Yintoni indlela yokubaleka kwe-thermal yeebhetri zamandla?
Ingqikelelo yokubaleka kwebhetri eshushu kunye nokhuseleko lobushushu
Ibhetri ye-thermal runaway ibhekiselele kwintshukumo enobundlobongela ebhetrini, ebangelwa ziimeko ezithile zangaphandle (ezifana nokugqobhoza, ukufudumeza, isiphaluka esifutshane, ukutshaja kakhulu, njl.njl.), ephawulwa ngokukakhulu ngokukhutshwa kobushushu okukhawulezayo nobukhulu, kwaye okunokubakho kukhatshwa lolunye utshintsho lomzimba okanye lwekhemikhali (olufana{1}} nokukhutshwa kwesekethe, ukutsha, njl njl.
Kwinkqubo yebhetri yamandla, xa iseli enye ifumana i-thermal ebalekayo, intshukumo yayo enobundlobongela ivelisa umthamo omkhulu wobushushu kwaye inokuvelisa iziphumo ezinobundlobongela ezinje ngokutsha okanye ugqabhuko-dubulo. Iziphumo zobushushu obuphezulu okanye ukothuka koomatshini kudla ngokubakhoiimeko ezibangela ukubaleka kwe-thermalkwizisele ezingabamelwane. Le nkqubo inokusasazeka ngokulula ukusuka kwiseli enye kuyo yonke inkqubo yebhetri, ibangele ukukhutshwa ngokukhawuleza kwamandla amakhulu, kunye neengozi eziphezulu kakhulu. Imiba yokhuseleko lobushushu bebhetri phantsi kweemeko zokwenyani zokusetyenziswa ibonakaliswa ziindlela ezintsonkothileyo kunye nezinto ezininzi ezinefuthe, ikakhulu ezibonakaliswa kule miba ilandelayo:
I-1) Ukhuseleko lwe-thermal yeseli enye yebhetri yamandla ihambelana ngokuthe ngqo nohlobo lwangaphakathi lwenkqubo ye-electrochemical, ukubunjwa kwezinto eziphathekayo, ifom yesakhiwo, ifom yokupakisha, umthamo, isakhiwo, imilo, ubungakanani kunye nenkqubo yokuvelisa.
2) Ukuqwalasela iimeko ezibangela ukubaleka kwebhetri eshushu, ukufudumala, ukutshaja, iimpembelelo zangaphandle, ukunyanzeliswa, i-punctures, kunye neesekethe ezimfutshane zinokubangela ukubaleka kwe-thermal.
I-3) Ngokumalunga nokusasazwa kwe-thermal runaway kwinkqubo yebhetri, iimeko zokusingqongileyo, indlela yokuqalisa kunye nelizwe lokulayisha, indlela yokudibanisa ibhetri, indlela yokulawula i-thermal, kunye nendawo yebhetri eqala ukubaleka kwe-thermal ngaphakathi kwenkqubo yebhetri yamandla ichaphazela ngokuthe ngqo inkqubo yokusabalalisa i-thermal.
Ngenxa yezi mpawu, ulawulo lokhuseleko lwe-thermal ebhetri lubaluleke kakhulu, ngakumbi ekuphuculeni ukhuseleko olupheleleyo lwezithuthi zombane. Uyilo lwenkqubo yolawulo lokhuseleko lobushushu bebhetri ngokubanzi lujolise ekunikeni isilumkiso kwangethuba phambi kokubaleka kwe-thermal, ukulibazisa ukusasazeka kunye nokusasazwa kwayo ngexesha lokubaleka kwe-thermal, kunye nokunciphisa ilahleko emva kokubaleka kwe-thermal. Oku kubandakanya ukuphuhlisa ukhuselo lokhuseleko kunye nezicwangciso zokulawula, kunye nokuyila{2}}izixhobo zebhetri ezikhuselekileyo zamandla, izakhiwo zangaphakathi, iindlela zokupakisha, kunye nezakhiwo zebhokisi yebhetri ukukhangela ngokukhawuleza iingozi ezinokuthi zibaleke kwaye zithintele ngokufanelekileyo okanye zilibazise ukusasazwa kwayo.
