Hauv kev tsim cov roj teeb lithium,roj teeb aluminium foilua hauj lwm raws li covcathode tam sim no collector, cuam tshuam ncaj qha rau txheej txheej, kev ua haujlwm hluav taws xob, thiab kev cia siab rau lub sijhawm ntev - roj teeb.
Ntawm tag nrho cov ntsuas qhov zoo,pinhole nqifeem ntau underestimated-tab sis qhov tseeb, nws yog ibtseem ceeb parameter uas cuam tshuam ncaj qha tawm los, kev nyab xeeb, thiab sib xws.

Dab tsi yog Pinhole hauv Roj Teeb Aluminium Ntawv Nyiaj?
A pinholeyog ib qho microscopic los ntawm - thickness defect nyob rau hauv txhuas ntawv ci, feem ntau tsim thaum dov los yog tshwm sim los ntawm inclusions, deg paug, los yog cov khoom inconsistencies.
Hauv roj teeb aluminium ntawv ci, pinholes feem ntau yog:
Pom tsis pom qhov muag liab qab
Pom tau los ntawmKev tshuaj xyuas lub teeb lossis cov txheej txheem hluav taws xob
Ntsuas raws lipinhole suav rau ib cheeb tsam
Txawm tias me me, pinholes tuaj yeem muajcov teebmeem tsis zoohauv kev siv roj teeb.
Vim li cas roj teeb Aluminium Ntawv Nyiaj Yuav Tsum Tau Ultra-Tus Pinhole Tsawg
2.1 Ua kom lub cev Cathode txheej
Lithium roj teeb cathode slurry xav tauuniform wetting thiab adhesionnyob rau ntawm aluminium foil nto.
Pinholes cuam tshuam slurry kis
Binder tuaj yeem nkag los ntawm qhov tsis xws luag
Cov txiaj ntsig hauvnon-coating thickness
Qhov no ua rau:
Localized txheej tsis muaj zog
Ntug peeling los yog hmoov los tom qab ziab
Txo cov txheej txheem kev ruaj ntseg ntawm siab - txheej txheej ceev
2.2 Tiv thaiv hluav taws xob thiab Electrochemical Risk
Hauv lithium - ion roj teeb, aluminium ntawv ci ua haujlwm raws li aruaj khov tam sim no collector.
Pinholes tuaj yeem qhia:
Local tam sim no ceev concentration
Micro luv- qhov kev pheej hmoo ntawm Circuit Court tom qab daim ntawv qhia hnub
Kev coj cwj pwm tsis zoo electrochemical thaum caij tsheb kauj vab
RauEV fais fab roj teeb thiab lub zog cia, txawm tias me me tsis xws luag tuaj yeem cuam tshuamntev -kev nyab xeeb thiab kev ntseeg siab.
2.3 Txhim kho roj teeb tawm los thiab kev tsim khoom ua haujlwm zoo
High pinhole tus nqi ncaj qha txo cov qoob loo ntau lawm:
Kev tsis lees paub ntau ntxiv thaum lub sijhawm tshuaj xyuas txheej
Ntau qhov teeb meem pom tom qab daim ntawv qhia hnub
Ntau dua tus nqi seem thiab cov nqi rov ua dua
Roj teeb manufacturers ua haujlwmnruam, siab - kab ceevxav tau aluminium foil nrogtsis tu ncua tsawg pinhole qibkom ruaj khov throughput.
2.4 Txhawb Cov Hluav Taws Xob Hluav Taws Xob Cov Hluav Taws Xob Hluav Taws Xob
Raws li roj teeb technology nce mus rau:
Aluminium ntawv ci (10-12 μm)
Siab zog ceev electrodes
Kev kam rau qhov tsis xws luag yuav qis dua.
Tsawg pinhole aluminium foil tsis yog xaiv tau lawm - nws yog qhov yuav tsum tau uarau - tiam tom ntej lithium roj teeb tshuab.
Kev sib raug zoo ntawm Pinhole tus nqi thiab lwm yam khoom tseem ceeb
Nws yog ib qho tseem ceeb kom paub meej tiaspinhole tus nqi yog ywj siab los ntawm kev kho degxws li tus nqi siab dyne.
| Khoom | Muaj nuj nqi | Txheej Txheem Keeb Kwm |
|---|---|---|
| Tsawg Pinhole Rate | Cov qauv kev ncaj ncees | Base foil zoo & dov |
| Tus nqi siab Dyne | Txheej adhesion | Kev kho saum npoo |
| Thickness Uniformity | Mechanical stability | Rolling & nro tswj |
| Kev huv huv | Txheej txheej | Degreasing & tuav |
Ib tus kws tshaj lij roj teeb ntawv xa khoom yuav tsumtswj tag nrho cov parameter ib txhij, tsis txhob cia siab rau kev kho deg los npog cov qauv tsis xws luag.
Dab tsi ua rau Pinholes hauv Aluminium Ntawv Nyiaj?
Cov hauv paus ntsiab lus muaj xws li:
Impurities los yog inclusions nyob rau hauv molten aluminium
Tsis yog -cov khoom siv hlau tau kaw thaum dov
Tsis zoo deg huv si ua ntej txias dov
Ntau dhau dov txo lossis tsis ruaj khov
Cov cuab yeej vibration los yog yob nto tsis xws luag
Roj teeb - qib aluminium foil xav tauntau nruj txheej txheem tswjtshaj ntim los yog muaj ntawv ci.
Yuav ua li cas roj teeb -Qib Manufacturers tswj Pinhole tus nqi
Cov tuam txhab tshaj lij siv ntau-theem tswj:
5.1 Siab -Purity Raw Materials
Siv cov roj teeb - qib aluminium ingots
Kev tswj cov tshuaj muaj pes tsawg leeg nruj (xws li . 1235, 8011 alloys)
5.2 Optimized Rolling txheej txheem
Precision txias dov nrog tswj kev txo qis
Online thickness thiab nto saib xyuas
5.3 Tswj huv huv
Roj-dawb dov ib puag ncig
Advanced degreasing thiab tu tshuab
5.4 100% Kev tshuaj xyuas Pinhole
Lub teeb tshuaj xyuas tshuab
Statistical pinhole suav tsom xam
Batch traceability
5.5 Thib Peb-Party Verification
Pinhole tshuaj xyuas thiab kev ua tau zoo tuaj yeem raug txheeb xyuas los ntawm cov koom haum ywj pheej xws liSGS, nce buyer kev ntseeg siab thiab audit npaj txhij.
Hom Pinhole Requirements rau Roj Teeb Aluminium Ntawv Nyiaj
Thaum cov kev txwv tseeb txawv ntawm cov chaw tsim khoom roj teeb, cov kev cia siab ib txwm suav nrog:
Tsis tshua muaj pinhole suav ib square meter
Tsis tas li los yog clustered pinholes
Stable pinhole kev ua tau zoo nyob rau hauv coil ntev
Ua raws li cov qauv hauv roj teeb OEM
Tsawg tus pinhole tus nqi tshwj xeeb yog qhov tseem ceeb rau:
EV fais fab roj teeb
Lub zog cia system (ESS) roj teeb
Siab - nrawm, dav - dav txheej txheej
Dab tsi cov neeg yuav khoom yuav tsum tau kuaj xyuas thaum muab cov roj teeb txhuas ntawv ci
Thaum ntsuam xyuas cov neeg muag khoom, cov neeg yuav khoom yuav tsum tsom mus rau:
Pinhole soj ntsuam txoj kev thiab zaus
Keeb kwm pinhole kev ua tau zoo sib xws
Base foil thickness thiab alloy stability
Kev huv huv thiab kev tswj qhov tsis xws luag
Quality system ua raws li, xws liISO
Tus nqi qis uas tsis muaj qhov ruaj khov pinhole tswj feem ntau ua rausiab dua downstream manufacturing nqi.
