Alumina yog ib qho ntawm cov khoom siv dav siv thiab siv ntau yam.Koj tuaj yeem pom nws nyob txhua qhov chaw.Txhawm rau ua tiav qhov no, kev ua tau zoo ntawm alumina nws tus kheej thiab tus nqi tsim khoom qis yog cov tseem ceeb.
Ntawm no los qhia kuj yog ib qho tseem ceeb heev daim ntawv thov ntawmalumina hmoov, uas yog, lithium roj teeb diaphragm txheej.Diaphragm ua ib qho tseem ceeb ntawm lithium-ion roj teeb, tuaj yeem zam kev sib cuag zoo thiab tsis zoo thiab txhawb nqa lithium ion shuttle ntawm cov electrodes, txiav txim siab kev ua haujlwm thiab kev nyab xeeb ntawm lub roj teeb.Cov tsoos polyolefin diaphragm muaj qhov qis melting point thiab tsis muaj kev ruaj ntseg ntawm qhov kub thiab txias, uas cuam tshuam rau kev nyab xeeb ntawm lub roj teeb, tam sim no inorganic ultrafine hmoov txheej los yog sib xyaw hloov polymer yog ib txoj hauv kev zoo los txhim kho thermal stability ntawm lub diaphragm.
Txhawm rau txhim kho qhov ua tau zoo ntawm qhov kub thiab txias ntawm lithium roj teeb cais, aluminium oxide hais tuaj yeem coated rau saum npoo ntawm polyolefin separators nrog kev pab ntawm polymer binders.Alumina tsuas yog ua kom zoo dua ntawm qhov kub thiab txias, thiab tuaj yeem tswj tau qhov kev ncaj ncees ntawm lub diaphragm txawm tias qhov kub ntawm 180 ° C.Tsis tas li ntawd, nws kuj neutralizes dawb HF nyob rau hauv lub electrolyte los txhim kho cov kua qaub tiv thaiv thiab kev nyab xeeb kev ua tau zoo ntawm lub roj teeb;Nws tuaj yeem tsim cov khoom siv hauv cov roj teeb lithium txhawm rau txhim kho tus nqi muaj peev xwm thiab kev ua haujlwm ntawm lub voj voog, muaj kev ntub dej zoo, thiab muaj qee yam kua dej nqus thiab ua kua dej, thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, alumina-coated lithium roj teeb cais yog nyiam los ntawm ntau tus thawj coj hauv kev lag luam.Cov tuam txhab xws li Sanyo, LG, thiab Maxell tau txais tag nrho cov alumina-coated separators los txhim kho cov roj teeb kev nyab xeeb.
Zhengzhou Xinli Hnav-Resistant Materials Co., Ltd. tuaj yeem muabalumina hmoovrau ntau lub hom phiaj.Txais tos kom muab qhov kev txiav txim rau kev sab laj.
