Dab tsi paub qhov txawv ob xoom (00) cov ntawv ci los ntawm cov qauv roj teeb ntawv?
Double zero foil refers to ultra-thin aluminum with thickness below 0.01mm (10μm), significantly thinner than conventional battery foils (typically 15-20μm). This extreme thinness reduces battery weight by up to 30% while maintaining necessary conductivity. The production requires precision rolling mills with automatic thickness control systems (±0.2μm tolerance). Special annealing processes prevent foil breakage during high-speed battery assembly. Despite its delicacy, 00 foil demonstrates surprising tensile strength (>100MPA) los ntawm cov qauv lis kom zoo.
Yuav ua li cas muag pob pob roj teeb tsim nyog los ntawm 00 txhuas ntawv ci?
Cov ntawv hlawv cov kev hloov kho uas haum siv hluav taws xob zoo hloov hauv cov roj muag pob muag muag thaum lub caij tsheb kauj vab. Nws cov khoom malleable qhov kev tso cai rau cov quav huv ntawm lub hnab npoo yam tsis muaj kev tawg lossis kev sib tawg. Cov khoom siv isotropic cov khoom kom ntseeg tau tias muaj kev faib tawm tam sim no thoob plaws qhov chaw siv hluav taws xob. Piv rau cov kaus poom txhav, nws ua rau 15-20% lub zog hluav taws xob ceev dua los ntawm kev sib tw sib xyaw. Cov ntawv ci dej noo kev thaiv cov khoom muaj sia (<0.1g/m²/24h WVTR) are crucial for protecting lithium chemistry in unpackaged designs.
Dab tsi kho cov kev kho cov tshuaj saum npoo txhim kho 00 ntawv ci kev ua tau zoo hauv cov roj teeb lithium?
Kev ntxuav plasma tshem tawm cov organic seem thaum nce lub zog saum npoo kom zoo dua qub txheej txheem. Nano {{{{{}} teev ceramic txheej (50 {}} kub 100nm tuab) muab rwb thaiv tsev rau ntawm cov ntawv ci kom tiv thaiv kom tsis txhob muaj luv. Cookers Carbon txheej (1-33m) tau thov kom txo cov kev cuam tshuam nrog cov ntaub ntawv nquag. Laser texturing tsim cov qauv micro-qauv (5-8μm qhov tob) uas mechanically xauv elurrries slurries. Cov kev kho no suav sib haum xeeb lub neej los ntawm 20% piv rau tsis kho ntawv ci.
Yuav ua li cas thiaj manufacturers tiv thaiv cov kab mob pinhole tsis xws luag nyob rau hauv cov ntawv puab me me?
Multi-stage filtration systems remove particles >1μm los ntawm Molten aluminia ua ntej pov. Rolling mills ua haujlwm laser scanners tshawb pom qhov tsis xws li 2μm thaum kev tsim khoom. Cov Txheej Txheem Txheeb Xyuas Txheej Txheem Rolling Dag rau hauv ± 0.5% kom tsis txhob zas tuab. Kev Siv Huv Ib puag ncig (Chav 1000) txo cov plua plav kom huv thaum muab cov ntawv tuav. Kev kuaj xyuas zaum kawg siv siab - daws CCD cov koob yees duab scanning txhua square centimeter ntawm 10μm kev daws teeb meem.
Dab tsi yog qhov tawm ntawm cov qauv hluav taws xob hauv 00 txhuas ntawv ci rau tom ntej- genter roj teeb?
Composite foils with polymer cores (eg, PET-aluminum-PET) enable sub-5μm thickness while maintaining structural integrity. SELF - Kho cov txheej txheem zoo yog tsim los kho cov micro {{} breads thaum ua haujlwm roj teeb. Alloy nrhav txhim kho lub ntiaj teb tsis tshua muaj zog xws li Lanthhanum los txhawb txoj kev ua haujlwm los ntawm 8 {}} 10%. Dov -}} rau-yob qhuav electrode cov txheej txheem tshem tawm cov kuab tshuaj uas tuaj yeem tsim kev puas ultra-nyias ntawv. Qee cov tuam ntxhab tab tom sim nrog cov qauv tsim muaj zog (5% qhib thaj chaw) los txo qhov hnyav thaum tswj txoj kev coj ua.
