Cov laj thawj tseem ceeb rau cov roj teeb lithium siv cov txhuas plhaub tuaj yeem txheeb xyuas kom meej los ntawm cov hauv qab no, uas yog lub teeb yuag, kev tiv thaiv corrosion, zoo conductivity, kev ua haujlwm zoo, tsis tshua muaj nqi, zoo tshav kub dissipation kev ua tau zoo, thiab lwm yam.
1. Lub teeb yuag
• Tsawg ntom ntom: Qhov ntom ntawm txhuas yog li 2.7 g / cm³, uas yog qis dua cov hlau, uas yog li 7.8 g / cm³. Hauv cov khoom siv hluav taws xob uas ua raws li lub zog loj thiab lub teeb, xws li xov tooj ntawm tes, laptops, thiab tsheb fais fab, aluminium plhaub tuaj yeem txo qhov hnyav tag nrho thiab txhim kho kev ua siab ntev.
2. Corrosion kuj
• Adaptability rau high-voltage ib puag ncig: Lub zog ua hauj lwm ntawm lithium roj teeb zoo electrode cov ntaub ntawv, xws li ternary cov ntaub ntawv thiab lithium cobalt oxide, kuj siab (3.0-4.5V). Ntawm lub peev xwm no, txhuas yuav ua ib tug tuab txhuas oxide (al₂o₃) passivation zaj duab xis nyob rau saum npoo los tiv thaiv kev xeb ntxiv. Hlau yog yooj yim corroded los ntawm electrolyte nyob rau hauv siab siab, ua rau lub roj teeb kev ua tau zoo degradation los yog to.
• Electrolyte compatibility: Txhuas muaj tshuaj lom neeg ruaj khov rau cov organic electrolytes, xws li LiPF₆, thiab nws tsis yooj yim rau cov tshuaj tiv thaiv thaum siv mus ntev.
3. Kev coj ua thiab kev tsim qauv
• Kev sib txuas ntawm cov khoom siv tam sim no: Aluminium yog cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob zoo tam sim no (xws li aluminium foil). Lub plhaub txhuas tuaj yeem txuas ncaj qha mus rau qhov zoo electrode, ua kom yooj yim rau cov qauv sab hauv, txo qhov tsis kam, thiab txhim kho lub zog sib kis.
• Plhaub conductivity yuav tsum tau: Hauv qee lub roj teeb tsim, lub plhaub txhuas yog ib feem ntawm txoj kev tam sim no, xws li roj teeb cylindrical, uas muaj ob qho tib si conductivity thiab kev tiv thaiv kev ua haujlwm.
4. Kev ua haujlwm zoo
• Zoo heev ductility: Aluminium yog ib qho yooj yim rau thwj thiab ncab, thiab yog tsim rau loj-scale ntau lawm ntawm complex duab, xws li txhuas-yas films rau square thiab mos-pob roj teeb. Steel plhaub yog ib qho nyuaj rau kev ua thiab muaj cov nqi siab.
• Sealing lav: Aluminium plhaub vuam tshuab yog cov paub tab, xws li laser vuam, uas tuaj yeem muab cov electrolyte tau zoo, tiv thaiv cov dej noo thiab oxygen los ntawm invading, thiab ntev roj teeb lub neej.
5. Kev tswj cua sov
• High heat dissipation efficiency: Lub thermal conductivity ntawm txhuas (kwv yees 237 W / m·K) yog ntau dua li ntawm cov hlau (kwv yees 50 W / m·K), uas yuav pab tau lub roj teeb kom dissipate tshav kub sai sai thaum ua hauj lwm thiab txo qhov kev pheej hmoo ntawm thermal runaway.
6. Tus nqi thiab kev lag luam
• Cov khoom siv qis thiab cov nqi ua haujlwm: Cov khoom siv raw ntawm aluminium yog nruab nrab, thiab kev siv hluav taws xob tsawg, uas yog tsim rau cov khoom loj. Piv txwv li, cov ntaub ntawv xws li stainless hlau yog kim dua.
7. Tsim kev nyab xeeb
• Cov txheej txheem tiv thaiv kev ntxhov siab: Aluminium plhaub tuaj yeem tso siab rau sab hauv thiab tsis txhob tawg thaum muaj kev kub ntxhov lossis thermal khiav tawm los ntawm kev tsim cov kev nyab xeeb li qub, xws li CID flip qauv ntawm cov roj teeb cylindrical.
8. Kev lag luam kev coj ua thiab kev tsim qauv
• Aluminium plhaub tau txais kev pom zoo txij li hnub pib ntawm lithium roj teeb kev lag luam, xws li 18650 roj teeb uas Sony tau tsim nyob rau xyoo 1991, tsim cov saw hlau loj thiab cov qauv kev lag luam, ntxiv kev sib koom ua ke nws txoj haujlwm tseem ceeb.
Muaj ib txwm muaj kev zam. Hauv qee qhov xwm txheej tshwj xeeb, cov plhaub hlau kuj tau siv:
Hauv qee qhov xwm txheej uas yuav tsum muaj lub zog muaj zog heev, xws li qee lub roj teeb hluav taws xob lossis kev siv ib puag ncig huab cua, cov nickel-plated steel plhaub yuav raug siv, tab sis tus nqi yog nce qhov hnyav thiab tus nqi.
Xaus
Aluminium plhaub tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov roj teeb lithium vim lawv cov txiaj ntsig zoo xws li lub teeb yuag, kev tiv thaiv corrosion, zoo conductivity, yooj yim ua, zoo heev tshav kub dissipation thiab tus nqi qis, zoo kawg nkaus ntsuas kev ua tau zoo, kev nyab xeeb thiab kev lag luam.
