Dab tsi yog qhov tseem ceeb ua haujlwm ntawm txhuas ntawv ci hauv pob khoom muag muag?
Aluminium Ntawv Nyiaj Pab ua tiav raws li cov sau ua ke tam sim no thiab tiv thaiv cov teeb meem hauv cov roj teeb pob muag muag. Nws muab hluav taws xob zoo heev thaum kev tiv thaiv cov khoom siv hluav taws xob electrolyte thiab cov dej sab sab nraud. Cov ntawv nyiaj yog tus qauv ruaj khov tsis tau cov qauv hluav taws xob tsawg heev roj teeb qhov hnyav tsis muaj kev ua tau zoo. Nws txoj kev du ceev ua kom cov uniform elctrode txheej thaum tsim khoom. Tsis tas li ntawd, txhuas lub ntuj oxide txheej txhim kho corrosion tsis kam nyob rau hauv cov chaw muaj teeb meem.
Yuav ua li cas Thickness cuam tshuam kev ua tau zoo ntawm cov roj teeb aluminium ntawv nyiaj?
Cov tuab tuab ntawm 10 {-}} 20μm, ntsuas lub zog kho zog thiab lub zog ntom ntom. Thinner ntawv ci nce lub zog cia muaj peev xwm tab sis xav kom tiv thaiv kev tiv thaiv pinhole yam. Thicker variants txhim kho kev sib cav tsis kam tab sis ntxiv qhov hnyav tsis tsim nyog. Cov tuam txhab tsim kom ua kom tuab ntawm cov roj teeb thiab kev thov yuav tsum tau ua. Advanced Dov Technicate tam sim no pab tau ultra-nyias foils (8-12μm) nrog lub zog tswj lub zog.
Dab tsi kho cov kev kho yog thov rau roj teeb aluminium ntawv nyiaj?
Cov kev kho mob ib txwm muaj xws li electrochemical etching kom nce cov npoo av rau cov adhesion zoo dua. Qee cov tuam ntxhab siv cov pa roj carbon tsho kom txo qis kev cuam tshuam. Plasma Pluas tshem tawm cov kev paug organic ua ntej cov khoom siv hluav taws xob. Qee tus hwm cov ntawv foils feature feature ceramic nanoparticle cov txheej txheem thermal stability. Cov kev kho no suav tau kev txhim kho lub voj voog thiab kev nyab xeeb.
Why is purity crucial for battery-grade aluminum foil?
Yam tsawg kawg 99.5% purity tiv thaiv undesirable electrochemical sab kev tawm tsam. Kev tsis sib xws li cov hlau lossis silicon tuaj yeem tsim cov ntsiab lus corrosion hauv zos thaum caij tsheb kauj vab. Siab - purity} Cia ruaj ntseg oxide pawg tsim. Cov roj teeb cov chaw tsim hluav taws xob feem ntau yuav tsum muaj cov ntaub ntawv pov thawj ntawv pov thawj. Txawm tias 0.1% impurities tuaj yeem cuam tshuam roj teeb li cas hauv qab lub siab {{{voltage ua haujlwm.
Ua li cas cov khoom siv txhuas ua hluav taws xob kev nyab xeeb?
Nws ductility tso cai deformation yam tsis muaj qhov tawg thaum cua sov. Cov khoom siv lub txiaj ntsig siab (660 degree) qeeb thermal runaway phem. Ntawv ci thickness yog ua tib zoo tsim los sib npaug cov khoom siv tam sim no thiab luv - Circuit Court tiv thaiv. Qee cov qauv tsim teeb tsa cov qauv perforated rau tswj tsis tau cov ntsiab lus tsis ua hauj lwm. Cov alloys ua tiav tau tsim los ua ntxiv cov nplaim roj rov qab tsis muaj kev txi.
