Kafukufuku pa Thermal Runaway Kukula kwa Battery ya Lithium Ion kuchokera ku Chigawo Chimodzi kupita ku Module

Chifukwa cha kuchuluka kwa mphamvu zamabatire a lithiamu-ion, kukhazikika kwamafuta otsika azinthu zabwino ndi zoyipa, komanso ma electrolyte oyaka organic electrolyte, mabatire a lithiamu-ion amatha kukhala ndi zovuta zazikulu zachitetezo pamikhalidwe ina, monga kutentha kwambiri kapena ngakhale idayaka moto ndikuphulika.Pali zifukwa zambiri za mavuto a chitetezo cha mabatire a lithiamu-ion, monga kuwonongeka kwa makina, kuwonongeka kwa chilengedwe, kuwonongeka kwa magetsi, ndi kusakhazikika kwawo.Mosasamala kanthu zomwe zimayambitsa zovuta zachitetezo cha mabatire a lithiamu-ion, ngozi zachitetezo zomwe mabatire a lithiamu-ion pamapeto pake amawonetsa zimatsagana ndi mafupipafupi amkati ndi akunja omwe amatsogolera kukukwera kwakukulu kwa kutentha kapena ngakhale moto ndi kuphulika, ndiko kuti, vuto la kutha kwa matenthedwe a mabatire a lithiamu-ion.

Ndi kugwiritsa ntchito kwakukulu kwa mabatire a lithiamu-ion pamagalimoto amagetsi ndikusungirako mphamvu, ma modules a batri omwe amagwiritsidwa ntchito mu magalimoto amagetsi nthawi zambiri amakhala aakulu kwambiri.Ngati kutentha sikungathe kutulutsidwa kunja kwa gawo la batri mu nthawi chifukwa cha zifukwa za mapangidwe kapena kulephera kwa dongosolo lozizira, selo limodzi kapena angapo mkati mwa gawolo lidzapanga kudzikundikira kutentha.Ngati kutentha kwa batire kumafika pakutha kwa kutentha, batire imatha kutsika kapena kuyaka, kapenanso kupangitsa kuti batire liphulike.Chochitika chachikulu cha kuthawa kwa dongosolo lonse la batri chifukwa cha kuthawa kwamphamvu kwa mabatire a lithiamu-ion ndi kufalikira kwa kutentha kwa mabatire a lithiamu-ion.Kwa mphamvu zazikulu, ma module a batri a lithiamu-ion amphamvu kwambiri, zovuta zachitetezo ndizodziwika kwambiri.Chifukwa kuwonjezereka kwa kutentha kwa kutentha kumapezeka pa ma modules akuluakulu a lithiamu-ion batri, zimakhala zovuta kuzimitsa moto, zomwe nthawi zambiri zimayambitsa kuvulala ndi kuwonongeka kwakukulu kwachuma, ndipo zotsatira zake zimakhala zazikulu kwambiri.

Malinga ndi zotsatira mayeso, yeniyeni kutentha mphamvu yaternary lithiamu ion batrindi lithiamu iron phosphate lithiamu ion batire yogwiritsidwa ntchito ndizofanana.Mu matenthedwe kuthawa anawonjezera mayeso, pambuyo ternary lithiamu-ion batire gawo linayambitsa kutha kwa matenthedwe a batire imodzi, mabatire otsala anakumana matenthedwe kuthawira nayenso, ndipo anasonyeza nthawi zonse mu chitukuko cha matenthedwe kuthawa;Lifiyamu iron phosphate Kuwonjezeredwa kwamphamvu kwa batire ya ion moduli sikunachitike.Pambuyo poyambitsa kutha kwa batire limodzi, mabatire otsalawo sanakumane ndi kutha kwa matenthedwe.Pambuyo pa maola atatu akutentha kosalekeza, kuthawa kwa kutentha sikunachitike.Battery ya ternary lithiamu ion imagwira moto ndikuwotcha mwamphamvu pamene kutentha sikutha kulamulira, ndipo mphamvu yotulutsidwa ndipamwamba kuposa ya lithiamu iron phosphate lithiamu ion batri.
