Pleev roj teeb hardcore armor! Kev soj ntsuam tag nrho ntawm Aluminium prismatic casing cov ntaub ntawv: kev ua tau zoo, kev siv, thiab cua qhib rau yav tom ntej

Aluminium prismatic casing core yog ua los ntawm 3-series (3003, 3004) thiab 5-series (5052) aluminium alloys, uas tau ua tiav los ntawm dov, stamping, anodizing, thiab lwm yam txheej txheem. Nws muab faib ua peb pawg: square, cylindrical, thiab mos pob aluminium plhaub. Nws qhov kev ua tau zoo yog nyob ib puag ncig peb qhov tseem ceeb ntawm "kev tiv thaiv, kev sib khi, thiab cua sov dissipation", thiab qhov tseem ceeb tsis ua raws li cov qauv kev lag luam.

Cov khoom siv aluminium alloy endows Automotive roj teeb txhuas nrog plaub qhov zoo: ua ntej, nws sib npaug lub teeb yuag thiab lub zog siab, nrog qhov ceev ntawm tsuas yog 2.7g / cm³, uas yog 40% -50% sib dua li cov plhaub hlau, txhim kho cov roj teeb lub zog ntom ntom. Nyob rau tib lub sijhawm, nws muaj lub zog tensile txaus los tiv thaiv lub ntim nthuav dav ntawm lub roj teeb ntawm tes them thiab tawm;

Qhov thib ob, nws muaj cov thermal conductivity zoo heev thiab cov cua kub dissipation, nrog rau thermal conductivity coefficient ntawm 100-200W / (m · K), uas tuaj yeem ua cov cua sov ntawm cov roj teeb ntawm tes, tsis txhob thermal tsub zuj zuj, thiab txo cov roj teeb polarization;

Thirdly, nws muaj zog sealing thiab corrosion kuj. Tom qab kev kho saum npoo, ib daim duab oxide tuab yog tsim, uas tuaj yeem cais cov dej noo, oxygen, thiab electrolyte corrosion. Lub sealing raug yog siab thiab tuaj yeem txo tus kheej tawm ntawm lub roj teeb;

Thib plaub, nws muaj cov txheej txheem ua kom muaj zog thiab tswj tau tus nqi, zoo ductility, tuaj yeem ua rau ntau yam kev qhia tshwj xeeb, ntau qhov chaw ntawm raw cov ntaub ntawv, paub tab ntau lawm technology, tus nqi qis dua stainless hlau plhaub, thiab yog tsim rau loj - teev ntau lawm.

Nyob rau tib lub sijhawm, muaj ob qhov tsis txaus ntseeg uas tuaj yeem kov yeej hauv Aluminium rooj plaub rau lub zog tshiab. Ib qho yog qhov tsis txaus siab qhov hluav taws xob tsis txaus, uas yog qhov ua rau electrochemical corrosion nyob rau hauv 800V siab -voltage roj teeb system thiab yuav tsum tau hloov kho alloy thiab txheej txheej optimization;

Qhov thib ob, qhov qis- qhov kub thiab txias yog qhov tsis zoo, thiab nws yog qhov ua rau brittleness hauv qab -20 degree, ua rau nws nyuaj rau kev hloov mus rau sab nraum zoov lub zog cia cov xwm txheej hauv cheeb tsam txias.

Aluminium prismatic casing yog cov khoom siv rau cov lithium{0}}ion roj teeb. Los ntawm 2024, lub ntiaj teb no lithium{3}}ion aluminium plhaub lag luam yuav ncav cuag 8.6 billion yuan, nrog rau kev thov nyob rau hauv lub zog tshiab sector accounting rau ntau tshaj 90% thiab qhov nruab nrab txhua xyoo kev loj hlob ntawm ntau tshaj 18%. Nws cia siab tias kev muag khoom thoob ntiaj teb yuav ncav cuag 2.455 billion US las los ntawm 2032, nrog rau kev tsom mus rau peb qhov xwm txheej loj: cov roj teeb hluav taws xob, cov khoom siv hluav taws xob siv hluav taws xob, thiab cov roj teeb lub zog.

Cov roj teeb fais fab yog qhov tseem ceeb ntawm daim ntawv thov scenario, suav txog ntau dua 65%. Lithium roj teeb txhuas cov ntaub ntawv, nrog lawv cov qauv ruaj khov thiab siv qhov chaw siab, tuav 70% ntawm lub hwj chim roj teeb kev lag luam. Cylindrical aluminium shells feem ntau yog siv rau hauv high-tawg fais fab roj teeb kom tau raws li qhov xav tau ntawm ntau hom hlwb;

Cov neeg siv khoom siv hluav taws xob hluav taws xob cov khoom siv hluav taws xob suav nyiaj ntau dua 20%, thiab Lub zog tshiab aluminium roj teeb yuav tsum tau ultra-nyias, hnav, siab-precision, feem ntau siv me me-size cylindrical txhuas plhaub, haum rau cov khoom siv nqa tau xws li xov tooj ntawm tes thiab laptops; Lub zog cia roj teeb yog qhov xwm txheej loj tshaj plaws, feem ntau siv cov square tuab phab ntsa aluminium plhaub uas tuaj yeem tiv taus ntev - lub sij hawm them thiab tso tawm ntim nthuav dav thiab tiv thaiv qhov cuam tshuam ntawm qhov chaw sab nraum zoov. Nrog rau kev loj hlob tawg ntawm lub ntiaj teb lub zog cia roj teeb xa khoom, qhov kev thov rau txhuas plhaub yuav nce ntxiv.

Cov yam ntxwv tseem ceeb ntawm Aluminium roj teeb casing yog tswj hwm plaub qhov ntev ntawm cov khoom siv, cov khoom siv kho tshuab, kev sib khi, thiab kev tiv thaiv corrosion, muab kev txhawb nqa rau cov txheej txheem optimization thiab scene adaptation. Txoj kev ua tus cwj pwm tseem ceeb ua tau raws li cov qauv kev lag luam uas cuam tshuam thiab cov kev ntsuas tshwj xeeb. Cov khoom siv thiab cov yam ntxwv muaj pes tsawg leeg yog lub hauv paus, nrog rau kev tsom mus rau kev ntsuas cov qib aluminium alloy, tshuaj lom neeg muaj pes tsawg leeg, thiab purity kom ntseeg tau tias cov ntsiab lus impurity ua tau raws li qhov xav tau thiab tsis txhob cuam tshuam rau lub zog thiab corrosion kuj;

Mechanical thiab formability characterization yog qhov tseem ceeb. Los ntawm kev sim tshuab thoob ntiaj teb, kev sim stamping, thiab lwm yam., lub zog tensile, formability, thiab hardness raug kuaj xyuas kom ntseeg tau tias Rechargeable aluminium plhaub ua tau raws li qhov yuav tsum tau ntim ntawm cov tub ntxhais, thaum tswj cov phab ntsa thickness uniformity; Cov yam ntxwv ntawm kev sib khi thiab kev tiv thaiv corrosion yog qhov kawg validation, uas ua kom ntseeg tau tias lub plhaub txhuas tsis muaj xeb, corrosion- tiv taus, thiab muaj qhov ruaj khov oxide zaj duab xis los ntawm txoj kev immersion, helium leak detection method, electrolyte immersion test, salt spray test, etc., ua tau raws li qhov yuav tsum tau muaj ntawm cov xwm txheej sib txawv.

Tam sim no, EV tsheb roj teeb plhaub kev lag luam tab tom txhim kho mus rau "cov phab ntsa nyias, siab zog, siab voltage kuj, thiab ntsuab" kev taw qhia. Nrog rau qhov muaj koob meej ntawm 800V siab- roj teeb hluav taws xob, cov khoom siv hluav taws xob- lub xeev cov roj teeb, thiab cov roj teeb muaj peev xwm loj, cov kev xav tau siab dua tau muab tso rau ntawm kev ua tau zoo ntawm aluminium plhaub, thiab plaub qhov kev tshawb fawb hotspots tsim nyog tshwj xeeb. Ib qho yog kev kho dua tshiab ntawm cov cuab yeej hloov kho alloy, kev txhim kho cov ntaub ntawv hloov kho aluminium alloy, kev txhim kho cov hluav taws xob siab thiab tsis kub tsis kam, kev ua kom pom tseeb ntawm nyias-walled aluminium shells, thiab ntxiv dag zog ntawm roj teeb lub zog ceev;

Qhov thib ob yog txhawm rau txhim kho cov txheej txheem kho saum npoo av, txhim kho cov txheej txheem anodizing thiab ceramic txheej tshiab, txhim kho corrosion kuj thiab rwb thaiv tsev kev ua tau zoo, thiab optimize ntau lawm;

Qhov thib peb yog kev sib koom ua ke molding thiab kev ua haujlwm sib koom ua ke, txhawb kev sib koom ua ke molding ntawm aluminium plhaub nrog tawg-cov pov thawj li qub thiab cov ncej, tsim cov khoom sib xyaw ua ke ntawm aluminium plhaub nrog kev sib xyaw ua kom sov thiab rwb thaiv tsev, thiab hloov mus rau siab -kawg roj teeb xav tau;

Qhov thib plaub yog ntsuab ntau lawm thiab recycling, optimizing cov txheej txheem ntau lawm los txo cov pa phem, txhawb kev rov ua dua thiab rov qab siv cov nyiaj laus lithium-ion roj teeb txhuas plhaub, ua tiav cov peev txheej rov ua dua tshiab, thiab ua raws li ob lub tswv yim carbon. Nyob rau hauv lub neej yav tom ntej, nrog rau qhov tsis tu ncua ntawm kev lag luam hluav taws xob tshiab, liab qab aluminium plhaub yuav muaj kev hloov kho dual hauv kev ua tau zoo thiab kev thov. Cov tuam txhab lag luam uas paub cov thev naus laus zis tseem ceeb yuav ua tus thawj coj hauv kev lag luam thiab txhawb nqa siab - kev txhim kho zoo hauv thaj chaw ntawm cov khoom siv roj teeb lithium.
