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 efanelekileyo yebhetri ye-lithium ayanelanga, ii-athomu ze-lithium ezenziwe ngexesha lokutshaja azikwazi ukufakwa kwisakhiwo se-interlayer ye-graphite ye-electrode engalunganga, kwaye iya kudlula phezu kwendawo ye-electrode engalunganga ukuze yenze i-crystals. 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 ukubaleka kwebhetri ngokuthe ngqo, 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 zixhomekeke kwi-vibration enamandla okanye umonakalo ngexesha lokuthutha, ukusetyenziswa okanye ukugcinwa, i-diaphragm okanye i-electrolyte yebhetri inokonakala, okubangelwa ukudibanisa ngokuthe ngqo phakathi kwe-lithium yensimbi kunye ne-electrolyte, kubangela ukusabela okuphumayo, kwaye ekugqibeleni kukhokelela ekuqhumeni okanye umlilo.
Ingxaki yokutshaja
I-Overcharge: Isekethe yokukhusela ingaphandle kolawulo okanye ikhabhinethi yokubona ingaphandle kolawulo, ibangela ukuba i-voltage yokutshaja ibe mkhulu kunombane olinganisiweyo webhetri, okubangela ukubola kwe-electrolyte, ukusabela okunobundlobongela ngaphakathi kwebhetri, kunye nokunyuka ngokukhawuleza koxinzelelo lwangaphakathi lwebhetri, olunokubangela ukuqhuma.
I-Overcurrent: Ukutshaja ngokugqithisileyo kunokubangela ukuba i-ion ze-lithium zingabi naxesha lokungena kwisiqwenga sepali, kwaye isinyithi se-lithium senziwe kumphezulu wesiqwenga sepali, 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.
