Intshayelelo:
Iibhetri zeLithiumibe yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, ukunika amandla yonke into ukusuka kwii-smartphones kunye neelaptops ukuya kwizithuthi zombane kunye neenkqubo zokugcina amandla. Iibhetri zeLithium zisetyenziswa ngokubanzi, kodwa kukho iimeko zomlilo kunye nokuqhuma, okuthe, nangona kunqabile, kubangele ukukhathazeka malunga nokhuseleko lwabo. Ukuqonda izinto ezinokukhokelela kwiziganeko ezinjalo kubalulekile ekuqinisekiseni ukusetyenziswa okukhuselekileyo nokuthembekileyo kweebhetri ze-lithium.
Ukuqhuma kwebhetri yeLithium ngumba onzima wokhuseleko, kwaye izizathu zokwenzeka kwazo ziyinkimbinkimbi kwaye ziyahlukahluka, ngokukodwa kubandakanywa izinto zangaphakathi nangaphandle.
Imiba yangaphakathi
Isiphaluka esifutshane sangaphakathi
Ukungonelanga kwe-electrode engafanelekanga amandla: Xa umthamo ongalunganga we-electrode ye-electrode elungileyo yebhetri ye-lithium ungonelanga, ii-athomu ze-lithium ezenziwe ngexesha lokutshaja azikwazi ukufakwa kwisakhiwo se-interlayer yegraphite ye-electrode engalunganga, kwaye iya kudlula kumphezulu we-electrode engalunganga. ukwenza iikristale. Ukuqokelela kwexesha elide kwezi kristale kunokubangela isiphaluka esifutshane, iseli yebhetri ikhupha ngokukhawuleza, ivelise ubushushu obuninzi, itshise i-diaphragm, emva koko ibangele ukuqhuma.
Ukufunxwa kwamanzi e-Electrode kunye nokuphendula kwe-electrolyte: Emva kokuba i-electrode ithatha amanzi, inokusabela kunye ne-electrolyte ukuvelisa i-air bulges, enokuthi ibangele iisekethe ezimfutshane zangaphakathi.
Iingxaki ze-Electrolyte: Umgangatho kunye nokusebenza kwe-electrolyte ngokwayo, kunye nobungakanani bolwelo olutofwayo ngexesha lokutofa olungahambelani neemfuno zenkqubo, kunokuchaphazela ukhuseleko lwebhetri.
Ukungcola kwinkqubo yokuvelisa: Ukungcola, uthuli, njl.
Ukubaleka kwe-thermal
Xa i-thermal ibaleka ngaphakathi kwebhetri ye-lithium, ukusabela kweekhemikhali exothermic kuya kwenzeka phakathi kwezinto zangaphakathi zebhetri, kunye neegesi ezinokutsha ezifana ne-hydrogen, i-carbon monoxide kunye ne-methane ziya kuveliswa. Ezi mpendulo ziya kukhokelela ekuphenduleni okutsha kwecala, ukwenza umjikelo okhohlakeleyo, obangela ubushushu kunye noxinzelelo ngaphakathi kwebhetri ukuba lunyuke ngokukhawuleza, kwaye ekugqibeleni lukhokelela ekuqhumeni.
Ukutshaja ixesha elide kwiseli yebhetri
Ngaphantsi kweemeko zokutshaja kwexesha elide, ukutshaja okugqithisileyo kunye nokugqithiswa kwe-overcurrent nako kunokukhokelela kubushushu obuphezulu kunye noxinzelelo oluphezulu, nto leyo enokubangela iingozi zokhuseleko.
Imiba yangaphandle
Isiphaluka esifutshane sangaphandle
Nangona iisekethe ezimfutshane zangaphandle azifane zibangele ngokuthe ngqo ukubaleka kwebhetri, iisekethe ezimfutshane zangaphandle zexesha elide zinokubangela ukuba iindawo zoqhagamshelo ezibuthathaka kwisekethe zitshise, nto leyo enokubangela iingxaki ezingakumbi zokhuseleko.
Ubushushu obuphezulu bangaphandle
Ngaphantsi kweendawo zokushisa eziphezulu, i-electrolyte solvent yeebhetri ze-lithium iphuma ngokukhawuleza, izinto ze-electrode zanda, kwaye ukunyuka kwangaphakathi kwanda, okunokubangela ukuvuza, iisekethe ezimfutshane, njl., ezibangela ukuqhuma okanye umlilo.
Ukungcangcazela komatshini okanye umonakalo
Xa iibhetri ze-lithium ziphantsi kwe-vibration enamandla okanye umonakalo ngexesha lokuthutha, ukusetyenziswa okanye ukugcinwa, i-diaphragm okanye i-electrolyte yebhetri inokonakala, okukhokelela ekudibaneni ngokuthe ngqo phakathi kwe-lithium yensimbi kunye ne-electrolyte, kubangela ukusabela kwe-exothermic, kwaye ekugqibeleni kukhokelela ekuqhumeni okanye umlilo.
Ingxaki yokutshaja
I-Overcharge: I-circuit yokukhusela ingaphandle kolawulo okanye ikhabhinethi yokubona iphelelwe kulawulo, ibangela ukuba i-voltage yokutshaja ibe mkhulu kune-voltage elinganisiweyo yebhetri, okubangele ukubola kwe-electrolyte, ukuphendula ngobundlobongela ngaphakathi kwebhetri, kunye nokunyuka ngokukhawuleza ngaphakathi. uxinzelelo lwebhetri, olunokubangela ukuqhuma.
I-Overcurrent: Ukutshaja ngokugqithisileyo kunokubangela ukuba i-ion ze-lithium zingabinalo ixesha lokungena kwiqhekeza lepali, kwaye isinyithi se-lithium senziwe kumphezulu weqhekeza lepali, singena kwi-diaphragm, sibangela isiphaluka esifutshane ngokuthe ngqo phakathi kweepali ezilungileyo kunye nezibi kunye nokuqhuma. .
Ukuqukumbela
Izizathu zokuqhuma kwebhetri ye-lithium zibandakanya imijikelezo emfutshane yangaphakathi, i-thermal runaway, i-overcharging yexesha elide ye-cell cell, i-short circuits yangaphandle, ukushisa okuphezulu kwangaphandle, ukungcangcazela komatshini okanye umonakalo, iingxaki zokutshaja, kunye nezinye iinkalo. Ngoko ke, xa usebenzisa kwaye ugcina iibhetri ze-lithium, kuyimfuneko ukuthobela ngokungqongqo imimiselo yokhuseleko olufanelekileyo ukuqinisekisa ukhuseleko kunye nokuzinza kwebhetri. Kwangaxeshanye, ukomeleza ukongamela ukhuseleko kunye namanyathelo okuthintela zikwayindlela ebalulekileyo yokuthintela ukuqhuma kwebhetri ye-lithium.
