Ho Hloekisa Laser bakeng sa Tlhahiso ea Battery ea Matla

Tlhahiso ealibeteri tsa lithiumke ts'ebetso ea "roll-to-roll".Hore na ke betri ea lithium iron phosphate, betri ea sodium-ion kapa betri ea ternary, e hloka ho feta ts'ebetsong ho tloha filiming e tšesaane ho ea ho betri e le 'ngoe, ebe ho ea ho sistimi ea betri.Ts'ebetso ea ho lokisa libeteri tsa lithium e ka aroloa ka mekhahlelo e meraro: tlhahiso ea letlapa la li-electrode, synthesis ea lisele, le ho paka lik'hemik'hale.

Ho na le lits'ebetso tse 'maloa tsa bohlokoa lits'ebetsong tsena tse tharo tse kholo, tse tla ama ka kotloloho matla a polokelo ea matla a betri, polokeho ea sehlahisoa le bophelo ba ts'ebeletso.Ka hona, ts'ebetso ea libeteri tse hlahisoang ke mekhoa e fapaneng ea tlhahiso e fapana haholo.Lihokelong tsena,ho hloekisa laserhajoale e ka kenya letsoho lits'ebetsong tse fetang leshome le metso e 'meli tsa ho lokisa, tse ka ntlafatsang haholo sekhahla sa boleng ba libeteri tsa lithium.

Ha tlhokahalo ea libeteri tsa motlakase e ntse e eketseha, tlhokahalo eaho hloekisa laserlisebelisoa le tsona li tla eketseha.Ka mor'a moo, re tla tsepamisa maikutlo ho tse ling tsa mekhoa ea kopo le melemo ea ho bapisa.

1. Ho hloekisoa ka laser ea foil ea koporo le aluminium pele ho roala karoloana ea palo

Li-electrode tse ntle le tse mpe tsa betri ea lithium li entsoe ka ho roala li-electrode tse ntle le tse mpe tsa betri ea lithium holim'a foil ea aluminium le foil ea koporo.Haeba likaroloana, lithōle, lerōle le mecha e meng ea litaba li kopantsoe ka mokhoa oa ho roala, ho tla etsa hore potoloho e khutšoanyane e nyenyane ka hare ho betri, 'me maemong a boima, betere e tla tšoara mollo ebe e phatloha.

Ka hona, foil e hloka ho hloekisoa pele e roaloa ho fumana sebaka se hloekileng ka ho feletseng, se se nang oxide.

Likarolo tse teng tsa libeteri ka kakaretso li hloekisoa ke maqhubu a ultrasonic, 'me tharollo ea ethanol e sebelisoa e le mokhoa oa ho hloekisa e le mokhoa oa ho hloekisa pele o roala.Mokhoa ona o na le mefokolo e latelang:

1. Ha ultrasonically hloekisa likarolo tsa tšepe ea tšepe, haholo-holo aluminium alloy workpieces, e anngoeng ke makhetlo a mangata, nako ea ho hloekisa le matla, phello ea cavitation ea maqhubu a ultrasonic e ka senya habonolo foil ea aluminium, e fellang ka li-pores tse ntle.Ha nako e ntse e feta, li-pores li kholoanyane.

Foil e sebelisoang bakeng sa sekhechana sa palo ea betri ea lithium hangata ke foil e le 'ngoe ea zero e nang le botenya ba 10 μm, e atisang ho phunya masoba ka lebaka la mathata a ho hloekisa.

2. Tšebeliso ea tharollo ea ethanol e le moemeli oa ho hloekisa ha ho bonolo feela ho baka tšenyo likarolong tse ling tsa betri ea lithium, empa hape e tloaelehile ho "hydrogen embrittlement", e amang thepa ea mechine ea foil ea aluminium.

3. Le hoja phello ea ho hloekisa e le mpe ho feta ea tloaelo ea ho hloekisa lik'hemik'hale tse metsi, bohloeki bo ntse bo se botle joaloka ho hloekisa ka laser.Ka linako tse ling ho ntse ho e-na le litšila holim'a metsi, e leng se tla etsa hore seaparo se arohane le foil kapa se hlahise masoba a shrinkage.

Joalo ka tlhoekiso e ommeng ntle le lisebelisoa, ho hloekisa ka laser ho haufi le mefokolo ea zero ho latela bohloeki le hydrophilicity ea kalafo ea bokaholimo ba foil ea aluminium, ho netefatsa phello ea boholo le ho roala holim'a sekotoana sa palo ho isa tekanyong e kholo.

Tšebeliso ea "laser" ea tšepe e hloekisang e ke ke ea ntlafatsa feela ts'ebetso ea ts'ebetso ea ho hloekisa le ho boloka lisebelisoa tsa ho hloekisa, empa hape e ka theha tlhahlobo ea nako ea 'nete ea data ea ts'ebetso ea ho hloekisa le boikemisetso ba palo ea liphetho tsa ho hloekisa, tse ka ntlafatsang ka nepo botsitso ba tlhahiso ea batch. likotoana tsa palo.

2. Ho hloekisa ka laser li-tab tsa betri pele ho tjheseletsa

Li-tab ke likhoele tsa tšepe tse etellang pele li-electrode tse ntle le tse mpe ho tsoa seleng ea betri, 'me ke libaka tsa ho ikopanya ha betri e tjhajoa le ho tsoa.Lintho tse silafatsang ka holim'a metsi tse kang grease, corrosion inhibitors le metsoako e meng ts'ebetsong li ka baka mathata a kang li-welds tse futsanehileng, mapetsong le porosity ho weld.

Ho hloeka ha sebaka sa ho kopana ho ka ama haholo ho tšepahala le ho tšoarella ha khokahanyo ea motlakase.

Tlhoekiso ea elektrode e teng hangata e sebelisa ho hloekisa ka letsoho, ho hloekisa lik'hemik'hale tse metsi kapa ho hloekisa plasma:

● Ho hloekisa ka letsoho ha ho sebetse hantle ebile ho bitsa chelete e ngata;

● Le hoja mohala oa ho hloekisa metsi oa mokhoa oa metsi o ntlafatsa katleho, bolelele ba mohala o telele, o nka sebaka se seholo sa fektheri, 'me moemeli oa lik'hemik'hale o boetse o bonolo ho senya likarolo tse ling tsa lithium betri;

● Le hoja ho hloekisa plasma ho sa hloke mokhoa oa metsi, ho boetse ho hloka khase ea ts'ebetso e le ntho e ka sebelisoang, 'me ionization ea khase e tla etsa hore li-electrode tse ntle le tse mpe tsa betri li bulehe habonolo.Ha o kenya kopo, hangata hoa hlokahala ho phethola betri ka makhetlo a 'maloa ho arola li-electrode tse ntle le tse mpe bakeng sa ho hloekisa.Bokhoni ba sebele Ha bo phahame.

Ho hloekisa ka laser ho ka tlosa litšila, lerōle ka katleho, joalo-joalo sefahlehong sa qetellong sa palo ea betri, 'me u itokisetse tjheseletsa ea betri esale pele.

Hobane ho hloekisa ka laser ha ho hloke lisebelisoa tse kang tse tiileng, metsi le khase, sebopeho se kopane, sebaka se nkiloeng se nyane, 'me phello ea ho hloekisa e tsoteha, e ka ntlafatsang haholo potoloho ea tlhahiso le ho fokotsa litšenyehelo tsa tlhahiso;

E ka etsa hore bokaholimo ba welding bo be thata ka lebaka la ho tlosa lintho tse phelang hantle le likaroloana tse nyane, 'me ea ntlafatsa ts'epahalo ea ts'ebetso ea laser e latelang.Ke e 'ngoe ea likhetho tse ntle ka ho fetisisa tsa ho hloekisa li-tab.

3. Ho hloekisa sekhomaretsi sa ka ntle nakong ea kopano

E le ho thibela likotsi tsa polokeho ea libeteri tsa lithium, hangata hoa hlokahala ho sebelisa sekhomaretsi liseleng tsa betri tsa lithium ho bapala karolo e sireletsang, ho thibela lipotoloho tse khutšoane, ho sireletsa lipotoloho le ho thibela mengoallo.

Ha filimi e ka ntle ea sele e sa hloekang e lekoa ke CCD, ho tla ba le wrinkles, li-bubble tsa moea, li-scratches le liphoso tse ling ka ponahalo, 'me li-bubble tsa moea tse nang le bophara ba ≥ 0.3mm hangata li ka fumanoa.Ho na le monyetla oa ho lutla le ho rusa, e leng ho fokotsang bophelo ba betri hape ho na le likotsi tse ka bang teng tsa polokeho.

Ho hloekisa ka lasere ka fihla boemong ba Sa3 ka bokhoni ba ho hloekisa sebaka sa sele, 'me sekhahla sa ho tlosoa se feta 99,9%;'me ha ho na khatello ea kelello holim'a sele.Ha ho bapisoa le mekhoa e meng ea ho hloekisa e kang ho hloekisa ka ultrasonic kapa ho sila ka mechine, e ka etsa bonnete ba hore lipontšo tsa' mele le lik'hemik'hale tse kang boima ba holim'a lisele tsa betri ha li fetohe ka tekanyo e kholo ka ho fetisisa. , le ho lelefatsa bophelo ba tšebeletso ea betri.

Ntle le mehlala e boletsoeng ka holimo, ho hloekisa ka laser ho boetse ho na le melemo e meng e mengata lits'ebetsong tse ling tse kang ho tlosa pente ea electrophoretic le ho hloekisa li-label tsa foil.

Haeba u batla ho ithuta ho eketsehileng ka ho hloekisa ka laser, kapa u batla ho u rekela mochine o molemo ka ho fetisisa oa ho hloekisa ka laser, ka kopo siea molaetsa ho websaeteng ea rona 'me u re romelle imeile ka ho toba!
