Hkringmang Daju a Critical Critical role gaw, Battery galaw ai lam hta kaja ai lam ni hpe tsi lajang ai lam: Superior Electrode Coatings a matu n bung ai hku galaw ai lam hpe madi shadaw ya ai.
N-gun n-gun grau law ai, n-gun grau galu ai, lithium-}ion battery ni hta shim lum lam hpe grau kaja hkra galaw ai lam ni gaw, electrode galaw ai lam a hkam kaja lam hte hkrak ai lam hpe n-mu yu ai sha, myit maju jung ai lam hpe tawn da ya ai. Ndai lam hta ahkyak ai, raitim, n yu n hkan galaw ai lam langai gaw, n-gun rawng ai hka htung ni hpe shinggyin la ai ni (cathode a matu aluminum, anode a matu magri) ni hpe ntsa kaw nna hkyen lajang ai lam rai nga ai. Ndai laika buk gaw, n-gun kaba ai{3}}efficiency tsi ladat ni a ahkyak ai lit hpe, langai sha re ai npu ntsa shamu shamawt ai lam hpe lu la na matu sawk sagawn ai, dai gaw, coating adhesion hpe grau kaja hkra galaw ai, kata na ninghkap ai lam hpe shayawm ya ai, hpang jahtum e, grau kaja ai battery galaw ai lam ni hpe hkrak hkrak matut mahkai ya ai.
1. Battery Electrode galaw shapraw ai hta hkan nang hkan sa ai lam
Battery coating galaw ai shaloi, n-gun rawng ai arung arai ni lawm ai slurry (ga shadawn, NMC, LFP, Graphite, Graphite), conductive additives, hte binders ni hpe n-gun n rawng ai nhprang arai ni hta bang da ai. Ndai foil ni a shingra tara ntsa na chemistry gaw non{3}polar hte hydrophobic rai nna, hka lim ai lam n kaja ai hte n-gun kya ai n-gun hpe polar solvent- kaw nna n-gun kya ai hku n-gun kya ai hku byin shangun ai.
N kaja ai lam gaw, hkra machyi ai lam law law hta dan dawng nga ai:
Delate galaw ai lam:Dai coated active material gaw calendering (rolling), sliting, shing nrai cell hpawng de ai shaloi foil kaw na tsan mat chye ai.
Internal ninghkap ai lam law wa ai:Dai coating hte foil lapran na Microscopic gap ni gaw electron hpe htawt sit ya ai majaw, cell a pat shingdang ai lam hpe sharawt ya ai.
Atsam n-gun yawm ai hte hkrat sum ai lam:Delaminated particles ni gaw electrochemical n shamu shamawt ai, shayawm ai atsam, shing nrai, kata na short circuit ni hpe shabyin ya lu ai.
Hpaga lam hta hkra machyi ai lam ni:N kaja ai hka lim ai lam gaw, n bung ai coating garan ginhka ai lam, pinholes, hte streaks ni hpe shabyin ya ai, n-gun n rawng ai hku galaw shapraw ai lam hpe shabyin ya ai.
Ndai hpe tawt lai lu na matu, npu na n-gun hpe jat wa na matu, npu na n-gun hpe jat wa na matu, slurry gaw maren mara garan nna, n-gun ja ai hku matut mahkai lu na matu ra sharawng ai.
2. Corona tsi lajang ai lam: Nbung laru n-gun n-gun .
Corona tsi gaw nbung laru plasma hpaji masa rai nna, hkum hkrang hte chemical hku nna galai shai ai lam ni hpe n galai shai ai sha, hkum hkrang hte chemical galai shai shangun ai. Dai foil gaw grounded roller ntsa hku lai wa ai shaloi, tsaw ai{1}}}voltage gaw, shi a ntsa kaw loi mi jung da nna, grup yin nbung hpe ionize galaw ai.
Ndai lam gaw, n-gun ja ai amyu bawsang ni a cocktail lawm ai plasma a shingnip shingna hpe shabyin ya ai:
Ions:Positive hte n kaja ai ions ni.
Electron ni:High{0}}energy n lawm ai electron ni.
Radical ni:Atom ni hte molecule ni hpe grai n-gun ja hkra galaw ai.
UV Nhtoi:Myit rawt ai gas molecule ni kaw na pru wa ai.
Ndai plasma gaw metal foil a polymer-rich oxide layer hpe hkra machyi shangun ai shaloi, madung ladat lahkawng byin pru wa ai:
1. Chemical modification:Reactive oxygen amyu bawsang ni gaw, npu kaw na prat tup na covalent bonds (carbon-oxygen hpung ni hpe hpaw ya ai. Ndai lam gaw ntsa na n-gun hpe grai jat shangun nna, hka hpe grai shayawm ya ai.
2. Hkum hkrang hte seng ai lam:Dai n-gun ja ai bawm jahkrat ai lam gaw, npu hpe n-gun n rawng hkra galaw ya nna, slurry kata na binder hte mechanical interlocking galaw na matu, akyu rawng ai lamu ga hpe jat ya ai.
Dai majaw, n-gun ja ai slurry hpe lang na matu hte n-gun ja ai hku n-gun ja ai hku galaw na matu hkum tsup ai hku npawt nhpang langai mi rai nga ai.
3. Lam Hpe Hkrang Shap
Corona treaters yawng hpe maren sha n galaw ai. Battery galaw ai lam hta ra kadawn ai makau grup yin a matu, tsaw ai-efficiency system gaw, lam law law hpe galaw ra ai:
A. N bung ai tsi lajang ai lam hpe kahkyin gumdin ai lam
Madung ra kadawn ai lam gaw web width hte length ting hta n bung ai lam rai nga ai. Gara shara hta mung n-gun kya ai shara byin wa chye ai. Advanced system ni gaw ndai hku nna ndai hpe lu la ai:
Electrode hkrang shapraw ai lam:N tsi lajang ai shara ni a "lanes" hpe yeng seng kau ya ai n-gun n rawng ai electrode ni hpe garan tawn da ai.
Closed- Power Control:Real{0}} aten hpe yu reng ai hte n-gun dat pru ai lam hpe gram lajang nna, line lawan ai (sh) grup yin masa ni hta galai shai ai lam ni hpe gram lajang na matu.
Uniform Air Gap hpe hkang ai:Electrode hte shamu shamawt nga ai web lapran hta n bung ai tsan gang ai lam hpe n-gun jaw na matu, n-gun rawng ai jak hkrang hkrang shapraw ai lam.
B. N-gun atsam n-gun hte n-gun atsam hpe hparan ai lam
Battery foil ni gaw grai n-gun n rawng ai hte katsi ai hpe hkam sha chye ai. Grai katsi ai gaw foil hpe n kaja ai, arnealing, shing nrai, daw mat ai pyi byin shangun chye ai.
Ngwi pyaw ai-State Power Supplies ni:Dai ni na aten hta, n-gun ja ai{0}} n-gun ja ai ni gaw, n-gun n rawng ai n-gun atsam hpe n-gun n law ai sha jaw ya ai.
Advanced Cooling System ni:Hka- hpe electrode hte treater roll lahkawng yan a hka n-gun hpe shapraw kau nna, katsi ai hpe yeng seng kau na matu hte n-gun n rawng ai foil substrate hpe makawp maga na matu ahkyak ai.
Madung hku nna Plasma:Hpa majaw nga yang, n-gun dat ni gaw, diffuse n-gun hpe shabyin ai hta, plasma reaction hkum nan hta n-gun hpe hkrak hkra galaw ya ai.
C. Process hpe hpaw shalawm ai lam hte kam hpa mai ai lam
Battery coating lines ni gaw lawan ai hku hkawm nna, n-gun grau law ai hpe ra sharawng ai.
Robust Gawgap ai lam:Coating shara langai a n hkru n kaja ai makau grup yin hpe hkam sharang lu na matu, solvent n-gun hte particulate matter ni hpe ninghkap lu na matu galaw da ai.
Seamless Integration:Dai ni na aten na PLC ni hte SCADA masa ni hte htuk manu ai lam gaw, tengman ai{0}} aten na jahpan ni hpe ka da ai hte galaw sa wa ai lam hpe hkang zing na matu (Industry 4.0).

4. N-gun jaw ai. Battery galaw ai lam hte Yield hpe galaw shapraw ai lam hta hkra machyi ai
1990 ning hta
Electrochemical galaw ai lam hpe grau kaja hkra galaw ai:N-gun ja ai adhesion gaw matut mahkai ai lam hpe shayawm ya lu ai majaw, charge/discharge cycle ni hta grau kaja ai rate atsam hte n-gun yawm mat ai.
Grau kaja ai Mechanical Integrity:Tsi lajang da ai electrodes ni gaw, n-gun n rawng ai (sh) n-gun n rawng ai sha, calendering hte winding a stress ni hpe hkam sharang lu ai majaw, grau nna jak rung n-gun ja ai cell ni byin wa ai.
Production hpe jat wa ai Yeld:Coating- hte seng ai n kaja ai lam ni hpe grai shayawm ai gaw, grau law ai pru wa ai lam de hkrak sha gale mat nna, n-gun yawm ai lam ni hpe shayawm kau ya ai.
Aten galu{ 0}}TaActive material garan ginhka ai lam hpe pat shingdang ai hku nna, battery gaw latsa jan na cycle ni hta shi a shawng na atsam hpe grau law hkra tawn da ai.
5. Dawdan ai lam
Wan jak mawdaw hte bai gram lajang mai ai n-gun hpe shinggyin tawn da ai gat lawk ni kaba wa ai hte maren, battery galaw ai hta shut ai lam a majaw n-gun yawm mat ai. Process step shagu hpe quality hte consistency a matu grau kaja hkra galaw ra ai. High{2}}efficiency corona tsi lajang ai lam gaw hkyen lajang ai lahkam langai sha n rai; dai gaw, tsaw ai- bungli galaw ai lam, kam mai ai lithium-ion battery ni hpe shapraw na matu npawt nhpang hpaji langai mi rai nga ai. Dai gaw, n-gun n-gun hpe n-gun jaw ai lam hpe madi shadaw ai hku nna, electrode coating hte current mahkawng da ai wa lapran hta kaja dik htum ai hku hkau lam hpe madi shadaw ya ai, hpang na prat na shim lum ai, galu ai-lating, n-gun ja ai n-gun hpe shinggyin la lu ai hparan ladat ni a matu npawt nhpang hpe gawgap ya ai. Dai majaw, n-gun ja ai ntsa lam hpe tsi lajang ai hpaji masa hta gumhpraw bang ai gaw, battery a bungli galaw ai lam hte asak galu ai lam a matu gumhpraw bang ai lam rai nga ai.
