Daim ntawv thov Alumina hmoov rau Lithium cov roj teeb Separator

Nrog rau kev txhim kho kev loj hlob ntawm cov hluav taws xob tshiab, lub zog siv hluav taws xob, lub zog kev nyab xeeb thiab kev nyab xeeb ntawm lub roj teeb thiab kev nyab xeeb ntawm lub roj teeb. Nyob rau hauv xyoo tsis ntev los no, alumina Hmoov tau dhau los ua qhov kev xaiv tseem ceeb rau kev txhim kho cov khoom ua yeeb yam rau cov roj teeb lithium distance, electrolyte affinations thiab tshuab hluav taws xob.

Lub Lithium roj teeb separator nyob nruab nrab ntawm qhov zoo thiab tsis zoo electrodes, thiab nws cov haujlwm tseem ceeb muaj:

• Kev rho tawm ntawm lub cev: tiv thaiv cov hluav taws xob zoo thiab tsis zoo los ntawm kev sib tham ncaj qha thiab ua rau muaj kev luv luv ntawm Circuit Court.

• Ion Conduction: Cia lithium ions kom dhau dawb do kom paub tseeb tias txoj haujlwm ua haujlwm ntawm lub roj teeb .

• Kev Tiv Thaiv Thermal: tswj kev ruaj ntseg qauv nyob hauv qhov chaw kub kom tiv thaiv cua sov .

Txawm hais tias ib txwm polyolefas septers muaj cov tshuaj ruaj khov thiab tus nqi qis, lawv tseem muaj teeb meem hauv qab no:

• Cov kev kub siab tsis zoo: PE / PP yuav yaj thiab ntsws ntawm 130 ~ 160 degree, ua rau cov roj teeb luv hluav taws xob.

• Tsis muaj peev txheej electrolyte wettity wettable: cuam tshuam ion kis kev ua tau zoo thiab nce sab hauv kev tiv thaiv {}}

• Muaj zog dua zog: nws yog qhov nyuaj rau kev loj hlob ntawm Lithium Dendrites thiab muaj kev pheej hmoo ntawm puncture {}}

Daws: coating nto ntawm tus separator nrog high-purity alumina hmoov tuaj yeem txhim kho cov teeb meem saum toj no.

(1) Txhim kho thermal stability - kub tiv thaiv txheej tiv thaiv txheej

• Lub ntsiab lus melting ntawm alumina yog siab npaum li 2050 degree, uas yog ntau dua li PE / PP .

• Thaum kub siab, cov alumina txheej ua ib pob txha pob txha txhav txhav kom inhibit shrinkage ntawm tus separator .

• Kev tiv thaiv tau zoo ntawm kev khiav tawm ntawm lub roj teeb thiab txhim kho kev nyab xeeb .

(2) Optimized electrolyte wettability - Txhim Kho Ion Thauj

• Lub deg deg ntawm alumina muaj cov pab pawg hydroxyl thiab muaj super numophilicity super, uas tuaj yeem txo lub kaum sab xis ntawm electrolyte {}}

• Nce cov ntsuas pa nqus ntawm tus separator los ntawm 20% ~ 30%, txo cov nqi sab hauv, thiab txhim kho kev ua haujlwm ceev.

(3) Txhim Kho Cov Mechanical Zog - Anti-Dendritic Puncture

• Nano-alumina muaj lub hardness siab, thiab puncture lub zog ntawm tus separator tom qab txheej yog nce los ntawm 50% ~ 100%.

• Ua kom zoo ua kom zoo lithium dendrite thiab txuas lub roj teeb ntev .

(4) Kev ruaj khov hluav taws xob ruaj khov - muaj kev nyab xeeb thiab ntev-ntev

• ruaj khov tshaj li ntau dua ntau ntau yam thiab tsis koom nrog hauv cov kev tsis txaus siab .

• Nws tuaj yeem nqus cov tshuaj zoo xws li HF hauv electrolyte thiab txo cov electrolyte thiab txo cov electridroid .

(1) Roj teeb hluav taws xob (cov tsheb hluav taws xob, cov cuab yeej hluav taws xob)

Cov tseev kom muaj: Kev nyab xeeb nyab xeeb thiab kub ua rau .

(2) Lub zog cia cov roj teeb (daim phiaj, tsev neeg lub zog)

• Xav tau: lub neej ntev thiab tus kheej qis .

(3) Cov Neeg Siv Khoom Siv Hluav Taws Xob (Txawb Xov Tooj, Laptops)

• Xav tau: Lub teeb thiab nyias nyias, nrawm nrawm haum siv tau}}}

(4) Cov roj teeb tshwj xeeb (kev lag luam tub rog, aerospace)

• Xav tau cov kev xav tau: kev kub ntxhov ntawm .

Alumina Hmoov, raws li txheej txheej txheem rau lithium roj teeb separators, tau dhau los ua kev lag luam lithinity, txhim kho kev lag luam lithinity, txhim kho kev lag luam lithium thiab txhawb nqa cov roj teeb lithium kev taw qhia .
