Kaja dik ai lithium-ion battery hte seng nna, capacity balance gaw shi a cycle aten hta n galai shai na re, cycle shagu hta shawng nnan na atsam gaw manu langai ngai rai ra ai. Raitim, teng sha nga yang masa gaw grau sawng ai. Lithium ions ni pru wa chye ai (sh) jai lang mai ai gara maga na reaction nga ai rai yang, battery a n-gun hpe galai shai shangun chye ai. Battery balance galai shai wa ai shaloi, ndai galai shai ai lam gaw n mai gram lajang lu ai hte, cycle law law hpe shinggyin la lu ai majaw, battery a cycle a bungli galaw ai lam hpe grai hkra machyi shangun ai. Kaput ai.
Lithium-ion battery ni a cycle prat hpe hkra machyi shangun ai lam law law nga ai, raitim, npu kaw na npawt nhpang lam gaw, n-gun htawt sit ai lam hta shang lawm ai lithium ions ni a jahpan gaw, ayan na yawm wa nga ai. Battery hta lithium elements yawng n yawm mat ai hpe sadi ra ai, raitim, activated lithium ions ni gaw n law ai hpe sadi ra ai. Shanhte hpe kaga shara ni hta (sh) shamu shamawt ai lam ni hpe pat da ai, charge hte discharge a shingra tara hta wanglu wanglang n mai shang lawm ai.
Dai hpang, ndai redox reaction hta shang lawm na ngu ai ndai lithium ions ni gara de sa wa ai hpe sawk sagawn ai aten du hkra, anhte gaw capacity hkrat sum ai lam hpe sawk sagawn lu ai, anhte gaw, lithium{{0}ion battery ni a atsam yawm wa ai lam hpe jahkring kau na matu, yaw shada ai ladat ni hpe hkan sa mai ai. Lithium-ion battery ni a shingra tara hpe grau kaja hkra galaw u.
1. Metallic lithium hpe jaw ai
Shawng na sawk sagawn ai lam hku nna, lithium a magri hkrang hkrang gaw lithium-ion battery ni hta n nga ging ai hpe anhte chye na ga ai. Lithium element gaw, magri oxides, carbon{2}}lithium n-gun (sh) ions ni a hkrang hku nna nga ai.
Metallic lithium hpe n-gun dat dat ai lam gaw, n-gun n-gun n-rawng ai electrode a ntsa e byin pru wa ai. Hpa majaw nga yang, lithium ions ni gaw negative electrode a ntsa de htawt sit wa ai shaloi, lithium ion nkau mi gaw negative electrode a active material de n shang nna, ngang grin ai n-gun ni hpe byin shangun ai. De a malai, shanhte gaw n-gun n-gun n-gun n-gun n-gun n-gun n-nga mat na matu, n-gun n-rawng ai electrode a ntsa e electron ni hpe lu la nna, n-gup n-gu n-gun n-nga mat ai majaw, hpang na cycle ladat hta n shang lawm mat ai majaw, Capacity yawm mat wa ai.
Ndai masa gaw, madung hku nna, lam law law a majaw byin pru wa ai: charge galaw ai gaw, cut-off voltage hpe lai di ai; manu kaba ai hku charge galaw ai; n law ai n kaja ai electrode arung arai. Grai htum mat ai (sh) n kaja ai electrode n-gun n law ai shaloi, n kaja ai electrode gaw, n-gun n rawng ai electrode kaw na htawt sit ai lithium ions hpe n mai hkap la ai majaw, metallic lithium hpe n-gun n rawng mat ai. Rate law ai hte charge galaw ai shaloi, lithium ions law law gaw aten kadun laman hta negative electrode de du wa ai majaw, n-gun n rawng ai hte n-gun yawm mat ai.
Metallic lithium hpe shayawm kau ai gaw, cycle prat hpe shayawm kau ya ai sha n-ga, grai sawng ai masa ni hta, kaja ai hte n kaja ai electrode ni hpe kadun ai hku hkawm sa shangun nna, shimlam manghkang ni grai sawng wa na re.
Ndai manghkang hpe hparan na matu, kaja ai hte n kaja ai electrode arung arai ni a hkam la mai ai shadawn shadang hpe lu ra ai, dai aten hta sha, jai lang ai shadawn shadang hpe n jan hkra makawp maga na matu, lithium-ion battery ni hpe jai lang ai masa ni hpe grai pat shingdang da ra ai. Teng sha nga yang, rate performance kaw nna hpang nna, cycle prat hpe mung daw mi grau kaja hkra galaw mai ai.
2. Cathode arung arai ni hpe garan ginhka ai lam
Lithium- hta lang ai magri oxide hpe cathode material hku lang ai gaw ngang grin ai lam law law nga ai raitim, galu kaba ai- aten hta matut nna htum mat wa na re, electrochemical inert substance nkau mi (Co3O4, Mn2O3, etc.) hte wan hkru mai ai wan n-gun nkau mi pru wa na re. Electrode lapran na atsam rap ra ai lam hpe jahten kau ya ai majaw, n mai gram lajang lu ai atsam sum mat ai.
Ndai masa gaw grau nna grai law hkra charge galaw ai shaloi dan dawng nga ai, kalang lang n-gun ja ai hku n-gun shayawm ai hte gas shapraw ai lam byin chye ai, dai gaw battery a atsam hpe hkra machyi shangun ai sha n-ga, shimlam grai sawng ai hpe mung shabyin ya ai.
Dai hta n-ga, battery a charge htum-off voltage hpe mung, n-gun dat nna, n-gun n-gun hpe shayawm ya ai, cathode material a chemical stability hte thermal stability hpe mung jat ya ai gaw, cycle prat yawm wa ai hpe shayawm na matu, mai byin ai ladat langai mung rai nga ai.
