Zifukwa zazikulu zamabatire a lithiamu kugwiritsa ntchito zipolopolo za aluminiyamu zitha kufufuzidwa mwatsatanetsatane kuchokera kuzinthu zotsatirazi, zomwe ndizopepuka, kukana kwa dzimbiri, kuwongolera bwino, kugwirira ntchito bwino, kutsika mtengo, ntchito yabwino yotaya kutentha, ndi zina zambiri.
1. Wopepuka
• Kachulukidwe kochepa: Kachulukidwe ka aluminiyamu ndi pafupifupi 2.7 g/cm³, yomwe ndiyotsika kwambiri kuposa yachitsulo, yomwe ndi pafupifupi 7.8 g/cm³. Pazida zamagetsi zomwe zimatsata mphamvu zambiri komanso zopepuka, monga mafoni am'manja, ma laputopu, ndi magalimoto amagetsi, zipolopolo za aluminiyamu zimatha kuchepetsa kulemera konse ndikuwongolera kupirira.
2. Kukana dzimbiri
• Kusinthasintha kwa malo othamanga kwambiri: Mphamvu yogwira ntchito ya lithiamu batri positive electrode zipangizo, monga ternary materials ndi lithiamu cobalt oxide, ndizokwera kwambiri (3.0-4.5V). Kuthekera kumeneku, aluminiyumu ipanga filimu wandiweyani ya aluminium oxide (Al₂O₃) pamwamba kuti isawononge dzimbiri. Chitsulo chimawonongeka mosavuta ndi electrolyte pansi pa kuthamanga kwambiri, zomwe zimapangitsa kuti batire iwonongeke kapena kutayikira.
• Kugwirizana kwa Electrolyte: Aluminiyamu imakhala ndi kukhazikika kwamankhwala kwa organic electrolytes, monga LiPF₆, ndipo sichimakonda kuchitapo kanthu pakugwiritsa ntchito nthawi yayitali.
3. Conductivity ndi kapangidwe kamangidwe
• Kulumikizana kwa osonkhanitsa panopa: Aluminiyamu ndi chinthu chomwe chimakondedwa kwambiri ndi ma electrode amakono otolera (monga zojambulazo za aluminiyamu). Chigoba cha aluminiyamu chimatha kulumikizidwa mwachindunji ndi ma elekitirodi abwino, kufewetsa mawonekedwe amkati, kuchepetsa kukana, ndikuwongolera kufalitsa mphamvu.
• Zofunikira za Shell conductivity: Mu mapangidwe ena a batri, chipolopolo cha aluminiyamu ndi gawo la njira yamakono, monga mabatire a cylindrical, omwe ali ndi ma conductivity ndi chitetezo ntchito.
4. Processing ntchito
• Ductility yabwino kwambiri: Aluminiyamu ndi yosavuta kusindikiza ndi kutambasula, ndipo ndi yoyenera kupanga zazikulu zazikulu za mawonekedwe ovuta, monga mafilimu a aluminium-pulasitiki kwa mabatire a square ndi soft-pack. Zipolopolo zachitsulo zimakhala zovuta kukonza komanso zimakhala zokwera mtengo.
• Chitsimikizo chosindikizira: Ukadaulo wowotcherera zipolopolo za Aluminium ndi wokhwima, monga kuwotcherera kwa laser, komwe kumatha kusindikiza bwino electrolyte, kuteteza chinyezi ndi mpweya kuti zisalowe, ndikuwonjezera moyo wa batri.
5. Kuwongolera kutentha
• Kutentha kwakukulu kwa kutentha: Kutentha kwazitsulo za aluminiyamu (pafupifupi 237 W / m·K) ndipamwamba kwambiri kuposa zitsulo (pafupifupi 50 W / m · K), zomwe zimathandiza kuti batire iwononge kutentha mwamsanga pamene ikugwira ntchito ndi kuchepetsa chiopsezo cha kutentha kwa kutentha.
6. Mtengo ndi chuma
• Mtengo wotsika wazinthu ndi kukonza: Mtengo wa aluminiyumu wamtengo wapatali ndi wochepa, ndipo mphamvu yogwiritsira ntchito mphamvu ndi yochepa, yomwe ili yoyenera kupanga zazikulu. Mosiyana ndi zimenezi, zipangizo monga zitsulo zosapanga dzimbiri ndizokwera mtengo kwambiri.
7. Kukonzekera kwachitetezo
• Makina oletsa kupanikizika: Zipolopolo za aluminiyamu zimatha kutulutsa mphamvu yamkati ndikupewa kuphulika ngati kuchucha kapena kuthawa chifukwa cha kutentha popanga ma valve oteteza chitetezo, monga mawonekedwe a CID a mabatire a cylindrical.
8. Zochita zamakampani ndi kukhazikika
• Zipolopolo za aluminiyamu zakhala zikugwiritsidwa ntchito kwambiri kuyambira masiku oyambirira a malonda a lithiamu batire, monga batire ya 18650 yomwe inayambitsidwa ndi Sony mu 1991, kupanga makina okhwima a mafakitale ndi miyezo yaumisiri, kulimbikitsanso malo ake akuluakulu.
Nthawi zonse pali zosiyana. Muzochitika zina zapadera, zipolopolo zachitsulo zimagwiritsidwanso ntchito:
Nthawi zina zokhala ndi mphamvu zamakina okwera kwambiri, monga mabatire amagetsi kapena kugwiritsa ntchito kwambiri chilengedwe, zipolopolo zachitsulo za nickel zitha kugwiritsidwa ntchito, koma mtengo wake ndi wolemera komanso mtengo wake.
Mapeto
Zipolopolo za aluminiyamu zakhala chisankho chabwino cha zipolopolo za batri la lithiamu chifukwa cha ubwino wawo wonse monga kulemera kwa kuwala, kukana kwa dzimbiri, kutsekemera kwabwino, kukonza kosavuta, kutentha kwabwino kwambiri komanso kutsika mtengo, kugwirizanitsa bwino ntchito, chitetezo ndi zofunikira zachuma.
