev them nyiaj ua haujlwm, lithium hlau phosphate tuaj yeem ua tau raws li qhov yuav tsum tau siv txhua hnub thiab txo cov nqi tag nrho. Thaum lub sijhawm xam phaj, peb tau nug cov lus nug txog qhov kev tsim hybrid: Shenxing Super Charge Battery puas tuaj yeem ua raws li qhov sib xyaw ua ke no?
Teb rau qhov no, Gao Huan tau luag nyav, sib qhia "hais lus" ntawm CATL txoj kev npaj khoom lag luam yav tom ntej, "Leej twg hais tias Shenxing Super Charge Battery yuav tsum tau ua los ntawm lithium hlau phosphate? Vim li cas nws tsis tuaj yeem yog ternary lithium? Cov qauv tsim tshwj xeeb rau cov xwm txheej siv tshwj xeeb? Zoo li Shenxing Super Charge rau kev lag luam tsheb? lossis lub caij ntuj no version ntawm Shenxing?
Los ntawm kev xav, tsis yog Kirin roj teeb kuj tsis tas yuav tshwj xeeb rau ternary lithium thev naus laus zis? Tej zaum nws tuaj yeem nkag siab zoo li no: Kirin thiab Shenxing yuav yog CATL ob lub ntsiab lus tseem ceeb hauv xyoo tom ntej. Kirin yog tsom rau cov qauv high-end nrog ntev-ntau thiab muaj zog xav tau, thaum Shenxing tsom rau cov nqi tsim nyog nruab nrab thiab qis-kawg cov khoom ua ke. Nyob rau hauv ob lub tshuab no, ntau hom roj teeb yuav tshwm sim, xws li "Kirin Lithium Iron Phosphate" lossis "Shenxing Ternary Lithium". Lub tswv yim meej yog xav tau los ntawm CATL.
