Aluminium Foils rau Lithium Ion roj teeb: Siab-Kev ua tau zoo rau kev cia hluav taws xob

Aluminium foils ua haujlwm raws li cov pob txha ntawm lithium ion roj teeb kev tsim kho, feem ntau ua haujlwm li cathode tam sim no cov khoom siv thiab cov pob muag muag. Crafted los ntawm siab -purity 1xxx series alloys (1060, 1070, 1100) nrog txhuas cov ntsiab lus xws li 99.00% mus rau 99.70%, cov foils no yog engineered los sib npaug hluav taws xob conductivity, ductility, thiab tshuaj stability -peb tsis yog -negotiable roj teeb kev ua tau zoo. Muaj nyob rau hauv gauges los ntawm 0.006mm (ob xoom) mus rau 0.05mm thiab tempers xws li O (tag nrho annealed) thiab H18 (tag nrho nyuaj), lawv ua raws li cov qauv thoob ntiaj teb xws li ASTM B209, EN 573-3, thiab IEC 62133. Trusted los ntawm peb cov khoom siv hluav taws xob siv hluav taws xob thoob ntiaj teb thiab cov khoom siv hluav taws xob wearables rau hluav taws xob tsheb (EVs) thiab loj-scale zog cia systems (ESS).

Kev tsim cov ntawv txhuas txhuas rau cov roj teeb lithium ion yog qhov tseeb -cov txheej txheem tsom mus rau kev tswj hwm purity thiab kev kho kom zoo. Peb pib nrog hwm 1xxx series txhuas ingots, nruj me ntsis txwv impurities (hlau tsawg dua los yog sib npaug rau 0.70%, silicon Tsawg dua los yog sib npaug rau 0.20%) kom tsis txhob brittleness thiab xyuas kom meej conductivity. Cov ingots tau txais homogenization ntawm 430-470℃kom tshem tawm cov kev ntxhov siab sab hauv, ib kauj ruam tseem ceeb rau kev tiv thaiv kev tawg thaum lub caij txias. Los ntawm ntau-dhau precision dov- mus txog 20+ kis rau ultra-thin ob xoom foils- peb ua tiav cov phiaj ntsuas ntsuas thaum tuav cov tuab tuab tuab. Tom qab- dov, tempering yog haum rau cov kev xav tau ntawm daim ntawv thov: tag nrho annealing (370{19}}420℃) kom yooj yim tshaj plaws hauv cov pob mos, los yog ua hauj lwm hardening rau txhim kho rigidity nyob rau hauv EV roj teeb collectors. Ob -theem tu txheej txheem txo cov roj seem kom qis dua 1.5mg / m², nrog rau kev xaiv los tiv thaiv corrosion txheej los yog ob-sided lub teeb (DSL) ua tiav los txhawb kev sib raug zoo nrog electrolytes thiab sealing films.

Core Performance Cwj Pwm

Peb lithium ion roj teeb aluminium foils sawv tawm rau lawv lub peev xwm ua tau raws li qhov tshwj xeeb xav tau ntawm kev siv lub zog cia. Cov yam ntxwv tseem ceeb muaj xws li:

1. Optimized hluav taws xob conductivity

Nrog rau conductivity xws li 55% mus rau 62% IACS (nyob ntawm cov qib alloy), cov foils ua kom muaj hluav taws xob hloov mus thoob cov roj teeb cathodes. Qhov no txo ​​qis kev tiv thaiv sab hauv, txo lub zog poob thaum lub sij hawm them nqi - paug tawm mus thiab txuas ntxiv roj teeb lub neej mus rau 2000+ cycles rau cov qauv qib, thiab 3000+ cycles rau siab -purity 1070 variants. Rau EV thiab ESS roj teeb, qhov no txhais tau hais tias kev tsav tsheb ntev dua thiab kev ua haujlwm ruaj khov ntawm daim phiaj.

2. Kev ua kom zoo dua qub & kev siv tshuab muaj zog

Tag nrho annealed (O temper) foils muab elongation Ntau dua los yog sib npaug li 20% (txog 28% rau ob chav xoom), ua kom tsis muaj seamless slitting, sib sau, thiab winding -txawm ntawm ultra- nyias 0.006mm gauge. Qhov kev hloov pauv no yog qhov zoo tagnrho rau cov roj teeb pob mos thiab cov khoom siv nkhaus tsim. Ua haujlwm- tawv tawv (H18) foils muab lub zog tensile ntau dua (160-190MPa), tiv thaiv kev sib tsoo thaum lub sij hawm kub ceev electrode txheej thiab EV roj teeb pob sib dhos. Ob qho kev hloov pauv tswj kev ua haujlwm ncaj ncees raws li kev rov ua dua thiab kev ntxhov siab ntawm kev siv tshuab.

3. Kev ruaj ntseg tshuaj zoo tshaj

High-purity aluminium muaj pes tsawg leeg thiab nruj impurity tswj xyuas kom zoo heev compatibility nrog lithium ion roj teeb electrolytes. Cov foils tiv taus pitting corrosion thiab tsis txhob muaj cov tshuaj lom neeg tsis xav tau, tiv thaiv kev tsim cov khoom tsim teeb meem uas degrades roj teeb. Lub ultra-huv nto (roj residue<1.5mg/m²) eliminates contamination risks, meeting the strict hygiene requirements of battery production.

4. Tight Dimensional Precision

Advanced dov tshuab ua kom cov thickness kam rau ua kom nruj li ± 0.0005μm rau ob chav xoom foils thiab ± 0.3μm rau cov qauv ntsuas. Transverse thickness fluctuation (CV tus nqi<0.6%) and minimal pinholes (≤1 pinhole/m², down to 0.3 for premium grades) guarantee uniform electrode coating and sealing. This precision ensures batch-to-batch consistency, critical for high-volume battery manufacturing.

5. Ntau yam Customization rau ntau yam kev siv

Los ntawm ultra-nyias ob lub xoom foils (0.006-0.009mm) rau lub teeb yuag rau 0.03-0.05mm 1100 qib foils rau nqi- roj teeb ESS zoo, peb txiav cov ntsuas ntsuas, alloy, thiab kho qhov chaw rau cov kev xav tau tshwj xeeb. Optional anti-static, anti-corrosion, los yog conductive coatings ntxiv txhim khu kev qha nyob rau hauv tshwj xeeb ib puag ncig, xws li sab nraum zoov EV them los yog kho mob roj teeb.
