Lithium ion battery ni a shimlum lam hpe gara hku gram lajang na kun?
N-gun n-gun mawdaw nnan ni a akyu gaw, shanhte gaw grau npu na-carbon rai nna, gasoline a wan n-ga-loi ai mawdaw ni hta grau nna n-gun n rawng ai. Dai gaw, n-gun n-gun n-gun n-gun n-gun ni hku nna, lithium battery, hydrogen wan sau, etc. zawn re ai n-gun n-gun ni hpe jai lang ai. Lithium ion battery ni hpe mung grai lang ai, n-gun n-gun mawdaw nnan ni, mobile phone ni, laptop ni, tablet ni, mobile power, mobile power, wan n-gun, wan jak ni hte kaga ni hpe mung lang ai.
Raitim, lithium ion battery a shimlam manghkang hpe n mai shayawm kau ai. Accident law law hta masha ni n tara ai hku charge galaw ai (sh) grup yin na nbung katsi ai lam grai law ai shaloi, tinang hkrai wan hkru ai lam hte lithium ion battery hpe shapraw kau na matu loi ai hpe mu lu ai, dai gaw lithium ion battery byin pru wa ai hta grau kaba ai machyi makaw langai mung rai nga ai.
Lithium battery a shingra tara gaw shi a "hpyen n-gun" hpe dawdan ya ai raitim, hkrit tsang hpa hte shim lum lam hpe shayawm na matu tsep kawp n mai byin ai. Battery hpaji masa matut manoi rawt jat wa ai hte, mobile phone hpaga hpung ni (sh) n-gun n-gun mawdaw company nnan ni rai tim, battery hparan ai ladat hte katsi ai hpe hkang ai ladat hku nna rai tim, battery gaw shim lum lam hpe madi shadaw ya lu ai, bawm kapaw ai lam (sh) shi hkum shi wan hkru ai lam n nga na re.
1. electrolyte a shimlum lam hpe grau kaja hkra galaw na
grau nna nbung katsi ai shara hta, electrolyte hte kaja ai hte n kaja ai electrode ni a lapran hta grai law ai reactivity nga ai. battery a shimlum lam hpe grau kaja hkra galaw na matu, electrolyte a shimlum lam hpe grau kaja hkra galaw na matu grau kaja ai ladat langai rai nga ai. Magam bungli galaw ai additives ni hpe jat bang ai hku nna, lithium sau nnan ni hpe jai lang nna, solvent nnan ni hpe lang ai hku nna, electrolyte a shimlum lam hpe atsawm sha hparan lu na re.
Additives ni a magam bungli amyu myu hku nna, lawu na garan ginhka ai lam ni hku nna garan mai ai: shimlam makawp maga ai lam hpe makawp maga ai lam, sumla hkrung hpaw ai lam ni hpe jat bang ai, makawp maga ai positive electrode additives, ngang grin ai lithium sau jat bang ai, lithium hka ntsa na hka lim ai lam hpe n-gun jaw ai, hka hpe shinggyin la lu ai n-gun dat ni hpe jat ya ai, hka n-gun jat ai lam ni, hka lim ai lam hpe jat ya ai jat bang ai lam ni hte kaga ni.
2. electrode arung arai ni a shimlum lam hpe grau kaja hkra galaw na
Lithium iron phosphate hte ternary composites ni hpe wan jak mawdaw hpaga lam hta grai lang mai ai, n law ai- manu n law ai hte "shim lum ai" ngu sawn la ma ai. Cathode materials ni a matu, shanhte a shimlum lam hpe grau kaja hkra galaw na matu, n-gun jaw ai lam gaw, coating hpe galai shai ai lam re. Ga shadawn, n-gun rawng ai arung arai ni hte electrolyte lapran hkrak matut mahkai ai lam hpe pat shingdang lu ai, cathode arung arai ni a phase galai shai ai lam hpe pat shingdang ya lu ai, shanhte a structural stability hpe grau kaja hkra galaw ya lu ai, lattice hta cations ni a n-gun hpe shayawm ya lu ai.
N kaja ai electrode arung arai ni a matu, SEI sumla hkrung a thermal stability hpe gram lajang ai gaw, n kaja ai electrode arung arai ni a shim lum lam hpe grau kaja hkra galaw na matu ahkyak ai ladat rai nga ai, hpa majaw nga yang, shi a ntsa na n-gun gaw, lithium ion battery ni hta, thermochemical decomposition hte exothermic part law dik htum rai nga ai. Anode arung arai ni a thermal stability hpe n-gun kya ai oxidation, metal hte metal oxide n-gun, polymer (sh) carbon coating ni a majaw grau kaja hkra galaw lu ai.
3. Battery shim lum ai hkrang hpe grau kaja hkra galaw ai
Battery arung arai ni a shim lum lam hpe grau kaja hkra galaw ai hta n-ga, sut masa lam hta jai lang ai shimlam makawp maga ai lam law law, battery shim lum ai shara ni, katsi ai{0}}soluble fuse ni, n-gun rawng ai nbung katsi ai lam ni lawm ai series ni, katsi ai{1}}} ni ai diaphragm hpe lang ai, laksan makawp maga ai lam ni hpe gun hpai ai, battery hpe hkang ai ladat ni gaw shim lum lam hpe grau kaja hkra galaw ya lu ai lam ni rai nga ai.
