Lithium-ion battery electrode hpe n-gun jaw ai gaw hpa rai ta?
Electrode Slitting ladat ni
Slitting hpe jak rung bungli galaw ai hta shearing ngu shamying ma ai, dai hpe htu ai ladat ni a hkrang hte maren, oblique-blade hka htung zawn re ai hka htung ni hpe garan nna, flat{1}}}blade zawn re ai hka lim ai ladat ni hku nna garan mai ai, n-gun n rawng ai hka lim ai lam, rotary shearing (sh) roll cutting), disc shearing.
Ollique-blade ni a n-gup magap hta, ntsa hte lawu maga lapran hta ngang grin ai angle nga ai, n-gun rawng ai angle gaw, madung hku nna 1℃~ 6℃rai nga ai. Madung hku nna, ntsa na n-gup magap gaw n-gup magap n-gun rawng ai, sumla 7-2(a). Ntsa hte lawu na blade ni gaw parallel n re ai majaw, cutting way makau kaw n-gun nga ai, dai gaw cutting edge hpe loi loi hte galai shai kau ya ai. Raitim, shearing area gaw kaji ai, shearing n-gun hte n-gun lang ai lam gaw flat-} yawng lang ai hka htung hta kaji ai majaw, n-gun kaba ai hte lapran tsang na shearing jak ni hta n-gun ja ai plate ni hpe shearing galaw na matu lang ai, dai hpe electrode slitting galaw na matu n lang ai.
Flat- a n-gup magap gaw oblique-} a n-gup magap hte maren sha nga ai, ntsa hte lawu na shingnip shingna ni gaw bung ai hta lai nna, sumla 7-2(b) hta madun da ai hte maren rai nga ai. Dai gaw, n-gun n rawng ai sha, n-gun n rawng ai sha, n-gun n rawng ai hku htu lu ai, raitim, hka htung n-gun gaw kaba ai, law malawng gaw, shearing jak kaji ni hta lang nna, n-gun n rawng ai plate ni hte sumla hkrung ni hpe shinggrup na matu [1-2], electrode cross-cutting galaw na matu mung lang ai.
Rotary shearing hpe arc-edge roll cutting ngu nna mung shamying ma ai, dai gaw arc-shaped edge lawm ai arung arai ni hpe lang ai. Dai arung arai ni gaw, sumla 7-2(c). Madung hku nna, masat da ai{6}}length cross{7}} hpe chye na na matu, bawnu hte n-gup lapran na cross-cutting, edge slitting galaw na matu jai lang ai. Madung hku nna, n-gun n-gun hte n-gun ja ai plate ni hpe shearing galaw ai shaloi, n-gun n law ai, n-gun n law ai, asak galu ai, hte n-gun kaba ai ni hpe madun dan ai[3].
Disc shearing hpe disc{0}}}shap da ai cutter leng lahkawng hpe matut manoi shinggrup ai hku nna ngut kre ai, lawu na langai hte lawu langai, sumla 7-3 hta madun da ai hte maren. Shearing galaw ai aten hta, n-hkap la ai electrode sheet gaw disc cutter hpaw ai shara de shang nna, cutting galaw ngut ai hpang strips law law hku garan ai[1]. Disc shearing hpe n-gun n rawng ai plate, n-gun n rawng ai sumla ni, magri mang ni hpe galu kaba hkra galaw na matu grai lang ma ai.
Lithium-ion battery ni hpe galaw ai shaloi, electrode sheet ni hpe galu kaba ai hku gang je kau ai (slitting) hpe lang ai shaloi, disc shearing hpe lang chye ai, cross{1}}ttingting gaw flat- yawng lang ai. Automated galaw ai line ni gaw, shawng nnan e slitting galaw nna, dai hpang cross{4}}}culeting galaw chye ai. Madung hku nna, lawu na ra kadawn ai lam ni hpe lithium-ion battery electrode sheets ni hpe slitting galaw ai shaloi tawn da ai:
① Electrode sheet a shadawn shadang hkrak ai lam;
② Electrode sheet jut ni gaw n-gun n rawng ai hte n-gun n rawng ai, n-gun n law ai, electrode coating layer gaw n hkrat sum ai;
③ High yield hte galaw shapraw ai atsam grai law ai.

Plastic arung arai ni a matu, shearing galaw ai lam hpe daw masum hku garan mai ai[5-6]:
① Dai nhtu gaw plate kata de bang hpang wa nna, garan ai lapran na plate a arai gaw plastic n-gun n rawng ai hte lwi ai plastic n-gun n-gun gaw plastic strain a shadawn sharam de du hkra lwi nga ai. Ndai hpe shawng na daw ngu shamying ma ai. Ndai aten laman, plate arung arai ni hpe hka ja nna, n-gun rawng ai shear surface hpe gawgap da ai, sumla 7-4(a) hpe yu u.
② Dai blade gaw, plate kata de matut nna dip bang nna, n-gup magap n-gup magap lapran na plate arung arai ni hta, n-gup n-gu, n-gup n-gu 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 dat ai. Dai daw ni a lapran na plate arung arai ni gaw, ntsa hte lawu blade ni gaw, npu hte lawu blade ni langai sha hta nga ai aten du hkra, tensile stress a action npu hta, htum mat ai. Ndai hpe lahkawng ngu na daw ngu shamying ma ai. Ndai aten hta, plate arung arai ni htum mat nna, nsam nsam n bung ai daw hpe hpaw da ai, sumla 7-4(b) hte (c) hte (c) hpe yu u;
③ Dai nhtu gaw matut nna dip nga ai. Plastic lwi ai majaw, cuts lapran na plate a arai hpe blade ni shinggrup da ai gap kaji de shapraw kau ai. Dai blade cut ni a overlap law wa ai hte maren, gap kata na plate arung arai ni hpe gang je kau nna gang je kau nna, jut kaw burr ni byin wa ai, sumla 7-4(d) hpe yu u, dai arung arai ni garan pru ai aten du hkra. Ndai hpe bur byin pru wa ai aten ngu shamying ma ai. Dai arung arai ni hpe garan ginhka ai shaloi, dai arung arai ni gaw, plate a arai ni hpe n-gun n rawng ai (sh) dan dawng hkra galaw ya lu ai majaw, dull fracture ntsa na morphology hte burrs ni galai shai wa ai, raitim galai shai ai lam gaw kaji ai.
Ka-ang hkup htu ngut ai hpang shear cross{0}} daw hpe sumla 7-5 hta madun da ai, dai hta daw masum lawm ai: n-gun n rawng ai shear surface, dull fracture ntsa, n-gup magap hpe burr[5-6]. Dai dull fracture ntsa hpe mung, n-gun n rawng ai daw hpe mung shamying ma ai. Shi a galu kaba ai lam gaw, dai arai a plasticity hte seng ai. Plasticity grau kaja ai arung arai ni a matu, dull fracture ntsa gaw kaji ai, n-gun rawng ai shear surface gaw grau kaba ai, magri lwi ai lam gaw grau law ai majaw, burr ni grau law hkra byin wa ai. Dai hte maren, n-gun n rawng ai arung arai ni a matu, n-gun n rawng ai shear surface n nga ai.
