Dab tsi yog cov yam ntxwv tseem ceeb ntawm 1070 txhuas ntawv ci rau cov ntawv thov roj teeb?
1070 aluminium ntawv ci yog lub siab-huv alloy (99.7% al) nrog tsawg kawg (<0.3% trace elements), ensuring excellent electrical conductivity. Its low iron content (<0.25%) reduces electrochemical side reactions in lithium-ion batteries. The foil exhibits superior ductility, allowing thicknesses as thin as 8–15 μm without cracking. It forms a stable oxide layer for corrosion resistance, critical for cathode current collectors. These properties make it ideal for high-energy-density batteries, especially in EVs and energy storage systems.
2. Yuav ua li cas 1070 txhuas txhuas cov khoom ci piv rau lwm cov roj teeb-alloys nyiam 1235 lossis 8079?
Tsis zoo li 1235 (99.35% al) lossis 8079 (97% al), 1070 muaj kev sib npaug ntawm Purity (99.7%) thiab nqi-efficiency. Nws cov ntsiab lus silicon qis (<0.2%) minimizes brittle intermetallic phases, enhancing flexibility during electrode winding. While 8079 has better strength due to iron, 1070 provides higher conductivity for low-resistance applications. Surface treatments (e.g., coatings) adhere more uniformly to 1070 than to alloys with higher impurity levels. Manufacturers choose 1070 for mid-range performance requirements where purity and price are prioritized.
3. Yuav ua li cas txoj kev kho cov khoom sib xws rau 1070 ntawv ci los ua kom zoo dua cov roj teeb ua tau zoo?
Cov kev kho mob ib txwm muaj xws li hydrophilic txheej txhim kho Slurry Adhesion rau cov ntaub ntawv zoo li NMC lossis LFP. Electrochemical etching tsim micro-roughness (ra 0. 3 μm) rau cov kws kho tshuab zoo dua. Qee cov neeg tsim khoom siv siv cov roj carbon-raws li txheej los txo cov interfacial tsis kam. Cov kab hluav taws xob pinhole-dawb yog kom ua kom zoo los ntawm precision dov thiab kaw cov tshuab. Cov kev kho mob no sib sau ua ke ua ke lub neej thiab them \/ kev tawm haujlwm hauv roj teeb.
4. Dab tsi yog cov neeg kho tshuab yuav tsum muaj rau 1070 ntawv ci hauv kev muaj roj teeb muaj roj teeb?
Lub zog tensile yuav tsum tau ntawm 12 {{{{{{}}}}} - 160 mpa kom withstand high-ceev txheej thiab slitting txheej txheem. Elongation (ntau dua lossis sib npaug rau 2%) yog qhov tseem ceeb los tiv thaiv kev tawg thaum lub sij hawm ci winding. Thickness kam yog nruj me ntsis tswj (± 0.5 μm) kom tsis txhob muaj cov pob kub. Cov ntawv ci yuav tsum tau dhau cov qev nyiaj nruj me ntsis (piv txwv li, 180 degree cov quav tsis muaj kev sib dhos) rau cov hluav taws xob sib dhos. Cov qauv no tau ua kom haum nrog cov roj teeb sib xws.
5. Yuav ua li cas yog 1070 txhuas cov ntawv ci rov ua hauv lub roj teeb kev lag luam?
Cov ntawv qhia tom qab ntau lawm scraps tau melted thiab kho kom rov kho 99.5% + purity rau rov siv dua. Kev lees paub txog kev tshem tawm cov khoom seem ntawm cov chaw seem (piv txwv li, cov kab ke lithium) thaum rov ua dua tshiab. Siv 1070 ntawv ci ceev ~ 90% ntawm nws qhov qub uas muaj, sib tham txog cov qauv roj teeb feem ntau. Kaw-lub tshuab kaw hluav taws xob txo kev siv hluav taws xob los ntawm 85% piv rau Khab Aluminium ntau lawm. Cov roj teeb cov khoom lag luam nce ntxiv ua ke 1070 ntawv ci kom ntsib cov phiaj xwm kev ruaj khov yam tsis muaj kev ua tau zoo.
