Intshayelelo:
Iibhetri zeLithiumziye zaba yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, zinika amandla yonke into ukusuka kwiifowuni eziphathwayo kunye neelaptops ukuya kwizithuthi zombane kunye neenkqubo zokugcina amandla. Iibhetri zeLithium zisetyenziswa kakhulu, kodwa kuye kwakho iimeko zemililo kunye nokuqhuma, nangona zinqabile, eziye zaphakamisa inkxalabo malunga nokhuseleko lwazo. Ukuqonda izinto ezinokubangela ezo ziganeko kubalulekile ukuqinisekisa ukusetyenziswa ngokukhuselekileyo nangokuthembekileyo kweebhetri zeLithium.
Ukuqhuma kwebhetri yeLithium yingxaki enkulu yokhuseleko, kwaye izizathu zokwenzeka kwazo ziyinkimbinkimbi kwaye zahlukile, ikakhulu kubandakanya izinto zangaphakathi nezangaphandle.
Izinto zangaphakathi
Isekethe emfutshane yangaphakathi
Umthamo we-electrode engalunganga owaneleyo: Xa umthamo we-electrode engalunganga we-electrode echanekileyo yebhetri ye-lithium unganelanga, ii-athomu ze-lithium ezenziwe ngexesha lokutshaja azinakufakwa kwisakhiwo se-interlayer ye-graphite engalunganga ye-electrode, kwaye ziya kuwela phezu komphezulu we-electrode engalunganga ukuze zenze iikristale. Ukuqokelelana kwexesha elide kwezi kristale kunokubangela i-short circuit, iseli yebhetri ikhupha ngokukhawuleza, ivelise ubushushu obuninzi, itshise i-diaphragm, ize emva koko ibangele ukuqhuma.
Ukufunxwa kwamanzi yi-electrode kunye nokusabela kwe-electrolyte: Emva kokuba i-electrode ifunxwa ngamanzi, inokusabela kunye ne-electrolyte ukuvelisa amaqhubu omoya, nto leyo enokubangela ukuba kubekho imijikelo emfutshane yangaphakathi.
Iingxaki ze-Electrolyte: Umgangatho kunye nokusebenza kwe-electrolyte ngokwayo, kunye nobungakanani bolwelo olufakwayo ngexesha lokujova olungahlangabezani neemfuno zenkqubo, zinokuchaphazela ukhuseleko lwebhetri.
Ukungcola kwinkqubo yokuvelisa: Ukungcola, uthuli, njl.njl. okunokubakho ngexesha lenkqubo yokuvelisa ibhetri nako kunokubangela iisekethe ezincinci.
Ukubaleka kobushushu
Xa kwenzeka i-thermal runaway ngaphakathi kwebhetri ye-lithium, kuya kwenzeka i-exothermic chemical reaction phakathi kwezinto zangaphakathi zebhetri, kwaye kuya kuveliswa iigesi ezivuthayo ezifana ne-hydrogen, i-carbon monoxide, kunye ne-methane. Ezi mpendulo ziya kukhokelela kwiimpendulo ezintsha ezingasemva, zenze umjikelo ombi, obangela ukuba ubushushu kunye noxinzelelo ngaphakathi kwebhetri lunyuke kakhulu, kwaye ekugqibeleni lukhokelele ekuqhumeni.
Ukutshaja kakhulu ixesha elide kweseli yebhetri
Phantsi kweemeko zokutshaja ixesha elide, ukutshaja kakhulu kunye nokugqithisa kombane kunokukhokelela kubushushu obuphezulu kunye noxinzelelo oluphezulu, nto leyo enokubangela iingozi zokhuseleko.
Izinto zangaphandle
Isekethe emfutshane yangaphandle
Nangona iisekethe ezimfutshane zangaphandle zingasoloko zibangela ukuba ibhetri ingasebenzi kakuhle, iisekethe ezimfutshane zangaphandle zexesha elide zinokubangela ukuba iindawo zonxibelelwano ezibuthathaka kwisekethe zitshise, nto leyo enokubangela iingxaki ezinkulu zokhuseleko.
Ubushushu obuphezulu bangaphandle
Phantsi kweemeko zobushushu obuphezulu, i-electrolyte solvent yeebhetri ze-lithium iyaphela ngokukhawuleza, izinto ze-electrode ziyanda, kwaye ukumelana kwangaphakathi kuyanda, okunokubangela ukuvuza, ii-short circuits, njl.njl., okubangela ukuqhuma okanye imililo.
Ukungcangcazela okanye umonakalo woomatshini
Xa iibhetri ze-lithium ziphantsi kokungcangcazela okanye umonakalo omkhulu woomatshini ngexesha lokuthuthwa, ukusetyenziswa okanye ukulungiswa, i-diaphragm okanye i-electrolyte yebhetri inokonakala, okubangela ukudibana ngqo phakathi kwe-lithium yesinyithi kunye ne-electrolyte, okubangela ukusabela okungaqhelekanga, kwaye ekugqibeleni kukhokelela ekuqhumeni okanye emlilweni.
Ingxaki yokutshaja
Ukutshaja kakhulu: Isekethe yokukhusela ayilawuleki okanye ikhabhinethi yokubona ayilawuleki, nto leyo ebangela ukuba i-voltage yokutshaja ibe nkulu kune-voltage elinganisiweyo yebhetri, nto leyo ebangela ukubola kwe-electrolyte, iimpembelelo ezinamandla ngaphakathi kwebhetri, kunye nokunyuka ngokukhawuleza koxinzelelo lwangaphakathi lwebhetri, nto leyo enokubangela ukuqhuma.
Umbane ogqithisileyo: Umbane otshaja kakhulu unokubangela ukuba ii-ion ze-lithium zingabi naxesha lokungena kwi-pole piece, kwaye i-lithium metal yenziwa phezu komphezulu we-pole piece, ingena kwi-diaphragm, nto leyo ebangela umjikelo omfutshane phakathi kwee-positive kunye ne-negative kunye nokuqhuma.
Isiphelo
Izizathu zokuqhuma kwebhetri ye-lithium ziquka ii-internal short circuits, i-thermal runaway, i-overcharger yexesha elide yeseli yebhetri, ii-external short circuits, amaqondo obushushu aphezulu angaphandle, ukungcangcazela okanye umonakalo woomatshini, iingxaki zokutshaja, kunye nezinye izinto. Ke ngoko, xa usebenzisa kwaye ugcina iibhetri ze-lithium, kuyimfuneko ukulandela ngokungqongqo imigaqo yokhuseleko efanelekileyo ukuqinisekisa ukhuseleko kunye nokuzinza kwebhetri. Kwangaxeshanye, ukomeleza ukubekwa kweliso lokhuseleko kunye namanyathelo okuthintela nazo zizinto ezibalulekileyo zokuthintela ukuqhuma kwebhetri ye-lithium.
