Vim li cas cov khoom ci zoo dua tshaj li tooj liab rau cov catrede cov neeg sau khoom tam sim no hauv cov roj teeb lithium-ion?
Aluminum foil is favored due to its lightweight properties (2.7 g/cm³ vs. copper's 8.96 g/cm³), significantly reducing battery weight for applications like electric vehicles. Its natural oxide layer (2-5nm thick) provides corrosion resistance at high cathode potentials (up rau 4 {{{{{}} 5v vs {{14} Kuv tsis muaj dab tsi / /35 ms / m), nws muaj peev xwm qis dua (~35 ms Tus nqi-ua tau zoo (Txhuas yog ~30% pheej yig dua tooj liab dua li tooj liab) ntxiv tsav nws cov kev saws me nyuam. Ib qho ntxiv, cov khoom pov thawj txhuas zoo dua tshuaj sib haum nrog cov khoom siv cathhod zoo li NMC thiab LFP.
2. Dab tsi yog qhov kev sib tw corrosion loj rau txhuas ntawv ci rau hauv high-voltage roj teeb?
Localized pitting corrosion occurs in LiPF₆-based electrolytes at voltages >4 {. 2v, txheej roj teeb tsis ruaj khov, nrawm}}}}}}}}}}} Corrosion khoom nce interfacial tsis kam, txo lub neej tshiab los ntawm li 25v ntawv tshiab ua txuas ntxiv mus rau kev txo cov corrosion tam sim no ceev ntawm 90%.
3. Yuav ua li cas ua Rege hloov kho txhim kho txhuas ntawv ci?
Cov pa roj carbon monoxide carbon (50-200}} hydroxilic tsis kam ua rau cov khoom siv hluav taws xob ua kom muaj zog rau cov unettity rau underding rau unting. Graphene-armored foils qhia 91% kev muaj peev xwm khaws cia tom qab 950 mus rau hauv cov ntawv ci (pani}}} pa}}}
4. Dab tsi yog cov tseem ceeb tsim cov kev tsim khoom rau roj teeb-qib aluminium ntawv ci?
Thickness yuav tsum tau tswj tsis pub dhau ± 0 {} {{{{{{120-180 mpa mpa) thiab elongation (ntau dua tshaj li lossis sib npaug rau 1 {13.} 5%) yog qhov tseem ceeb rau yob-rau-yob ua.
