Kuyeretsa kwa Laser kwa Kupanga Mabatire Amagetsi

Kupanga kwamabatire a lithiamundi njira ya "roll-to-roll". Kaya ndi batire ya lithiamu iron phosphate, batire ya sodium-ion kapena batire ya ternary, iyenera kudutsa mu njira yokonza kuyambira filimu yopyapyala kupita ku batire imodzi, kenako kupita ku dongosolo la batire. Njira yokonzekera mabatire a lithiamu ikhoza kugawidwa m'magawo atatu: kupanga pepala la electrode, kupanga maselo, ndi kuyika mankhwala.

Pali njira zingapo zofunika kwambiri mu njira zitatu zazikuluzi, zomwe zimakhudza mwachindunji mphamvu yosungira mphamvu ya batri, chitetezo cha chinthucho, ndi moyo wautumiki. Chifukwa chake, magwiridwe antchito a mabatire opangidwa ndi njira zosiyanasiyana zopangira amasiyana kwambiri. Mu maulalo awa,kuyeretsa ndi laserpakadali pano akhoza kutenga nawo mbali m'njira zokonzekera zoposa khumi ndi ziwiri, zomwe zingathandize kwambiri kuchuluka kwa mabatire a lithiamu.

Pamene kufunikira kwa mabatire amagetsi kukupitirira kukwera, kufunikira kwakuyeretsa ndi laserZipangizo nazonso zidzawonjezeka. Kenako, tidzayang'ana kwambiri njira zina zogwiritsira ntchito ndi ubwino woyerekeza.

1. Kuyeretsa kwa laser kwa mkuwa ndi aluminiyamu musanaphimbe pole piece piece

Ma electrode abwino ndi oipa a batire ya lithiamu amapangidwa popaka ma electrode abwino ndi oipa a batire ya lithiamu pa foil ya aluminiyamu ndi foil yamkuwa. Ngati tinthu tating'onoting'ono, zinyalala, fumbi ndi zinthu zina zolumikizirana zisakanizidwa panthawi yopaka, zingayambitse circuit yaying'ono mkati mwa batire, ndipo pazochitika zoopsa, batireyo idzayaka moto ndikuphulika.

Chifukwa chake, zojambulazo ziyenera kutsukidwa musanazipake kuti pakhale malo oyera komanso opanda oxide.

Zidutswa za batire zomwe zilipo nthawi zambiri zimatsukidwa ndi mafunde a ultrasound, ndipo yankho la ethanol limagwiritsidwa ntchito ngati chotsukira ngati njira yotsukira musanaphike. Njira iyi ili ndi zolakwika izi:

1. Mukatsuka ziwalo zachitsulo pogwiritsa ntchito ultrasound, makamaka zinthu zogwirira ntchito za aluminiyamu, zomwe zimakhudzidwa ndi kuchuluka kwa nthawi, nthawi yoyeretsera ndi mphamvu, mphamvu ya mafunde a ultrasound imatha kuwononga mosavuta zojambulazo za aluminiyamu, zomwe zimapangitsa kuti pakhale ma pores abwino. Nthawi yayitali yogwira ntchito, ma pores amakula.

Foyilo yomwe imagwiritsidwa ntchito pa chidutswa cha batire ya lithiamu nthawi zambiri imakhala foyilo imodzi yopanda kanthu yokhala ndi makulidwe a 10 μm, yomwe imakonda kung'ambika m'mabowo chifukwa cha mavuto oyeretsa.

2. Kugwiritsa ntchito njira ya ethanol ngati chotsukira sikungowononga mbali zina za batire ya lithiamu, komanso kumayambitsa "kuphulika kwa haidrojeni", zomwe zimakhudza mphamvu zamakina a pepala la aluminiyamu.

3. Ngakhale kuti kuyeretsa kumakhala koipa kuposa kuyeretsa kwachikhalidwe pogwiritsa ntchito mankhwala onyowa, ukhondo wake suli wabwino ngati kuyeretsa pogwiritsa ntchito laser. Nthawi zina pamakhala zinthu zodetsa pamwamba, zomwe zimapangitsa kuti utotowo usiyane ndi zojambulazo kapena kupanga mabowo ocheperako.

Monga njira yoyeretsera youma popanda zinthu zogwiritsidwa ntchito, kuyeretsa kwa laser kuli pafupifupi kopanda zolakwika pankhani ya ukhondo ndi kusinthasintha kwa madzi pakhungu la zojambulazo za aluminiyamu, zomwe zimawonetsetsa kuti kukula ndi utoto wa chinthucho zikugwira ntchito bwino kwambiri.

Kugwiritsa ntchito pepala lachitsulo loyeretsera pogwiritsa ntchito laser sikungowonjezera mphamvu ya njira yoyeretsera ndikusunga zinthu zoyeretsera, komanso kukhazikitsa kuwunika nthawi yeniyeni deta ya njira yoyeretsera ndi kutsimikiza kuchuluka kwa zotsatira zoyeretsera, zomwe zingathandize bwino kupanga zidutswa za ndodo.

2. Kuyeretsa mabatire pogwiritsa ntchito laser musanawotchetse

Ma tabu ndi timizere tachitsulo tomwe timatulutsa ma electrode abwino ndi oipa kuchokera mu selo ya batri, ndipo ndi malo olumikizirana batri ikachajidwa ndikutulutsidwa. Zoipitsa pamwamba monga mafuta, zoletsa dzimbiri ndi zinthu zina zomwe zimachitika panthawiyi zingayambitse mavuto monga ma weld osalimba, ming'alu ndi ma porosity mu weld.

Ukhondo wa pamwamba pa malo olumikizirana ungakhudze kwambiri kudalirika ndi kulimba kwa kulumikizana kwa magetsi.

Kuyeretsa kwa ma electrode komwe kulipo nthawi zambiri kumagwiritsa ntchito kuyeretsa kwamanja, kuyeretsa mankhwala onyowa kapena kuyeretsa kwa plasma:

● Kuyeretsa ndi manja sikugwira ntchito bwino komanso kumawononga ndalama zambiri;

● Ngakhale kuti mzere woyeretsera madzi wonyowa umathandiza kuti ntchito iyende bwino, kutalika kwa mzerewo ndi wautali, umakhala m'dera lalikulu la fakitale, ndipo mankhwala ophera tizilombo amathanso kuwononga ziwalo zina za batri ya lithiamu mosavuta;

● Ngakhale kuyeretsa plasma sikufuna madzi, kumafunanso mpweya wokonzedwa ngati chinthu chogwiritsidwa ntchito, ndipo ionization ya mpweya idzapangitsa kuti ma electrode abwino ndi oipa a batri azitsegulidwa mosavuta. Mukamagwiritsa ntchito, nthawi zambiri ndikofunikira kutembenuza batri kangapo kuti mulekanitse ma electrode abwino ndi oipa kuti muyeretse. Kugwiritsa ntchito bwino kwenikweni Sikuli kokwera.

Kuyeretsa kwa laser kumatha kuchotsa bwino dothi, fumbi, ndi zina zotero kumapeto kwa ndodo ya batri, ndipo konzekerani kuwotcherera batri pasadakhale.

Popeza kuyeretsa pogwiritsa ntchito laser sikufuna zinthu zina monga zolimba, zamadzimadzi ndi gasi, kapangidwe kake ndi kakang'ono, malo omwe ali ndi malo ochepa, ndipo kuyeretsa kwake ndi kodabwitsa, zomwe zingathandize kwambiri kupanga ndikuchepetsa mtengo wopanga;

Imatha kuwononga pamwamba pa cholumikizira pogwiritsa ntchito kuchotsa bwino zinthu zachilengedwe ndi tinthu ting'onoting'ono, ndikuwonjezera kudalirika kwa cholumikizira cha laser chotsatira. Ndi imodzi mwazisankho zabwino kwambiri pakuyeretsa ma tabu.

3. Kuyeretsa guluu wakunja panthawi yopangira

Pofuna kupewa ngozi zachitetezo cha mabatire a lithiamu, nthawi zambiri ndikofunikira kugwiritsa ntchito guluu m'maselo a batire a lithiamu kuti agwire ntchito yoteteza kutentha, kupewa ma circuit afupiafupi, kuteteza ma circuit, komanso kupewa kukwawa.

Pamene filimu yakunja ya selo losadetsedwa iyesedwa ndi CCD, padzakhala makwinya, thovu la mpweya, mikwingwirima ndi zolakwika zina m'mawonekedwe, ndipo thovu la mpweya lokhala ndi mainchesi a ≥ 0.3mm nthawi zambiri limatha kupezeka. Pali kuthekera kwa kutayikira ndi dzimbiri, zomwe zimachepetsa moyo wa batri komanso zingakhale ndi zoopsa zotetezera.

Kuyeretsa ndi laserimatha kufika pamlingo wa Sa3 pakutha kuyeretsa pamwamba pa selo, ndipo kuchuluka kwa kuchotsedwa kwake ndi kopitilira 99.9%; ndipo palibe kupsinjika pamwamba pa selo. Poyerekeza ndi njira zina zoyeretsera monga kuyeretsa kwa ultrasound kapena kupukuta kwamakina, imatha kuwonetsetsa kuti zizindikiro zakuthupi ndi zamakemikolo monga kuuma kwa pamwamba pa maselo a batri sizisintha kwambiri, ndikuwonjezera moyo wa batri.

Kuwonjezera pa zitsanzo zomwe zatchulidwa pamwambapa, kuyeretsa pogwiritsa ntchito laser kulinso ndi ubwino wina wabwino m'njira zina zambiri monga kuchotsa utoto pogwiritsa ntchito electrophoretic cover komanso kuyeretsa zilembo za foil.

Ngati mukufuna kudziwa zambiri zokhudza kuyeretsa pogwiritsa ntchito laser, kapena mukufuna kugula makina abwino kwambiri oyeretsera pogwiritsa ntchito laser, chonde titumizireni uthenga patsamba lathu ndipo titumizireni imelo mwachindunji!
