Kupanga kwamabatire a lithiamundi ndondomeko ya "roll-to-roll".Kaya ndi batire ya lithiamu iron phosphorous, batire ya sodium-ion kapena batire ya ternary, iyenera kudutsa njira yosinthira kuchokera ku filimu yopyapyala kupita ku batri imodzi, kenako kupita ku batire.Kukonzekera kwa mabatire a lithiamu kumatha kugawidwa m'magawo atatu: kupanga pepala la electrode, kaphatikizidwe ka cell, ndi kuyika mankhwala.
Pali njira zingapo zazikuluzikuluzikuluzikuluzikuluzikulu zitatuzi, zomwe zidzakhudze mphamvu yosungira mphamvu ya batri, chitetezo cha mankhwala ndi moyo wautumiki.Chifukwa chake, magwiridwe antchito a mabatire opangidwa ndi njira zosiyanasiyana zopangira amasiyana kwambiri.Mu maulalo awa,laser kuyeretsatsopano akhoza kutenga nawo mbali mu njira zoposa khumi ndi ziwiri zokonzekera, zomwe zingathe kusintha kwambiri mlingo wa mabatire a lithiamu.

Pamene kufunikira kwa mabatire amphamvu kukukulirakulira, kufunikira kwalaser kuyeretsazida zidzawonjezekanso.Kenaka, tidzayang'ana njira zina zogwiritsira ntchito komanso ubwino wofananitsa.
1. Kuyeretsa ndi laser kwa zojambulazo zamkuwa ndi aluminiyamu musanaphike chidutswa chamtengo
Ma elekitirodi abwino ndi oipa a batire ya lithiamu amapangidwa poyala ma elekitirodi abwino ndi oipa a batire ya lithiamu pa chojambula cha aluminiyamu ndi zojambulazo zamkuwa.Ngati tinthu tating'onoting'ono, zinyalala, fumbi ndi zofalitsa zina zimasakanizidwa mu zokutira, zingayambitse gawo laling'ono laling'ono mkati mwa batri, ndipo pakavuta kwambiri, batire imagwira moto ndikuphulika.
Chifukwa chake, zojambulazo zimafunika kutsukidwa musanaphike kuti zipeze malo oyera, opanda oxide.
Zomwe zilipo batire mzati zidutswa zambiri kutsukidwa ndi akupanga mafunde, ndi Mowa njira ntchito ngati kuyeretsa wothandizila monga kuyeretsa ndondomeko pamaso ❖ kuyanika.Njira iyi ili ndi zolakwika izi:
1. Pamene ultrasonically kuyeretsa zitsulo zojambulazo mbali, makamaka zotayidwa aloyi workpieces, anakhudzidwa ndi pafupipafupi, kuyeretsa nthawi ndi mphamvu, ndi cavitation zotsatira za akupanga mafunde mosavuta dzimbiri zotayidwa zojambulazo, chifukwa chabwino pores.Kutalikirapo nthawi yochitapo kanthu, pores amakula.
Chojambulacho chomwe chimagwiritsidwa ntchito pa chidutswa cha batire ya lithiamu nthawi zambiri chimakhala chojambula cha zero chimodzi chokhala ndi makulidwe a 10 μm, chomwe chimakonda kung'ambika m'mabowo chifukwa cha zovuta zoyeretsa.
2. Kugwiritsa ntchito njira ya ethanol monga choyeretsa sikophweka kokha kuwononga mbali zina za batri ya lithiamu, komanso kumakonda "hydrogen embrittlement", zomwe zimakhudza makina a aluminium zojambulazo.
3. Ngakhale kuyeretsa kumakhala koyipa kwambiri kuposa kuyeretsa kwamankhwala konyowa, ukhondo sunali wabwino ngati woyeretsa laser.Nthawi zina pamakhala zonyansa pamwamba, zomwe zimapangitsa kuti zokutira zisiyanitse ndi zojambulazo kapena kutulutsa mabowo ocheperako.
Monga kuyeretsa kouma kopanda zogwiritsira ntchito, kuyeretsa kwa laser kuli pafupi ndi ziro zolakwika paukhondo ndi hydrophilicity ya mankhwala opangidwa ndi aluminiyamu, kuwonetsetsa kuti makulidwe ndi zokutira pachidutswa chachikulu kwambiri.
Kugwiritsa ntchito laser kuyeretsa zitsulo zojambulazo sikungangopangitsa kuti ntchito yoyeretsera ikhale yabwino komanso kupulumutsa zinthu zoyeretsera, komanso kukhazikitsa kuwunika kwenikweni kwa data yoyeretsa ndikutsimikiza kuchulukira kwa zotsatira zoyeretsa, zomwe zitha kusintha bwino kusasinthika kwa kupanga kwa batch. zidutswa za mtengo.
2. Laser kuyeretsa batire tabu pamaso kuwotcherera
Ma tabuwa ndi zingwe zachitsulo zomwe zimatulutsa ma elekitirodi abwino ndi oyipa kuchokera mu cell ya batri, ndipo ndi malo olumikizirana batire ikachajitsidwa ndikutulutsidwa.Zowonongeka zapamtunda monga mafuta, corrosion inhibitors ndi zinthu zina zomwe zimapangidwira zimatha kuyambitsa mavuto monga ma welds osauka, ming'alu ndi porosity mu weld.
Ukhondo wa kukhudzana pamwamba angakhudze kwambiri kudalirika ndi durability kugwirizana magetsi.
Kuyeretsa komwe kulipo nthawi zambiri kumatengera kuyeretsa pamanja, kuyeretsa mankhwala onyowa kapena kuyeretsa plasma:
● Kuyeretsa pamanja n’kosathandiza komanso kumawononga ndalama zambiri;
● Ngakhale njira yonyowa kuyeretsa madzi kumapangitsa kuti ntchito ikhale yabwino, kutalika kwa mzerewu ndi wautali, imakhala ndi gawo lalikulu la fakitale, ndipo wothandizira mankhwala ndi osavuta kuwononga mbali zina za batri ya lithiamu;
● Ngakhale kuti kuyeretsa kwa plasma sikufuna sing'anga yamadzimadzi, kumafunikanso gasi wamagetsi ngati chinthu chogwiritsidwa ntchito, ndipo ionization ya gasi idzachititsa kuti ma electrode abwino ndi oipa a batri atsegulidwe mosavuta.Mukamagwiritsa ntchito, nthawi zambiri ndikofunikira kutembenuza batire kangapo kuti mulekanitse ma elekitirodi abwino ndi oyipa kuti muyeretse.The Mwachangu kwenikweni Osati mkulu.
Kuyeretsa kwa laser kumatha kuchotsa dothi, fumbi, etc. pa mapeto a nkhope ya batire mzati, ndi kukonzekera batire kuwotcherera pasadakhale.
Chifukwa kuyeretsa kwa laser sikufuna zinthu zina monga zolimba, zamadzimadzi ndi gasi, kapangidwe kake kamakhala kakang'ono, malo omwe amakhalapo ndi ochepa, ndipo kuyeretsa kwake ndi kodabwitsa, komwe kumatha kusintha kwambiri kayendedwe kazinthu ndikuchepetsa mtengo wopanga;
Iwo akhoza roughen ndi kuwotcherera pamwamba pa maziko a bwinobwino kuchotsa zinthu organic ndi ting'onoting'ono particles, ndi kusintha kudalirika wotsatira laser kuwotcherera.Ndi imodzi mwazosankha zabwino kwambiri zotsuka ma tabo.
3. Kuyeretsa zomatira zakunja panthawi ya msonkhano
Pofuna kupewa ngozi zachitetezo zamabatire a lithiamu, nthawi zambiri ndikofunikira kugwiritsa ntchito guluu ku maselo a batri a lithiamu kuti agwire ntchito yotchinga, kuteteza mabwalo amfupi, kuteteza mabwalo, komanso kupewa kukwapula.
Pamene filimu yakunja ya selo lodetsedwa imayesedwa ndi CCD, padzakhala makwinya, mavuvu a mpweya, zokopa ndi zofooka zina mu maonekedwe, ndi mavuvu a mpweya okhala ndi ≥ 0.3mm nthawi zambiri amatha kudziwika.Pali kuthekera kwa kutayikira ndi dzimbiri, zomwe zimachepetsa moyo wa batri komanso zimakhala ndi zoopsa zachitetezo.
Kuyeretsa kwa laserimatha kufika mulingo wa Sa3 pakuyeretsa kwa cell, ndipo kuchuluka kwa kuchotsa kumaposa 99,9%;ndipo palibe kupsinjika pamwamba pa selo.Poyerekeza ndi njira zina zoyeretsera monga ultrasonic kuyeretsa kapena makina akupera, zikhoza kuonetsetsa kuti thupi ndi mankhwala zizindikiro monga pamwamba kuuma kwa batire maselo sasintha kwambiri. , ndikutalikitsa moyo wautumiki wa batri.
Kuphatikiza pazitsanzo zomwe tatchulazi, kuyeretsa kwa laser kulinso ndi maubwino ena munjira zina khumi ndi ziwiri monga kuchotsa utoto wa batri wa electrophoretic ndi kuyeretsa zilembo zamakalata.
Ngati mukufuna kudziwa zambiri za kuyeretsa laser, kapena mukufuna kukugulirani makina abwino kwambiri oyeretsera laser, chonde siyani uthenga patsamba lathu ndikutumiza imelo mwachindunji!
