Masiqale siqonde izizathu zokuqhuma kwebhetri:
1. Ukugqithisa okubangelwa ukutshaja ngokugqithiseleyo kuya kubangela ukuba zonke ii-athomu ze-lithium kwizinto eziphathekayo ze-electrode ziqhube kwizinto eziphathekayo ze-electrode, ezibangela ukuba igridi egcweleyo ye-electrode eyiyo igqwese kwaye iwele, ekwangamandla epakethe yebhetri ye-lithium.esona sizathu siphambili sokuhla.Kule nkqubo, ngakumbi nangakumbi i-lithium ion kwi-electrode engalunganga iqokelelwa, kwaye ukuqokelelana okugqithisileyo kubangela ukuba ii-athomu ze-lithium zikhule iziphunzi kunye nekristali, ebangela ukuba ibhetri idumbe.
2. Ifilimu ye-SEI ye-bulging ebangelwa ukukhutshwa ngokugqithiseleyo iya kuba nefuthe elikhuselayo kwizinto eziphathekayo ze-electrode, ukwenzela ukuba isakhiwo sezinto eziphathekayo singabi lula, kwaye ubomi bomjikelezo wezinto ze-electrode bunganyuswa.Ifilimu ye-SEI ayigxili, kwaye kuya kubakho utshintsho oluncinci ngexesha lokutshaja kunye nenkqubo yokukhupha, ngokukodwa ngenxa yokuba ezinye izinto eziphilayo ziya kutshintsha utshintsho.Emva kokuba ibhetri ikhutshwe ngokugqithiseleyo, ifilimu ye-SEI iyaphulwa ngokuphindaphindiweyo, kwaye i-SEI ekhusela izinto ze-electrode engalunganga iyatshatyalaliswa, ibangele ukuba izinto ezingalunganga ze-electrode ziwa, ngaloo ndlela zenze i-bulging phenomenon yebhethri ye-lithium.Ukuba ishaja esetyenzisiweyo ayifuni. Ukuhlangabezana neemfuno, ibhetri iya kugqabhuka ekukhanyeni, kwaye kunokubakho ingozi yokhuseleko okanye ugqabhuko-dubulo.
3. Iingxaki zenkqubo yokwenziwa kwemveliso:
Inqanaba lokwenziwa kweepakethi zebhetri ye-lithium alilingani, i-electrode coating ayilingani, kwaye inkqubo yokuvelisa inzima.Ngokubanzi, iilaptops ziplagiwe ngexesha lokusetyenziswa, kwaye unikezelo lwamandla luqhagamshelwe kakhulu ngalo lonke ixesha.Kukwayinto eqhelekileyo ukuba neqhuma kwixesha elide.
Ukujongana njani nebhulukhwe yebhetri ye-lithium:
1. Qala ukuzalisa amandla emva kokuba isiqingatha samandla sisetyenzisiwe, kwaye wenze kuphela ukukhutshwa okupheleleyo kunye nokugcinwa kwentlawulo epheleleyo kwiimeko ezinqabileyo (umzekelo, emva kweenyanga ezimbalwa ukuya kwisiqingatha sonyaka, iya kukhutshwa ngokupheleleyo kwaye ihlawuliswe kanye. , rhoqo Kulula ukukhulisa iikristali xa utshaja kwaye ukhupha), onokunciphisa kakhulu inani leekristale kunye nokunciphisa kakhulu i-bulging phenomenon.
2. Ibhetri ye-lithium ekhuphayo inokulahlwa ngokuthe ngqo, kuba amandla ombane sele encinci kakhulu, kwaye akukho mandla kuwo onke emva kwesiphaluka esifutshane.
3. Iipakethi zebhetri ye-lithium ngokubanzi kufuneka zihlaziywe ngobungcali ukuze zingabangeli ungcoliseko.Ukuba akukho ndlela yokujongana nazo, kufuneka ziphoswe kwimigqomo ehlaziyiweyo yokurisayikilisha kwindawo yenkonzo yomnikezeli wenkonzo yonxibelelwano ngomnxeba.
