Kugadzirwa kwelithium mabhatirii "roll-to-roll" maitiro.Ingave iri lithium iron phosphate bhatiri, sodium-ion bhatiri kana ternary bhatiri, inoda kuenda kuburikidza nekugadzirisa kubva kufirimu rakatetepa kuenda kune rimwe bhatiri, uyezve kune bhatiri system.Iyo nzira yekugadzirira yemabhatiri e lithium inogona kukamurwa kuita matanho matatu: electrode sheet kugadzirwa, cell synthesis, uye kemikari kurongedza.
Pane akati wandei akakosha maitiro mune aya matatu maitiro makuru, ayo anozokanganisa simba rekuchengetedza simba rebhatiri, kuchengetedza chigadzirwa uye hupenyu hwesevhisi.Naizvozvo, kuita kwemabhatiri anogadzirwa nenzira dzakasiyana dzekugadzira kunosiyana zvakanyanya.Mune aya links,laser kuchenesaikozvino inogona kutora chikamu mune zvinopfuura gumi nemaviri maitiro ekugadzirira, ayo anogona kuvandudza zvakanyanya chiyero chemhando yemabhatiri e lithium.

Sezvo kudiwa kwemabhatiri emagetsi kuri kuramba kuchiwedzera, kudiwa kwelaser kuchenesamidziyo ichawedzerawo.Tevere, isu tichatarisa pane mamwe maitiro ekushandisa uye mabhenefiti ekuenzanisa.
1. Laser kuchenesa mhangura uye aruminiyamu foil pamberi danda chidimbu coating
Izvo zvakanaka uye zvisina kunaka electrodes ye lithiamu bhatiri inogadzirwa nekuputira zvakanaka uye zvisina kunaka electrode ye lithiamu bhatiri pane aluminium foil uye foil yemhangura.Kana zvimedu, marara, guruva uye mamwe midhiya zvakasanganiswa mukuputira, zvinokonzeresa diki-pfupi dunhu mukati mebhatiri, uye mumatambudziko akaomarara, bhatiri richabata moto uye rinoputika.
Naizvozvo, iyo foil inoda kucheneswa isati yapfekedzwa kuti iwane nzvimbo yakachena, isina oxide.
Iwo aripo bhatiri pole zvidimbu zvinowanzocheneswa nemasaisai e-ultrasonic, uye mhinduro ye ethanol inoshandiswa semumiririri wekuchenesa senzira yekuchenesa isati yapfeka.Iyi nzira ine zvikanganiso zvinotevera:
1. Apo ultrasonically kuchenesa metal foil parts, kunyanya aluminium alloy workpieces, inobatwa nehuwandu, nguva yekuchenesa uye simba, iyo cavitation effect ye ultrasonic waves inogona kukanganisa nyore aluminium foil, zvichiita kuti zvive zvakanaka pores.Iyo yakareba nguva yekuita, iyo yakakura ma pores.
Iyo foil inoshandiswa yelithium bhatiri pole chidimbu kazhinji ndeye zero foil ine ukobvu hwe10 μm, iyo inowanzoda kubvarura mumakomba nekuda kwematambudziko ekuchenesa maitiro.
2. Kushandiswa kwe ethanol solution semugadziri wekuchenesa hakusi nyore chete kukonzera kukanganisa kune zvimwe zvikamu zve lithium battery, asiwo kunowanzoita "hydrogen embrittlement", iyo inokanganisa maitiro emagetsi ealuminium foil.
3. Kunyangwe kucheneswa kwacho kwakaipa kupfuura kucheneswa kwemakemikari echinyakare, hutsanana hausati hwanyatsonaka sehuya hwekuchenesa laser.Dzimwe nguva kune kuchiri kusvibiswa pamusoro, izvo zvichaita kuti kuvhara kuparadzaniswa kubva kune foil kana kuburitsa maburi ekuderera.
Sekucheneswa kwakaoma pasina zvinobatika, laser yekuchenesa iri padyo ne zero hurema maererano nehutsanana uye hydrophilicity yekugadziriswa kwepamusoro kwealuminium foil, kuve nechokwadi chekuita saizi uye kupfekedza pachidimbu chedanda kusvika pamwero mukuru.
Iko kushandiswa kwelaser yekuchenesa simbi foil haingogone kuvandudza mashandiro ekuchenesa uye kuchengetedza zviwanikwa zvekuchenesa, asi zvakare kumisikidza chaiyo-nguva yekutarisa yekuchenesa maitiro data uye kuwanda kutsunga kwekuchenesa mhedzisiro, iyo inogona kunyatso kuvandudza kuenderana kwekugadzirwa kwebatch. pole zvidimbu.
2. Laser kucheneswa kwebhatiri tabs isati yave welding
Matebhu isimbi mitsetse inoburitsa maelectrode akanaka neasina kunaka kubva musero rebhatiri, uye ndiwo mapoinzi ekusangana kana bhatiri rachajwa nekuburitswa.Kusvibisa kwepamusoro segirisi, corrosion inhibitors uye mamwe macompounds ari mukuita anogona kukonzera matambudziko akadai seasina kunaka welds, kuputika uye porosity mu weld.
Kuchena kwenzvimbo yekubatana kunogona kukanganisa zvakanyanya kuvimbika uye kusimba kwekubatanidza magetsi.
Iyo iripo electrode yekuchenesa kazhinji inotora kucheneswa kwemanyorero, kuchenesa makemikari akanyorova kana kuchenesa plasma:
● Kuchenesa nemaoko hakushandi uye kunodhura;
● Kunyange zvazvo mvura yemvura yekuchenesa mutsara inovandudza kushanda, kureba kwemutsara kwakareba, inotora nzvimbo yakakura yefekitari, uye kemikari inoshandiswa zvakare nyore kukuvadza zvimwe zvikamu zve lithium battery;
● Kunyange zvazvo kuchenesa kweplasma kusingadi mvura yepakati, inodawo gasi rinoshandiswa sechinhu chinodyiwa, uye gasi ionization ichaita kuti magetsi akanaka uye asina kunaka ebheteri ashandurwe nyore nyore.Paunenge uchinyorera, zvinowanzodikanwa kufinya bhatiri kakawanda kuti uparadzanise ma electrode akanaka uye asina kunaka ekuchenesa.Iko kunyatsoshanda Kwete yakakwirira.
Laser kuchenesa kunogona kunyatsobvisa tsvina, guruva, nezvimwewo pamagumo ebheteri pole, uye gadzirira bhatiri welding mberi.
Nekuti kuchenesa laser hakudi chero chinodyiwa senge chakasimba, mvura uye gasi, chimiro chakabatana, nzvimbo inogarwa idiki, uye kuchenesa maitiro kunoshamisa, izvo zvinogona kuvandudza zvakanyanya kutenderera kwekugadzira uye kuderedza mutengo wekugadzira;
Inogona kuomesa iyo welding pamusoro pahwaro hwekunyatsobvisa organic zvinhu uye zvidiki zvidimbu, uye kugadzirisa kuvimbika kweinotevera laser welding.Ndiyo imwe yeakanakisa sarudzo dzekuchenesa tebhu.
3. Kuchenesa kwekunze kwekunamatira panguva yekuungana
Kuti udzivise tsaona dzekuchengetedza mabhatiri e-lithium, zvinowanzodikanwa kuisa glue kumasero e-lithium bhatiri kuita basa rekudzivirira, kudzivirira mapfupi maseketi, kudzivirira maseketi, uye kudzivirira zvikwambo.
Kana iyo firimu yekunze yesero isina kuchena ichiedzwa neCCD, pachava nemakwinya, mabhubhu emhepo, zvigwere uye zvimwe zvikanganiso pakuonekwa, uye mabhuru emhepo ane dhayamita ye ≥ 0.3mm anogona kazhinji kuonekwa.Pane mukana wekudonha uye ngura, izvo zvinoderedza hupenyu hwebhatiri uye zvakare zvine njodzi dzinogona kuitika.
Laser kuchenesainogona kusvika paSa3 level mukukwanisa kwekuchenesa kwesero pamusoro, uye chiyero chekubvisa chinopfuura 99.9%;uye hapana kunetseka pamusoro pesero.Kuenzaniswa nedzimwe nzira dzekuchenesa dzakadai se ultrasonic kuchenesa kana mechanical grinding, inogona kuve nechokwadi kuti zviratidzo zvemuviri uye zvemakemikari zvakadai sekuoma kwepamusoro kwemasero ebheteri haashanduki kusvika pamwero mukuru. , uye kuwedzera hupenyu hwebasa rebhatiri.
Pamusoro pemienzaniso yataurwa pamusoro apa, laser yekuchenesa zvakare ine yakanakira mamwe mabhenefiti mune mamwe gumi nemaviri maitiro akadai sebhatiri chivharo chekubvisa pendi ye electrophoretic uye foil label yekuchenesa.
Kana iwe uchida kudzidza zvakawanda nezve laser yekuchenesa, kana uchida kukutengera yakanakisa laser yekuchenesa muchina, ndapota siya meseji pane yedu webhusaiti uye titumire email zvakananga!
