Lithium{-ion a n-gun atsam battery ni gara hku galaw ai kun?
Lai wa sai shata hta anhte gaw "n kaja ai bungli galaw ai lam" ngu ai cell ni a batch langai hpe bai nhtang jaw ai. Anhte a chyam dinglik hpung ni gaw, ana jep chyoi ai lam hpe galaw ai shaloi, cell ni gaw kaja ai-}} gaw, shanhte a system gaw 2C hta 40℃ambient makau grup yin hta matut manoi pru wa ai, dai hpang shanhte gaw 0.5C hte 25℃hta shadawn ai datasheet nambat ni hte mahtai ni hpe shingdaw yu ai. Ndai zawn re ai n htap htuk ai lam gaw, hpaga lam hta shang lawm na hpe ra sharawng ai hta grau nna byin pru wa ai, dai gaw madung lam langai hpe madi madun ai: lithium-ion battery galaw ai lam gaw nambat langai sha n re. Dai gaw, nbung katsi ai, load profile, charge a masa, asak hte galai shai mat ai mahtai ntsa langai mi re.

Grid storage system a matu round{13}}}trip efficiency hpe grau kaja hkra galaw na matu, decimal de du hkra, n re.
Temperature performance gaw anhte a hpaji masa madi shadaw ai aten law malawng hpe jai lang ai shara rai nga ai, grau nna dingdung daw na nbung laru ni hte Sinpraw Dingda Asia mungdan ni a gat lawk ni hta mari ai ni hte rau, dai zawn re ai npu na physics manghkang ni.-20℃hta, LFP cells ni gaw 60% daram lang mai ai atsam de hkrat sum mat ai. NMC gaw 85% daram hta grau kaja ai hpe hkam la lu ai majaw, dai hpe 85% daram mu lu ai majaw, dai hpe 85% daram mu lu ai. Ladat ni hpe atsawm sha chye na ai: electrolyte viscosity law wa ai, SEI layer hpe pat shingdang ai lam ni rawt jat wa ai, charge htawt sit ai lam gaw interface shagu hta shayawm mat wa ai. CATL a Shenxing Pro gaw ndai lam hta tengman ai rawt jat lam hpe madi madun ai -20℃charge galaw ai minit 20 kaw nna 478 km lapran re ngu tsun ai.

Anhte gaw, n-gun ja ai masa hta bung ai pack ni a matu 8-10% daram sum mat ai hot{11}}climate deploy ni hta pack ni hpe hkan tam yu ga ai. Dai n-gun yawm mat ai lam ni: SEI layer gaw n-gun ja wa ai, lithium inventory hpe jai lang ai, pat shingdang ai lam ni hpe shabyin ya ai, cycle jawn ai shaloi katsi ai hpe grau law hkra shabyin ya ai, dai gaw grau nna hkrat sum ai lam hpe grau lawan shangun ai. Middle East kaw na customer langai mi gaw, shanhte a lahkawng ning na garan gachyan ai lam ni law wa ai shaloi, ndai lam hpe yak hkak ai hku sharin la lu ai.
Datasheet ni hta lawm ai cycle prat jahpan ni gaw, 25℃, 1C/1C charge-discharge, 100% sung ai hka pru ai lam hpe hkam la ai. Gara variable hpe raitim galai kau nna nambat ni gaw grai galai shai mat ai. Anhte gaw 50% DOD operation gaw 3-5x daram hpe full depth cycling hte shingdaw yang 3-5x hte jat wa ai hpe customers ni hpe tsun dan ga ai. 100% DOD hte 3,000-5,000 hta 500-1,000 shingjawng ai lam lapran na shai hkat ai lam gaw, madu ai lam a manu yawng a matu grai kaba ai akyu ni nga ai, raitim, dai gaw pack hpe grai law hkra jai lang ra ai, dai gaw upfront manu hte n-gun hpe jat ya ai. Engineering gaw hpaga yumga lam hte seng ai; battery lata ai lam mung dai zawn n re.
Hkamja lam gaw thermal stability de du wa nna, thermal stability gaw chemistry de hkrat wa ai. LFP a olivine structure gaw oxygen atoms ni hpe ngang ngang jum da ai-}thermal decomposition hpe 270℃daram du hkra n hpang ai, NMC a matu 210℃hte shingdaw yang.

Solid-state, silicon anodes, sodium-ion gaw Lab kaw nna pilot galaw ai de rawt jat wa nga ai. Aprius gaw silicon anode 500 hpe madun dan sai. CATL a sodium-ion Naxtra gaw 175 hpe lu la nna, 10,000-cycle prat hte 175 hpe lu la ai. Ndai ni gaw masum ning, manga ning laman gat lawk hpe bai gram lajang ai rai tim, ya aten na{ 12}} generation lithium-ion gaw ndai shaning shi ning laman hta jai lang ai lam law malawng a matu bungli galaw ai gumra langai hku nna naw nga na re.
