18650 ibhethri ye-lithium-ion ukushaja emazingeni okushisa aphansi kuzoba nomthelela onjani?Ake siyibheke ngezansi.
Uyini umphumela wokushaja ibhethri ye-lithium-ion engu-18650 endaweni yokushisa ephansi?
Ukushaja amabhethri e-lithium-ion endaweni enezinga lokushisa eliphansi kubangela ubungozi obuthile bokuphepha.Lokhu kungenxa yokuthi kanye nokuncishiswa komswakama, izakhiwo ze-kinetic ze-electrode eyi-graphite negative ziqhubekela phambili ukuwohloka kuseshini yokushaja, i-electrochemical polarization ye-electrode negative iba kubi kakhulu, ukuna kwensimbi ye-lithium kuthambekele ekwakhiweni kwe-lithium. ama-dendrites, aphakamisa i-diaphragm futhi ngaleyo ndlela abangele umjikelezo omfushane wama-electrode aqondile noma angalungile.Ukuvimbela ukushajwa kwebhethri ye-lithium-ion ngangokunokwenzeka emazingeni okushisa aphansi.
Uma kucatshangelwa izinga lokushisa eliphansi, i-electrode engalungile ebhethri ye-lithium-ion efakwe esidlekeni izovela amakristalu e-ion, ingabhoboza ngokuqondile i-diaphragm, ngaphansi kwezimo ezijwayelekile izobangela i-micro-short circuit ithinta impilo nokusebenza, okuyingozi nakakhulu kungenzeka ukuthi iqhume!
Ngokusho kocwaningo lochwepheshe olugunyaziwe: amabhethri e-lithium-ion isikhathi esifushane endaweni enezinga lokushisa eliphansi, noma izinga lokushisa likude kakhulu, lizothinta okwesikhashana umthamo webhethri lamabhethri e-lithium-ion, kodwa ngeke akhiqize umonakalo unomphela. .Kodwa uma isetshenziswa isikhathi eside endaweni enezinga lokushisa eliphansi, noma ku -40 ℃ endaweni yokushisa ephansi kakhulu, amabhethri e-lithium-ion angase aqandiswe ukuze adale umonakalo unomphela.
Ukusetshenziswa kwezinga lokushisa eliphansi kwamabhethri e-lithium-ion kuhlushwa umthamo ophansi, ukubola okukhulu, ukusebenza kabi kwesiphindaphinda somjikelezo, ukujuluka kwe-lithium okugqame kakhulu, kanye nokushumeka kwe-lithium okungalinganiseli.Kodwa-ke, kanye nokuqamba okusha okuqhubekayo kokusetshenziswa okuyinhloko, izithiyo ezilethwa ukungasebenzi kahle kwezinga lokushisa eliphansi lamabhethri e-lithium-ion ziya ngokuya ziba sobala kakhulu.Ezimoyeni ezisindayo, ezimotweni ezisindayo, ezimotweni zikagesi nezinye izinkambu, ibhethri liyadingeka ukuze lisebenze kahle ku -40°C.Ngakho-ke, ukuthuthukiswa okuqhubekayo kwezinto ezisezingeni eliphansi zamabhethri e-lithium-ion kunokubaluleka kwamasu.
Kunjalo,uma ibhethri yakho ye-lithium engu-18650 ifakwe izinto ezisezingeni lokushisa eliphansi, isengashajwa ngokujwayelekile endaweni enezinga lokushisa eliphansi.
