Roj teeb plhaub aluminium foil plays lub luag haujlwm tseem ceeb hauv kev siv roj teeb niaj hnub, tshwj xeeb tshaj yog nyob rau hauv lithium-ion roj teeb, nickel-hlau hydride roj teeb, thiab lwm yam kev ua haujlwm siab zog cia tshuab.
Qhov twg siv Aluminium Foil rau Roj Teeb Case
Aluminium ntawv nyiaj is employed in the construction of battery cases for:
- Lithium-ion roj teeb: Rau lawv lub teeb yuag, siab zog ceev, thiab yooj.
- Nickel-Metal Hydride Batteries: Muab ib qho kev xaiv zoo rau cov ntawv thov uas xav tau tus nqi tso tawm siab.
- Lwm hom roj teeb: Xws li lub hnab roj teeb thiab cov roj teeb square.
Cov ntawv ci ua ib txheej tiv thaiv nyob rau hauv lub roj teeb casing, tiv thaiv cov ingress ntawm noo noo thiab oxygen, uas tuaj yeem degrade roj teeb kev ua haujlwm dhau sijhawm.
Vim li cas thiaj siv Aluminium Ntawv Nyiaj rau Roj Teeb Case?
- Corrosion Resistance: Aluminium ib txwm tsim ib txheej oxide, muab zoo heev tiv thaiv corrosion, uas yog ib qho tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm rooj plaub roj teeb.
- Kev coj ua: Aluminium lub siab hluav taws xob conductivity ua kom muaj txiaj ntsig zoo tam sim no, txhim khu kev ua haujlwm roj teeb.
- Lub teeb thiab Ductile: Nws cov khoom pub kom yooj yim shaping thiab sib sau, haum rau ntau yam roj teeb tsim.
- Thermal Management: Aluminium pab hauv dissipating tshav kub, tiv thaiv overheating thiab ua kom muaj kev nyab xeeb thiab ua haujlwm ntev.
Hom roj teeb Aluminium ntawv ci
Nov yog qee yam ntawm cov ntawv txhuas txhuas siv hauv cov roj teeb:
- Plain Aluminium Ntawv Nyiaj: High-purity, uncoated ntawv ci rau kev siv hluav taws xob yooj yim thiab kev txhawb nqa txhua yam.
- Coated Aluminium Ntawv Nyiaj: Txhim kho nrog coatings zoo li carbon los yog polymer rau kev txhim kho conductivity, adhesion, thiab tshuaj stability.
- Textured Aluminium Ntawv Nyiaj: Nta ntawm qhov chaw ntxhib los ua kom cov tshuaj tiv thaiv electrochemical, txhim kho lub peev xwm roj teeb.
- Ultra-Thin Aluminium Ntawv Nyiaj: Rau lub teeb yuag thiab hloov tau yooj yim roj teeb, nrog thicknesses tsawg li ob peb micrometers.
- Laminated Aluminium Ntawv Nyiaj: Ntau cov khaubncaws sab nraud povtseg rau kev txhim kho lub zog thiab tiv thaiv kev puas tsuaj rau txhua yam.
