Ahkyak ai, raitim, law law lang n yu n hkan galaw ai, electrode galaw shapraw ai lam hta lahkam mi gaw, active material coating hte ya na mahkawng da ai ni a lapran na matut mahkai lam rai nga ai. N kaja ai hku n-gun n rawng ai majaw, n-gun yawm mat ai, kata na ninghkap ai lam ni law wa ai, tsin-yam kaba byin wa ai. Ndai laika buk gaw, n-gun kaba ai{4}} n-gun atsam corona tsi ladat hpe grai kaja ai, katsi katsang, grup yin hpe makawp maga ai ladat hku nna jai lang ai lam hpe sawk sagawn ai rai nna, dai hku nna, n-gun ja ai n-gun hte hka lim ai lam hpe grau kaja hkra galaw ya lu ai, dai hku nna, hpang na- n-gun rawng ai battery ni a matu grau kaja ai coating adhesion hpe hkam la lu na matu re.
1. Npawt Nhpang: Battery hpe galaw shapraw ai hta hkan nang hkan sa ai lam
Dai zawn re ai n-gun rawng ai arung arai ni a n-gun n rawng ai arung arai ni (ga shadawn, Lithium Cobalt Oxide a matu Lithium Cobalt Oxide, arode ni a matu Lithium Cobalt Oxide) hpe n-gun n rawng ai hku n-gun n rawng ai hkrang langai mi rai nga ai. Ndai coated layer a dinghpring ai lam gaw ahkyak dik rai nga ai.
Foil- hpe n-gun n rawng ai hku n-gun n rawng ai hku n-gun rawng ai gaw:
Delate galaw ai lam:Dai coating gaw calendering, slitting, shing nrai cell hpawng de ai shaloi foil kaw na garan pru ai.
Resistance jat wa ai:N kaja ai matut mahkai lam gaw, lapran na wan n-gun hpe ninghkap ai lam hpe sharawt ya nna, n-gun dat shapraw ai lam hte n-gun hpe shayawm ya ai.
Atsam n-gun yawm ai & Cycle Prat hpe shayawm kau ai:Isolated active material particles ni gaw electrochemical hku nna n shamu shamawt ai majaw, lawan ai hku n-gun yawm mat ai.
Hkamja lam HazSafety Hazards;Delamination gaw hotspot ni hte kata na short circuit ni hpe shabyin ya lu ai majaw, thermal hprawng ai lam hpe shabyin ya lu ai.
Adhesion hpe grau kaja hkra galaw na matu htunghking ladat ni gaw binder chemistry hte calendering pressure hpe grai kam hpa nga ai. Raitim, ndai ladat ni gaw shadawn sharam ai lam ni nga ai hte npawt nhpang manghkang hpe n hparan ya lu ai: n-gun n rawng ai nhprang dat ni a npu na n-gun n-gun, dai ni gaw hka lim ai sau hte oxides ni hte n-gun n rawng ai majaw, hka n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun ni hpe n-gun jaw ya ai.
2. High High{1}}Corona a tsi lajang ai lam
Corona tsi ladat gaw nbung kata na plasma hpaji masa rai nna, tsi lajang da ai arung arai langai hpe shinggrup da ai nbung hpe ionize galaw na matu, n-gun kaba ai wan n-gun pru ai wan n-gun hpe jai lang ai. 1990 ning hta,
Ladat:Dai metal foil web gaw grounded roller ntsa hku lai wa ai. Dai hta n-ga, tsaw ai- law law hte matut da ai electrode langai gaw, tsaw ai{2}}voltage n-gun dat shapraw ai jak gaw, n-gun ja ai electrostatic field hpe shabyin ya ai. Ndai ginra gaw grup yin na nbung (O₂, N₂, H kaji) hpe ionize galaw ya ai, ion, electron, free radicals, hte myit rawt ai molecule ni lawm ai plasma a n-gun ja ai sumwi hpe shabyin ya ai (ozone zawn ozone zawn re ai ozone zawn re ai).
Surface Modification Mechanism:Ndai plasma gaw foil a ntsa hpe hkra machyi shangun ai shaloi, madung mabyin lahkawng byin pru wa ai:
1. NdunNtsa na san seng ai lam:Dai n-gun ja ai plasma amyu ni gaw, n-gun n rawng ai sau hte nhprang arai ni zawn re ai, n-gun n rawng ai n kaja ai arung arai ni hpe atsawm sha vaporize galaw nna, shapraw kau ya ai.
2. Surface Activation:Grau ahkyak ai gaw, plasma gaw polar bungli hpung ni hpe (madung hku nna hydroxyl -OH, carbonyl C{1}O, hte carboxyl {2}COOH) hpe n-gup magap a ntsa de oxidation reactions hku nna hpaw hpang wa ai. Ndai ladat hpe functionalization ngu shamying ai, ntsa na chemistry hpe prat tup galai shai kau ya ai.
3. Battery Electrode galaw shapraw ai lam a matu madung akyu ara ni
Dai majaw, n-gun kaba ai{0}} n-gun kaba ai corona treater hpe coating line de hkrak sha bang ya ai gaw, ahkyak ai akyu ni hpe jaw ya ai:
Surface Energy hta Dradic law jat wa ai:Polar hpung ni hpe hpaw hpang ai gaw, npu na n-gun hpe npu na-energy kaw nna galai shai shangun ai, n-gun n rawng ai-hkawm tsaw ai shara de galai shai kau ya ai, n-gun rawng ai, hydrophilic langai mi de galai shai kau ya ai. Ndai lam gaw, electrode slurry a hka lim ai lam hte kap bra ai lam hpe grai kaja hkra galaw ya nna, grau bung ai, pinhole- n lawm ai shingnip hpe galaw ya lu ai.
Superior Adhesive n-gun atsam:Dai zawn re ai n-gun atsam ni hpe n-gun jaw ai lam ni hpe n-gun jaw ai lam ni hpe n-gun jaw ai lam ni hpe n-gun jaw ai lam ni hpe n-gun jaw ai. Ndai lam gaw, katsi ai, calendering, hte galu kaba ai{1}} aten galu ai electrochemical cycle jawn ai lam ni a myit ru myit tsang lam ni kaw na lawt lu ai ngang kang ai matut mahkai lam hpe lu la shangun ai.
Hkamja lam hpe n-gun jaw ai lam & Yield:N-gun rawng ai hte shamu shamawt ai shara hpe jaw ya ai hku nna, corona tsi gaw galai shai ai foil quality a majaw byin pru wa ai batch-batch galai shai ai lam hpe yeng seng kau ya ai. Ndai lam gaw scrap rate hpe shayawm ya nna, galaw shapraw ai lam yawng hpe grau kaja hkra galaw ya ai.
Hka wa u, n-gun n-gun hpe n-gun jaw ai, hte Instanteous:Chemical primers (sh) wan hkru ai lam hte n bung ai sha, corona tsi gaw san seng ai ladat re. Dai hta hka n-gun n rawng ai, hka n-gun n rawng ai, shi a akyu gaw kalang ta byin pru wa ai majaw, n-gun kaba ai-speed matut manoi galaw shapraw ai ladat ni a matu grai kaja ai.
Advanced arung arai ni hte htap htuk ai lam:Dai hpaga lam gaw grau htum ai electrode ni, silicon-anodes de sit sa wa ai shaloi, hkum tsup ai interfacial adhesion hpe ra sharawng ai lam grau nna ahkyak wa ai. High{3}} n-gun n-gun hpe tsi lajang ai lam gaw ndai arung arai nnan ni hpe hkan nna htuk manu ai arung arai langai mi rai nga ai.
4. Hkrang shapraw ai lam ni hpe myit yu ai lam
Hkrak ai- n-gun kaba ai corona treater a akyu hpe grau law hkra lu la na matu, lam law law hpe grau kaja hkra galaw ra ai:
Power Density:N-gun grau law ai (W/min/m2 hta shadawn ai) gaw denser plasma hpe shabyin ya ai majaw, ntsa lam hpe grau nna shamu shamawt shangun ai. Hpang maga de tsi lajang ai (sh) loi mi n-gun n rawng ai tsi lajang ai lam hpe koi lu na matu kaja dik ai madang hpe dawdan ra ai.
Electrode hkrang shapraw ai lam:Web width hte zonal hpe hkang ra ai hta hkan nna, Standard (sh) segmented electrode ni hpe lang mai ai.
Website Speed & Integration:Dai system hpe ya nga ai coater kata de n-gun n rawng ai sha hpaw shalawm ra ai, line tension hpe n jahten ai sha, n-gun n-htum ai hku tsi lajang ai lam hpe n-gun jaw na matu web speed hte synchroning galaw ra ai.
Ozone Management:Dai ni na aten na tsi sarawun ni gaw, byin pru wa ai ozone hpe shim lum ai hku hkra machyi hkra, shim lum ai bungli galaw ai makau grup yin hpe hkam la lu na matu, hpawng de da ai ozone jahten sharun ai unit (ODUs) ni hpe bang da ai.
5. Dawdan ai lam
Battery galaw ai lam hta grai shingjawng ai masa hta, bungli galaw ai lam hte kam hpa mai ai lam hta n-gun n rawng ai akyu ni hpe lu la na matu ahkyak nga ai. High{1}} n-gun n-gun corona tsi ladat gaw, ya aten na mahkawng da ai ni a npu na n-gun ni hpe molecular madang hta engineering hku nna, npawt nhpang galaw shapraw ai lam hpe hparan ya ai. Coating hte substrate lapran hta n-gun n rawng ai hku n-gun n rawng ai hku matut mahkai ai lam hpe hkam la ai hku nna, dai gaw atsam grau law ai, daw jau ai prat hpe grau galu ai, shim lum ai shara ni hpe grau kaja hkra galaw lu ai battery ni hpe galaw shapraw na matu hkrak sha karum ya ai. Dai zawn re ai hku nna, dai gaw galaw sa wa na lahkam langai sha n rai, rawt jat galu kaba wa ai n-gun atsam hpe shinggyin tawn na matu ra kadawn ai hpaji masa langai mi rai nga ai.
