UPhando kwiThermal Runaway Ukwandiswa kweLithium Ion yebhetri ukusuka kwiYunithi enye ukuya kwiModyuli

Ngenxa yobuninzi bamandla ebhetri ye-lithium-ion, ukuzinza okuphantsi kwe-thermal yezinto ezilungileyo kunye nezingalunganga, kunye ne-electrolyte evuthayo ye-organic electrolyte, iibhetri ze-lithium-ion zinokuba neengxaki ezinzulu zokhuseleko phantsi kweemeko ezithile, ezifana nokushisa okuphezulu okanye yavutha kwaye yaqhuma.Kukho izizathu ezininzi zeengxaki zokhuseleko lweebhetri ze-lithium-ion, ezifana nomonakalo womatshini, umonakalo wokusingqongileyo, umonakalo wombane, kunye nokungazinzi kwabo.Kungakhathaliseki ukuba yintoni imbangela yeengxaki zokhuseleko lweebhetri ze-lithium-ion, iingozi zokhuseleko ezibonisa iibhetri ze-lithium-ion ekugqibeleni zihamba kunye neesekethe ezimfutshane zangaphakathi nangaphandle ezikhokelela ekunyukeni ngokukhawuleza kweqondo lokushisa okanye umlilo kunye nokuqhuma, oko kukuthi, ingxaki yokubaleka kwe-thermal yeebhetri ze-lithium-ion.

Ngokusetyenziswa okukhulu kweebhetri ze-lithium-ion kwintsimi yezithuthi zombane kunyeukugcinwa kwamandla, iimodyuli zebhetri ezisetyenziselwa izithuthi zombane zidla ngokuba zikhulu kakhulu.Ukuba ubushushu abunakukhutshelwa ngaphandle kwemodyuli yebhetri ngexesha ngenxa yezizathu zoyilo okanye ukusilela kwenkqubo yokupholisa, iseli enye okanye ezininzi ngaphakathi kwimodyuli ziyakwenza uqokelelo lobushushu.Ukuba iqondo lobushushu bebhetri ekugqibeleni lifikelela kwiqondo lobushushu bobushushu bobushushu, ibhetri inokuvuza okanye itshise, okanye ide ibangele ukuba ibhetri igqabhuke.Isiganeko esikhulu esibalekayo senkqubo yonke yebhetri ebangelwa yi-thermal runaway yeebhetri ze-lithium-ion kukwandiswa kwe-thermal runaway yeebhetri ze-lithium-ion.Ngomthamo omkhulu, iimodyuli zebhetri ze-lithium-ion eziphezulu zamandla amakhulu, imiba yokhuseleko ibonakala ngakumbi.Ngenxa yokuba ukwandiswa kwe-thermal ebalekayo kwenzeka kwiimodyuli ezinkulu ze-lithium-ion zebhetri, kunzima kakhulu ukucima umlilo, odla ngokubangela ukulimala kunye nokulahlekelwa okukhulu kwezoqoqosho, kwaye impembelelo inkulu kakhulu.

Ngokutsho iziphumo zovavanyo, umthamo ubushushu ethile yeternary lithium ion ibhetrikunye ne-lithium iron phosphate lithium ion ibhetri esetyenzisiweyo iyafana.Kuvavanyo olwandisiweyo lwe-thermal runaway, emva kokuba imodyuli ye-ternary lithium-ion ibhetri ibangele ukubaleka kwe-thermal yebhetri enye, iibhetri eziseleyo zifumana i-thermal runaway, kwaye zibonise ukuqhelana okuthile ekuphuhlisweni kwe-thermal runaway;I-lithium iron phosphate Ukwandiswa kokubaleka kwe-thermal yemodyuli yebhetri ye-ion akuphumelelanga.Emva kokuqalisa ukubaleka kwebhetri enye, iibhetri ezishiyekileyo azizange zibe nakho ukubaleka kwe-thermal.Emva kweeyure ezi-3 zokufudumeza okuqhubekayo, ukubaleka kwe-thermal akuzange kwenzeke.Ibhetri ye-lithium ion ye-ternary ibamba umlilo kwaye ivutha ngamandla xa ubushushu bungalawuleki, kwaye amandla akhutshwayo aphezulu kunebhetri ye-lithium iron phosphate lithium ion.
