Kugadzirwa kwemabhatiri e lithiamuinzira ye "roll-to-roll". Ingave iri bhatiri re lithium iron phosphate, bhatiri re sodium-ion kana bhatiri re ternary, rinofanira kupfuura nepakati penzira yekugadzirisa kubva pafirimu diki kuenda kubhatiri rimwe chete, uyezve kuenda kuhurongwa hwebhatiri. Maitiro ekugadzirira mabhatiri e lithium anogona kukamurwa kuita zvikamu zvitatu: kugadzirwa kwe electrode sheet, kugadzirwa kwemasero, uye kurongedza makemikari.
Kune maitiro akati wandei akakosha mumaitiro matatu makuru aya, ayo anokanganisa zvakananga kugona kwekuchengetedza simba rebhatiri, kuchengetedzeka kwechigadzirwa uye hupenyu hwebasa. Nokudaro, mashandiro emabhatiri anogadzirwa nemaitiro akasiyana ekugadzira anosiyana zvikuru. Mune aya malink,kuchenesa nelaserparizvino vanogona kutora chikamu muzvirongwa zvekugadzirira zvinopfuura gumi nemaviri, izvo zvinogona kuvandudza zvakanyanya mwero wemhando yemabhatiri e lithium.

Sezvo kudiwa kwemabhatiri emagetsi kuri kuramba kuchiwedzera, kudiwa kwekuchenesa nelaserMidziyo ichawedzerawo. Tevere, tichatarisa pane mamwe maitiro ekushandisa uye zvakanakira kuenzanisa.
1. Kucheneswa kwemhangura nearuminiyamu ne laser usati waisa danda rekuvhara
Maelectrode akanaka neasina kunaka ebhatiri re lithium anogadzirwa nekuputira maelectrode akanaka neasina kunaka ebhatiri re lithium pafoil yealuminium nefoil yemhangura. Kana zvidimbu, marara, guruva nezvimwe zvinhu zvikasanganiswa panguva yekuputira, zvinokonzeresa micro-short circuit mukati mebhatiri, uye muzviitiko zvakakomba, bhatiri rinobatira moto roputika.
Saka, foil inofanira kucheneswa isati yaiswa pendi kuti ive nepamusoro pakachena chose, pasina oxide.
Zvidimbu zvebhatiri zviripo zvinowanzo chenurwa nemafungu e ultrasonic, uye ethanol solution inoshandiswa senzira yekuchenesa isati yaiswa pendi. Maitiro aya ane zvikanganiso zvinotevera:
1. Pakuchenesa zvikamu zvesimbi zvesimbi, kunyanya zvidimbu zvealuminium alloy, zvinokanganiswa nefrequency, nguva yekuchenesa uye simba, cavitation effect yemafungu eultrasonic inogona kukanganisa nyore nyore aluminium foil, zvichiita kuti pave nemaburi matete. Nguva yekushanda yakareba, maburi anokurawo.
Foil inoshandiswa pachinhu chebhatiri re lithium inowanzova foil isina chinhu ine ukobvu hwe 10 μm, iyo inonyanya kukonzera maburi nekuda kwematambudziko ekuchenesa.
2. Kushandiswa kwe ethanol solution semushonga wekuchenesa hakusi nyore chete kukonzera kukuvara kwezvimwe zvikamu zve lithium battery, asiwo kunogona kukonzera "hydrogen embrittlement", izvo zvinokanganisa mashandiro e aluminium foil.
3. Kunyangwe kuchenesa kwacho kwakaipa kupfuura kuchenesa kwemakemikari echinyakare, kuchena kwacho hakuna kunaka sekuchenesa nelaser. Dzimwe nguva kuchine zvinhu zvinosvibisa pamusoro, izvo zvinoita kuti pendi yacho iparadzane nefoil kana kuti iburitse maburi ekupwanyika.
Senzira yekuchenesa isina zvinhu zvinoshandiswa, kuchenesa nelaser hakuna kukanganisa zvachose panyaya yekuchena uye kuchenesa pamusoro pealuminium foil, zvichiita kuti saizi nependi yedanda zvishande zvakanaka.
Kushandisa foil yesimbi yekuchenesa nelaser hakungogone chete kuvandudza kushanda kwekuchenesa nekuchengetedza zviwanikwa zvekuchenesa, asiwo kugadzirisa kutarisa data rekuchenesa panguva chaiyo uye kuona huwandu hwemhedzisiro yekuchenesa, izvo zvinogona kuvandudza kuenderana kwekugadzirwa kwematanda akawanda.
2. Kuchenesa ma bhatiri ne laser usati wabatanidza
Matabhu acho isimbi dzinoburitsa maerekitironi akanaka neasina kunaka kubva musero rebhatiri, uye ndiwo mapoinzi ekubata kana bhatiri rachajwa uye raburitswa. Zvinhu zvinosvibisa pamusoro zvakaita semafuta, zvinodzivisa ngura nezvimwe zvinhu zvinogona kukonzera matambudziko akadai sekupwanyika kusina kunaka, kutsemuka uye maburi ari musero.
Kuchena kwenzvimbo inobatwa nemagetsi kunogona kukanganisa zvikuru kuvimbika uye kugara kwenguva refu kwekubatana kwemagetsi.
Kuchenesa ma electrode kuripo kunonyanya kushandisa kuchenesa nemaoko, kuchenesa nemakemikari akanyorova kana kuchenesa neplasma:
● Kuchenesa nemaoko hakuna kunaka uye kunodhura;
● Kunyangwe tambo yekuchenesa mvura inonyorova ichivandudza mashandiro, kureba kwetambo kwakareba, inogara munzvimbo yakakura yefekitori, uye mushonga wemakemikari uri nyorewo kukuvadza zvimwe zvikamu zvebhatiri re lithium;
● Kunyange zvazvo kuchenesa plasma kusingade mvura yemumvura, kunodawo gasi rinoshandiswa sezvinhu zvinodyiwa, uye gasi rinoita kuti maerekitironi akanaka neasina kunaka ebhatiri avhurike zviri nyore. Pakushandisa, zvinowanzodiwa kutenderedza bhatiri kakawanda kuti uparadzanise maerekitironi akanaka neasina kunaka ekuchenesa. Kushanda chaiko hakusi kwakakwirira.
Kuchenesa neLaser kunogona kubvisa tsvina, guruva zvinobudirira, nezvimwewo. pamucheto wedanda rebhatiri, uye gadzirira kusonera mabhatiri pachine nguva.
Nekuti kuchenesa nelaser hakudi zvinhu zvinodyiwa zvakaita sezvisina kusimba, zvemvura uye zvegasi, chimiro chacho chakaoma, nzvimbo inogarwa idiki, uye mhedzisiro yekuchenesa inoshamisa, izvo zvinogona kuvandudza zvakanyanya kutenderera kwekugadzira uye kuderedza mutengo wekugadzira;
Inogona kukwesha pamusoro pewelding zvichibva pakubvisa zvinhu zvipenyu netunhu tudiki, uye kuvandudza kuvimbika kwewelding yelaser inotevera. Ndiyo imwe yesarudzo dzakanakisa dzekuchenesa matabhu.
3. Kuchenesa namatidziro yekunze panguva yekubatanidza
Kuti mabhatiri e lithium asakwanise kuchengetedzeka, zvinowanzodiwa kuisa guruu kumaseru e lithium kuti riite basa rekudzivirira kupisa, kudzivirira mashort circuits, kudzivirira macircuits, uye kudzivirira kukwenya.
Kana firimu rekunze resero risina kuchena rikaedzwa neCCD, pachava nemakwinya, maburi emhepo, mavanga nezvimwe zvikanganiso pakuonekwa, uye maburi emhepo ane dhayamita ye ≥ 0.3mm anogona kuonekwa kazhinji. Pane mukana wekubuda kwemvura uye ngura, izvo zvinoderedza hupenyu hwebhatiri uye zvinogonawo kuva nenjodzi dzekuchengetedza.
Kuchenesa neLaserinogona kusvika padanho reSa3 mukugona kuchenesa pamusoro pesero, uye mwero wekubviswa kwayo unodarika 99.9%; uye hapana kushushikana pamusoro pesero. Kana ichienzaniswa nedzimwe nzira dzekuchenesa dzakadai sekuchenesa kwe ultrasound kana kukuya kwemuchina, inogona kuve nechokwadi chekuti zviratidzo zvemuviri nezvemakemikari zvakaita sekuoma kwepamusoro pesero dzebhatiri hazvichinje zvakanyanya, uye kuwedzera hupenyu hwebasa rebhatiri.
Kuwedzera kune mienzaniso yataurwa pamusoro apa, kuchenesa nelaser kunewo zvimwe zvakanakira mune mamwe maitiro gumi nemaviri akadai sekubvisa pendi nemagetsi uye kuchenesa foil label.
Kana muchida kudzidza zvakawanda nezvekuchenesa nelaser, kana kuti muchida kutenga muchina wekuchenesa nelaser wakanakisisa, ndapota siyai meseji pawebhusaiti yedu uye titumirei email zvakananga!
