Alumina yog ib qho ntawm cov khoom siv dav tshaj plaws thiab siv dav tshaj plaws. Koj tuaj yeem pom nws txhua qhov chaw. Yuav kom ua tiav qhov no, kev ua tau zoo heev ntawm alumina nws tus kheej thiab tus nqi tsim khoom qis dua yog cov neeg pab tseem ceeb.
Nov yog qhov qhia txog kuj yog ib daim ntawv thov tseem ceeb heev ntawmalumina hmoov, uas yog, txheej roj teeb lithium diaphragm. Diaphragm ua ib qho tseem ceeb ntawm roj teeb lithium-ion, tuaj yeem zam kev sib cuag zoo thiab tsis zoo thiab txhawb nqa lithium ion shuttle ntawm cov electrodes, txiav txim siab qhov ua tau zoo thiab kev nyab xeeb ntawm lub roj teeb. Cov diaphragm polyolefin ib txwm muaj qhov melting point qis thiab tsis ruaj khov ntawm qhov kub siab, uas cuam tshuam loj heev rau kev nyab xeeb ntawm lub roj teeb, tam sim no inorganic ultrafine hmoov txheej lossis composite hloov kho polymer yog ib txoj hauv kev zoo los txhim kho qhov thermal stability ntawm diaphragm.
Yuav kom txhim kho qhov ua tau zoo ntawm cov roj teeb lithium separators hauv qhov kub siab, cov khoom me me ntawm aluminium oxide tuaj yeem raug coated rau ntawm qhov chaw ntawm polyolefin separators nrog kev pab los ntawm cov polymer binders. Alumina feem ntau ua lub luag haujlwm ntawm kev tiv taus kub siab, thiab tuaj yeem tswj tau qhov kev ncaj ncees ntawm lub diaphragm txawm tias nyob rau qhov kub siab ntawm 180 ° C. Tsis tas li ntawd, nws kuj tseem ua rau cov HF dawb hauv electrolyte tsis ua haujlwm kom txhim kho qhov kev tiv thaiv acid thiab kev nyab xeeb ntawm lub roj teeb; nws tuaj yeem tsim cov kua khov hauv lub roj teeb lithium los txhim kho qhov muaj peev xwm ntawm tus nqi thiab kev ua haujlwm ntawm lub voj voog, muaj qhov zoo ntawm kev ntub dej, thiab muaj qee yam kev nqus dej thiab kev khaws cia kua, thiab lwm yam.
Hais txog kev siv, cov roj teeb lithium uas muaj alumina coated tau txais kev nyiam los ntawm ntau tus thawj coj hauv kev lag luam. Cov tuam txhab xws li Sanyo, LG, thiab Maxell tau siv cov roj teeb uas muaj alumina coated los txhim kho kev nyab xeeb ntawm lub roj teeb.
Zhengzhou Xinli Wear-Resistant Materials Co., Ltd. tuaj yeem muabalumina hmoovrau ntau yam lub hom phiaj. Txais tos kom tso ib qho kev txiav txim rau kev sab laj.
