Dab tsi yog cov kev tshwj xeeb tseem ceeb rau jumbo yob hauv lithium roj teeb ntau lawm?
Txheem Jumbo Rolls Ntsuas Ntsuas 1,500 {{}}} 2,200mm nyob rau hauv qhov dav nrog tub ntxhais diam hlau ntawm 150-200mm (ISO 100% zam). Qhov ntau tshaj plaws yob qhov hnyav ncav cuag txog 12-15 tons kom tsawg tshaj spicting hauv cov kab nriv tes. Nto roughness yuav tsum tau tswj ra 0.1-0.3μm thoob plaws 20-30km yob ntev. Tam sim no cov thawj coj zoo li Uacj tam sim no tsim cov khoom siv tsis muaj zog nrog tsawg dua lossis muaj sib npaug nrog 1,000m². Cov kev ntsuas no ua kom muaj kev ruaj khov tswj (<2% variation) during high-speed electrode manufacturing at 80m/min.
How does the annealing process differ for battery-grade foil rolls?
Batch annaling tshwm sim hauv hydrogenes huab cua (h₂ ntau dua los yog sib npaug nrog 8} {{10} {{11 {{}} Tiab soft softing. Tshwj xeeb cov menyuam cov rawg sov ceev ceev tswj ± 2℃kub unfiformity hla tus yob vojvoog. Cov txheej txheem txo qhov nyuaj rau 25 -}}} 35hv thaum khaws cia tensile lub zog (80-120mpa). Paub cov ntsiab lus tam sim no teeb meem Ai-powered cua sov curves uas hloov rau txhua tus yob rov qab. Qhov kev kho mob no txhim kho elongation los ntawm 30% piv rau cov ntawv ci tsis yog annealed.
Dab tsi paug tswj tau siv thaum dov slitting?
Class 1000 cleanrooms with vertical laminar flow (0.45m/s velocity) control airborne particles. Diamond-coated knives (PCD grade) generate ≤5mg/m² aluminum dust per 10,000 cuts. In-line laser cleaners remove micro-burrs (>10. Ua ntej rewinding. Tiag tiag - lub sij hawm AES (Auger Electron spectroscopy)|saib xyuas cov ntsiab lus oxygen (<0.5at%). These measures achieve slitting accuracy of ±0.05mm with edge defects <0.1% of roll length.
Vim li cas thiaj li yog tuab ua ke me me rau roj teeb ntawv nyiaj?
Ib 1% Thickness variation ua rau 1.2-} 1.8% muaj peev xwm muaj peev xwm nyob rau hauv 21700 hlwb. {- Ray Thaugnness Gauges ua tiav 0.1μm kev daws teeb meem ntawm 500 scans / thib ob. Cov kev lag luam yuav tsum tau tsawg dua lossis sib npaug rau 1.5% thickness cv (coefficient ntawm kev sib txawv) thoob plaws yob. Qee cov neeg tsim tawm hwm tam sim no ua ke x {}} tshav pluorescence nrog tshuab kev kawm mus rau nws pib siv txhua 50 /}. Qhov no precision enra - nyias thib ob.
Yuav ua li cas yog ntawv ci rolls ntim kom tiv thaiv corrosion thaum cia?
VCI (Vapor corrosion inhibitor) Films nrog 0.05 hli PE Txheej txheej tsim cov kab mob oxygen (<0.1% O₂). Desiccant units maintain RH<10% inside sealed aluminum laminate bags. Each roll undergoes nitrogen purging (O₂<50ppm) before vacuum sealing. Barcode-tracked humidity indicators (3-5% RH accuracy) are attached for quality verification. This packaging system guarantees 24-month shelf life without surface oxidation, even in coastal environments.
