I. Vim li cas cov ntaub ntawv txheej membrane xav tau?
Hauv cov roj teeb lithium-ion roj teeb, lub membrane txoj haujlwm yog cais cov electrodes zoo thiab tsis zoo thaum tso cai rau lithium ions hla dhau.
Txawm li cas los xij, ib txwm siv polyolefin daim nyias nyias (PE / PP) muaj teeb meem loj:
· Tsis zoo siab -kub tsis kam (shrinkage pib nyob ib ncig ntawm 130 degree) → nquag mus thermal runaway
· Tsis zoo wettability → qaug zog electrolyte adsorption muaj peev xwm
· Lub voj voog tsis txaus → cuam tshuam rau lub roj teeb lub neej
Yog li ntawd, kev lag luam tau pib qhia inorganic txheej txheej, thiabnano{0}}aluminatau tshwm sim los ua ib qho kev xaiv.
II. Cov txiaj ntsig tseem ceeb ntawm Nano-Alumina
1. Zoo heev Thermal Stability (Core Safety Advantage)
Nano-alumina muaj qhov melting point tshaj 2000℃. Raws li ib tug separator txheej:
· Txhim khu kev sib cais qhov kub thiab txias tsis kam
· Inhibits separator shrinkage
· Zoo txo qhov kev pheej hmoo ntawm thermal runaway
Qhov no yog ib qho ntawm cov laj thawj tseem ceeb tshaj plaws uas nws tau dhau los ua cov khoom tseem ceeb.
2. Zoo heev Electrolyte Wettability
Nano{0}}alumina muaj:
· Siab tshwj xeeb thaj chaw
· Ntau pore qauv
Cov txiaj ntsig:
· Txhim kho electrolyte adsorption muaj peev xwm
· Accelerated ion thauj tus nqi
· Txhim kho lub roj teeb tus nqi ua haujlwm
3. Txhim kho cov cuab yeej siv zog thiab kev ruaj ntseg
Coated Separator nthuav tawm:
· Siab puncture kuj
· Muaj zog qhov ruaj khov
Zoo tiv thaiv lithium dendrites los ntawm puncturing lub separator, txhim kho kev nyab xeeb
4. Txhim kho lub neej voj voog
Nano-alumina tuaj yeem:
· Stabilize lub electrode/electrolyte interface
· Txo cov kev tawm tsam sab nraud
· Txo lub peev xwm lwj
Txhim kho roj teeb lub neej zoo heev
5. Zoo tshuaj inertness
-alumina muaj tshuaj lom neeg zoo:
· Tsis hnov mob nrog cov electrolyte Haum rau ntau lub tshuab roj teeb (lub zog / lub zog cia / cov neeg siv khoom).
Ⅲ. Vim li cas "nanoscale" tsis zoo li alumina?
Qhov sib txawv tseem ceeb nyob hauv qhov tseeb tias "scale txiav txim siab ua tau zoo":
Yam ntxwv: Ordinary alumina vs. Nano- -alumina
Qhov chaw tshwj xeeb: Tsawg vs. siab heev
Dispersibility: Nruab Nrab vs. Zoo heev
Txheej uniformity: Tsis zoo vs
Electrochemical kev ua tau zoo: Txwv vs. Zoo heev
IV. Tej yam kev thov Scenarios
· Lithium{0}}ion roj teeb cais cov ceramic txheej (PE / PP puag zaj duab xis)
· Lub zog roj teeb (EV)
· Lub zog cia roj teeb (ESS)
· High-kawg neeg siv hluav taws xob roj teeb
