Battery shell aluminiyamu zojambulazo imagwira ntchito yofunika kwambiri paukadaulo wamakono wa batri, makamaka mu mabatire a lithiamu-ion, mabatire a nickel-metal hydride, ndi machitidwe ena apamwamba osungira mphamvu.
Komwe Mungagwiritsire Ntchito Chojambula cha Aluminiyamu Pamilandu Ya Battery
Aluminium zojambulazo is employed in the construction of battery cases for:
- Mabatire a lithiamu-ion: Kwa iwo opepuka, kuchuluka kwamphamvu kwamphamvu, ndi kusinthasintha.
- Mabatire a Nickel-Metal Hydride: Kupereka njira ina yolimba pamapulogalamu omwe amafunikira kuchuluka kwa zotulutsa.
- Mitundu ina ya Battery: Kuphatikizira mabatire a thumba ndi mabatire a square mabatire.
Chojambulacho chimakhala ngati chotchinga choteteza mkati mwa batire, kuteteza kulowetsedwa kwa chinyezi ndi mpweya, zomwe zitha kusokoneza magwiridwe antchito a batri pakapita nthawi.
Chifukwa Chake Mugwiritsire Ntchito Chojambula cha Aluminiyamu Pamilandu Ya Battery?
- Kukaniza kwa Corrosion: Aluminiyamu mwachilengedwe amapanga wosanjikiza wa oxide, kupereka bwino kukana dzimbiri, zomwe ndizofunikira kwambiri kuti musunge kukhulupirika kwa batri.
- Conductivity: Aluminium yapamwamba yamagetsi yamagetsi imapangitsa kuyenda bwino kwapano, kukulitsa magwiridwe antchito a batri.
- Opepuka ndi Ductile: Makhalidwe ake amalola kupanga mosavuta ndi kupanga, kutengera mapangidwe osiyanasiyana a batri.
- Thermal Management: Aluminium imathandizira kutulutsa kutentha, kuteteza kutenthedwa ndi kuonetsetsa chitetezo ndi moyo wautali.
Mitundu ya Battery Aluminium Foil
Nayi mitundu yodziwika bwino ya zojambula za aluminiyamu zomwe zimagwiritsidwa ntchito m'mabatire:
- Chojambula Chopanda Aluminiyamu: Kuyera kwambiri, zojambulazo zosavala zopangira ma conductivity oyambira komanso chithandizo chamakina.
- Zovala za Aluminium Zokutidwa: Kuwonjezeredwa ndi zokutira ngati kaboni kapena polima kuti muzitha kuyendetsa bwino, kumamatira, ndi kukhazikika kwa mankhwala.
- Chojambula cha Aluminium Chopangidwa: Ili ndi mawonekedwe opangidwa kuti awonjezere malo a electrochemical reaction, kupititsa patsogolo mphamvu ya batri.
- Ultra-Thin Aluminium Chojambula: Kwa mabatire opepuka komanso osinthika, ndi makulidwe otsika ngati ma micrometer ochepa.
- Chojambula cha Aluminium chopangidwa ndi laminated: Zigawo zingapo zomangika kuti ziwonjezere mphamvu komanso kukana kuwonongeka kwamakina.

Ubwino wa Battery Aluminium Foil
- Zapamwamba Zakuthupi: High conductivity ndi kukana dzimbiri kumawonjezera moyo wa batri.
- Yofewa komanso Yosavuta Kukonza: Imathandizira kupanga ma electrode, kuchepetsa ndalama.
- Kuteteza Osonkhanitsa Pano: Imakulitsa kukhazikika kwa batri popewa kuwonongeka kwa makina ndi mankhwala.
Katundu Wamakina ndi Kukaniza Magetsi
- Kulimba kwamakokedwe: Zimasiyanasiyana ndi aloyi ndi mkwiyo, makamaka kuyambira 150 ku 200 N/mm².
- Elongation: Imatsimikizira kusinthasintha komanso kukana kusweka.
- Kukaniza Magetsi: Amachepetsa ndi kuchuluka kwa makulidwe, kuchokera 0.55 Ω.m pa 0.0060 mm kuti 0.25 Ω.m pa 0.16 mm.

Zofunikira Zamtundu wa Battery-Grade Aluminium Foil
- Surface Uniformity, Ukhondo, ndi Smoothness: Imawonetsetsa magwiridwe antchito abwino komanso moyo wautali.
- Palibe Zowonongeka Zozungulira: Imaletsa zovuta ngati ma creases ndi madontho omwe angakhudze moyo wa batri.
- Mtundu Wogwirizana: Imaletsa kusiyanasiyana komwe kungakhudze kusasinthika kwa batri.
- Palibe Kuipitsidwa kwa Mafuta kapena Madontho: Amasunga ukhondo kuti agwire bwino ntchito.
Njira Yopangira Battery Aluminium Foil
- Kuponya: Aluminium imasungunuka ndikuponyedwa muzitsulo kapena matabwa.
- Hot Rolling: Amachepetsa makulidwe pa kutentha kwakukulu.
- Cold Rolling: Komanso amachepetsa makulidwe firiji.
- Annealing: Kumawonjezera kusinthasintha ndi mphamvu.
- Kumaliza: Kuchepetsa, mankhwala pamwamba, ndi kulamulira khalidwe.
- Slitting ndi Packaging: Kukonzekera zojambulazo kuti zigawidwe.
Mafunso Ofunsidwa Kawirikawiri Okhudza Chojambula cha Aluminiyamu cha Battery Case
- Kodi chojambula chilichonse cha aluminiyamu chingagwiritsidwe ntchito pamilandu ya batri? Ayi, ma aloyi enieni ndi mafotokozedwe amafunikira kuti agwire bwino ntchito.
- Kodi zojambulazo za aluminiyamu zimathandizira bwanji chitetezo cha batri? Popereka kukana dzimbiri, kuthandizira pakuwongolera kutentha, ndi kuonetsetsa kuti conductivity ikugwirizana.
- Ndiyenera kuchita chiyani ndikawona dzimbiri pachojambula cha aluminiyamu? Fufuzani chomwe chimayambitsa ndipo ganizirani kugwiritsa ntchito ma alloys osamva kapena zokutira zoteteza.
