Mphamvu ya Aluminium Foil Processing Technology pa Magwiridwe a Battery

Zotsatira zaukadaulo wa aluminiyumu wopangira ma foil pakugwira ntchito kwa batri ndi nkhani yofunika kwambiri yauinjiniya pamakina osungira mphamvu, monga njira zosinthira mwadongosolo zimasintha mawonekedwe a microstructure, chikhalidwe chapamwamba, ndi zotsalira za kupsinjika maganizo, zomwe zimatsimikizira mwachindunji kukhazikika kwa electrochemical kwanthawi yayitali komanso kudalirika kwamakina kwa otolera a batri cathode.

1. Chiyambi

Mu mabatire osungira mphamvu, zitsulo za aluminiyumu amagwiritsidwa ntchito makamaka ngati osonkhanitsa cathode panopa, ma conduction medium, ndi chithandizo chapang'onopang'ono chapangidwe. Mosiyana ochiritsira structural mankhwala zotayidwa, chojambula cha aluminiyamu cha batri chimagwira ntchito molumikizana mwamphamvu ndi chilengedwe cha electrochemical-thermal-mechanical. Zolephereka kawirikawiri sizichokera ku malire a katundu; m'malo mwake, nthawi zambiri amayendetsedwa ndi zolakwika zazing'ono zomwe zimayambitsidwa panthawi yokonza ndikukulitsidwa pang'onopang'ono panthawi yautumiki. Choncho, kumvetsetsa mwatsatanetsatane za momwe ukadaulo wa aluminiyumu wopangira ma foil pakugwira ntchito kwa batri ndikofunikira pakupanga batire yodalirika yosungira mphamvu..

2. Zida za Aluminium Foil ndi Makhalidwe a Aloyi

Zolemba za aluminiyamu zama batire osungira mphamvu nthawi zambiri zimatengera 1xxx kapena 8xxx ma alloys angapo., omwe katundu wake wamkati amatanthauzira malire a machitidwe akunsi kwa mtsinje.

Kuchokera kumalingaliro aukadaulo, zinthu zinayi ndizofunika kwambiri:

• Kuyankha kwamakina: Aluminiyamu yoyera imawonetsa mphamvu zochepa zokolola; kulimbitsa kumadalira makamaka kachulukidwe wa kusuntha ndi kukonzanso kwambewu komwe kumayambika pakugubuduza.
• Thermal conduction khalidwe: Kutentha kwapamwamba kwa aluminiyumu kumathandizira kutaya kutentha, koma mawonekedwe ogubuduza amapangitsa kuti anisotropy yolunjika.
• Kukana kwa dzimbiri ndi kukhazikika kwa nkhope: M'malo a electrolyte, kupitiriza ndi kukhulupirika kwa filimu ya okusayidi ndizotsimikizika.
• Kupanga: Kugwirizana ndi zokutira, kalendala, kuzepa, ndi njira zowotcherera zimayang'anira kusasinthika kwakukulu kopanga.

Tebulo 1. Mawonekedwe Odziwika a Zolemba Za Aluminium Pamabatire Osungira Mphamvu

Makhalidwe achilengedwe awa amakulitsidwa kwambiri ndi njira zopangira, kupanga maziko a mphamvu ya ukadaulo wa aluminiyumu wopangira ma foil pakuchita kwa batri.

3. Njira Zopangira Aluminiyamu Zopangira Mabatire Osungira Mphamvu

Chojambula cha aluminiyamu cha batri si chinthu chongogudubuzika; ntchito yake imadalira kwambiri njira yokonzekera bwino:

1. Multi-pass cold rolling control
   Kugubuduza kozizira kumatsimikizira kulondola kwa makulidwe omaliza ndi mulingo woyamba woumitsa ntchito, pamene akupanga elongation yambewu ndi mawonekedwe a crystallographic.
2. Mawindo apakati komanso omaliza a annealing
   Annealing kutentha ndi akuwukha nthawi mwachindunji kulamulira recrystallization, kugawa kukula kwambewu, ndi kupumula kupsinjika kotsalira.
3. Kumaliza pamwamba ndi kusamalira ukhondo
   Ming'alu yapamtunda, zotsalira zamafuta, ndipo filimu ya oxide yosafanana imatha kusinthika kukhala malo oyambira kulephera kwa electrochemical.

Kukonzekera mwadongosolo ndikofunikira kuti tisinthe momwe ukadaulo wa aluminiyumu wopangira ma foil pakuchita kwa batri kuchoka ku zosatsimikizika kupita ku zodziwikiratu..

4. Zokhudza Kukonza Magwiridwe A Battery

Pa mlingo wa makina, ukadaulo waukadaulo umakhudza magwiridwe antchito a batri kudzera m'njira zingapo zofunika:

• Interface resistance evolution
  Kukhwimitsa kochititsa chidwi komanso kupsinjika kotsalira kumakhudza kulumikizana pakati pa zigawo zogwira ntchito ndi zojambulazo za aluminiyamu., kukhudza kukula kwa kukana kwamkati.
• Thermo-mechanical kutopa khalidwe
  Pacharge-kutulutsa kutentha kwa njinga, zojambula zosakwanira bwino zimakhudzidwa kwambiri ndi kuchulukana kwa pulasitiki komanso kuyambitsa ming'alu..
• Kusunga umphumphu wamapangidwe
  Kukula kwanjere zosafanana kapena mawonekedwe okhwima amawonjezera mwayi woti makwinya am'deralo kapena makwinya pambuyo popanga ma elekitirodi..

Pamodzi, Zotsatirazi zimatanthawuza ukadaulo wanthawi yayitali waukadaulo wa aluminiyumu wopangira ma foil pakuchita kwa batri.

5. Kufananitsa Kwaukadaulo kwa Makhalidwe Opangira Mapangidwe

Tebulo 2. Zotsatira za Cold Rolling ndi Annealing Strategies pa Aluminium Foil Performance

Tebulo 3. Ubale Pakati pa Zowonongeka Zowonongeka ndi Ma Battery Kulephera Kwamachitidwe

Mafananidwe awa akuwonetsa momveka bwino kuti kusankhidwa kwa magawo kumatsimikizira mwachindunji kuyenerera kwa zojambulazo za aluminiyamu pamabatire osungira mphamvu..

6. Zochitika Zoyenera

Njira zowongolera bwino komanso zoyendetsedwa bwino za aluminiyumu zopangira ma foil ndizoyenera pazotsatira zosungira mphamvu.:

• Moyo wautali wozungulira (≥6000 kuzungulira) zotengera zosungira mphamvu za batire za cathode
• Maselo osungira mphamvu zamalonda ndi mafakitale omwe amafunikira kutentha kwamtundu umodzi
• Mapangidwe a cathode okhala ndi mawonekedwe okhazikika okhazikika

Muzochitika izi, kukhudzidwa kwaukadaulo wopangira ma aluminiyumu pakugwirira ntchito kwa batri kumawonekera ngati kukhazikika kwanthawi yayitali m'malo mochita bwino kwakanthawi kochepa..

7. Zochitika Zosavomerezeka

Zotsatirazi ndizosavomerezeka kumayiko ena opangira zojambulazo za aluminiyamu:

• Zojambula zosakwanira zomwe zimagwiritsidwa ntchito m'makina osungira mphamvu kwa moyo wautali
• Zojambula zosakwanira zaukhondo zomwe zimagwiritsidwa ntchito m'maselo amphamvu kwambiri
• Zojambula zojambulidwa kwambiri zogwiritsidwa ntchito kwambiri, ma modules osungira mphamvu zamakono

Pansi pazimenezi, Zotsatira zaukadaulo wopangira ma aluminiyumu pakuchita kwa batri nthawi zambiri zimawoneka ngati kuwonongeka msanga kapena kutayika kosasinthika..

8. Chidule

Zonse, zotsatira za ukadaulo wa aluminiyumu wopangira ma foil pa magwiridwe antchito a batri ndi a zinthu zogwirizana kwambiri-ntchito-ntchito vuto la chilengedwe. M'mabatire osungira mphamvu-kumene moyo wautali, chitetezo, ndipo kusasinthasintha ndikofunika kwambiri - pokhapokha poyendetsa mwadongosolo kuzizira kozizira, mawindo otsegula, ndi kuyang'anira pamwamba kumatha kukhala ndi zojambula za aluminiyamu kukhalabe zodziwikiratu komanso zotsimikizika zauinjiniya munthawi yonse ya batri.
