In-depth Analysis ntawm Composite Aluminium Foil Kev Lag Luam: Industrialization Accelerates, Kev Ua Lag Luam Loj Cia Siab Tshaj Tawm 24 Billion los ntawm 2026

Hauv 2025, kev lag luam aluminium foil composite tau ntsib kev loj hlob tawg, vam meej thoob plaws tag nrho cov saw hlau los ntawm cov khoom siv rau kev siv. Qhov no tsis yog tsuas yog qhia txog qhov kev tsis pom kev ntawm kev sib xyaw aluminium ntawv ci hloov cov ntawv ci ib txwm muaj tab sis kuj qhia txog cov khoom lag luam kub hauv cov khoom siv., cov ntaub ntawv foil, thiab base films. Raws li ib tug “tshiab nyiam” yug los ntawm trillion-yuan roj teeb lag luam, dab tsi raws nraim yog tsav no kev lag luam transformation, thiab yuav ua li cas nws yuav reshape lub industrial toj roob hauv pes?

Kev Hloov Kho Tshuab: Composite Aluminium Foil daws cov tub ntxhais “Zog-kev nyab xeeb” Teeb meem nyob rau hauv cov roj teeb

Tsoos aluminium ntawv ci tau ntev tau daig hauv qhov teeb meem rau kev siv roj teeb hluav taws xob: 12μm tuab ntawv ci tsis tsuas yog tso nyiaj rau ib feem tseem ceeb ntawm qhov hnyav, cuam ​​tshuam kev txhim kho ntawm lub zog ceev, tab sis kuj, vim nws nyiam tsim cov burrs loj tom qab xuas nrig ntaus, dhau los ua qhov tseem ceeb zais kev phom sij ua rau lub roj teeb thermal khiav tawm. Aluminium ntawv ci composite, nrog nws “PET zaj duab xis + hlau aluminium txheej” Sandwich qauv, precisely tackles ob lub lag luam mob cov ntsiab lus, tawm los ua ib qho tseem ceeb ntawm kev txhim kho cov roj teeb fais fab.

(1) Cov “Lub teeb Code” rau Energy Density Enhancement

Lub teeb yuag kom zoo dua ntawm cov ntawv txhuas sib xyaw yog qhov tseem ceeb ntawm kev tsim kho dual hauv cov khoom siv thiab txheej txheem, ncaj qha tsav lub leap hauv roj teeb lub zog ceev:

• Nyias, Kev ua tau zoo dua ob npaug:8μm txhuas ntawv ci (6pwm PET + 2μm aluminium txheej) yog 58% sib dua piv rau 12μm ib txwm ntawv ci, ncaj qha boosting roj teeb lub zog ceev los ntawm 4.2%. Noj cov pa roj teeb fais fab nrog 150 Wh/kg ua piv txwv, hloov nws nrog composite aluminium ntawv ci tuaj yeem ua kom lub zog ntom ntom rau 160 Wh/kg, ho expanding qhov ntau.
• Chemical Wisdom of Material Combination:PET puag zaj duab xis muaj qhov ntom ntom nkaus xwb 1.38 g/cm³, qis dua hlau aluminium 2.7 g/cm³, muab lub teeb yuag kom zoo dua. Meanwhile, Hloov PET puag zaj duab xis tuaj yeem tiv taus 130-140 ° C siab kub, ua kom cov qauv kev ruaj ntseg thaum lub sijhawm ua haujlwm roj teeb thaum ua tiav qhov hnyav txo, tiv thaiv kev ua haujlwm degradation vim kub-kub deformation.
• Corporate Pov Thawj, Cov ntaub ntawv txhawb nqa:Cov ntaub ntawv patent los ntawm BYD qhia tau hais tias siv cov qauv sib xyaw ntawm 4μm PP + 3μm aluminium ntawm ob sab, piv rau 10μm ib txwm ntawv ci, tuaj yeem ua kom cov roj teeb muaj zog ceev los ntawm 2.6%. Yog siv ua ke nrog cov ntawv ci tooj liab, lub roj teeb system zog ceev yuav boosted los ntawm 6.1%, txheeb xyuas qhov muaj peev xwm loj ntawm cov ntawv txhuas sib xyaw rau kev txhim kho lub zog ntom ntom.
• Technological Breakthroughs, Kev txo nqi thiab kev txhim kho kev ua tau zoo:Cov tuam txhab xws li Shanghai Lianjing tau ua tiav kev txo nqi thiab kev nyab xeeb hloov kho rau cov ntawv txhuas sib xyaw los ntawm peb qhov kev tsim kho thev naus laus zis.: functional film modification technology, high-temperature kub xovxwm lamination txheej txheem, thiab ultra-thin aluminium foil dov tshuab, ntxiv txhawb nws cov kev coj ua lag luam.

(2) Cov “Thermal Fuse Mechanism” rau kev txhim kho kev nyab xeeb

Lub zog roj teeb kev nyab xeeb yog cov kab hauv qab rau kev txhim kho kev lag luam. Composite aluminium ntawv ci, los ntawm nws cov qauv tsim tshwj xeeb, tsim kom muaj dual “nquag + passive” kev tiv thaiv, zoo kawg nkaus ua tau raws li kev lag luam kev nyab xeeb kev xav tau:

• Txhaum Tiv Thaiv, Micro-level Innovation:Punctures nyob rau hauv ib txwm ntawv ci tsim burrs mus txog millimeter-scale, yooj yim ua rau sab hauv luv circuits. Cov hlau txhuas txheej hauv cov ntawv ci sib xyaw tsuas yog kwv yees li 1μm. Thaum ib tug puncture luv Circuit Court tshwm sim, cov hlau txheej melts sai heev zoo li fuse, tsim ib “point tawg” uas zoo txwv tsis pub luv-circuit kis tam sim no, txo thermal runaway txaus ntshai ntawm qhov chaw.
• Active tiv thaiv tiv thaiv Thermal Runaway:Polymer substrate (E.G., Xuas, PP) Nyob rau hauv cov ntaub ntawv txhuas txhuas melts thiab shrinks nyob ib ncig ntawm 150 ° C, nquag txiav tawm sab hauv tam sim no Circuit Court, ua kom muaj kev cuam tshuam ntxov hauv thermal runaway. Cov ntawv ci niaj hnub tsis muaj qhov kev tiv thaiv kev ua haujlwm, cia siab rau txoj kev passive nkaus xwb xws li nce thickness, uas txi lub zog ceev.
• Txoj Cai Tsav, Kev thov ua qhov tseem ceeb:Txoj cai tshiab EU ECE R100.03 tau siv rau lub Cuaj Hli 2025 ntxiv 10 kev ntsuam xyuas kev nyab xeeb, suav nrog hluav taws tsis kam thiab mechanical shock, ho nce qhov chaw nyab xeeb rau cov roj teeb fais fab. Nrog nws txoj kev nyab xeeb zoo heev, composite aluminium foil tau dhau los ua cov kev daws teeb meem tseem ceeb rau cov tuam txhab kom ua tau raws li cov cai tshiab, ntxiv unleashing kev lag luam xav tau.
