Mumakore achangopfuura, mishumo yemoto uye kunyange kuputika kunokonzerwa nemabhatiri e-lithium-ion kwakajairika.Mabhatiri eLithium-ion anonyanya kuumbwa nezvinhu zvisina kunaka zve electrode, electrolyte uye zvakanaka electrode material. Kuitwa kwemakemikari kweiyo negative electrode material graphite mu charged state inenge yakaita sesimbi lithium. Iyo SEI firimu iri pamusoro yaizoora pakupisa kukuru, uye maion lithium akaiswa mugirafu aizoita ne electrolyte uye binder polyvinylidene fluoride uye pakupedzisira aizobudisa kupisa kwakawanda.
Alkyl carbonate organic solutions inowanzoshandiswa se electrolytes, iyo inogona kupisa. Iyo yakanaka electrode zvinhu zvinowanzova shanduko yesimbi oxide, ine yakasimba oxidizing zvimiro muchaji mamiriro, uye inoora nyore kuburitsa okisijeni pakupisa kwakanyanya. Okisijeni yakaburitswa inopindirana ne electrolyte kuti iite oxidize, yobva yabuda kupisa kwakawanda.
Apperately, iyo lithium ion bhatiri yaizove isina kugadzikana kana ichidziya nekushisa kwakanyanya. Zvisinei, chii chaizvo chingaitika kana tikaramba tichidziyisa bhatiri? Pano takaita bvunzo chaiyo kune yakazara chaji NCM cell ine voltage ye3.7 V uye huwandu hwe106 Ah.
Kuedza Nzira:
1. Patembiricha yekamuri (25 ± 2 ℃), sero rimwe chete rinotanga kuburitswa kune yakaderera muganhu voltage ine ikozvino ye1C uye yasara kwemaminitsi gumi nemashanu. Wobva washandisa 1C inogara iripo kubhadharisa kune yekumusoro muganhu voltage uye chinja kune inogara ichichaja voltage, rega kuchaja kana iyo yekuchaja inodonha kusvika 0.05C, uye isa parutivi kwemaminitsi gumi nemashanu mushure mekuchaja;
2. Wedzera tembiricha kubva mukamuri tembiricha kusvika 200 ° C pa5 ° C / min, uye chengeta pa5 ° C parita kwemaminitsi makumi matatu;
Mhedziso:
Lithium maseru anozopedzisira abata moto kana tembiricha yekuyedza ikaramba ichiwedzera. Kubva pamaitiro ari pamusoro tinotanga kuona vharuvhu yekuburitsa yakavhurwa, iyo mvura yakadzimwa; sezvo tembiricha ichikwira mberi, ejection yechipiri yemvura yakaitika uye inotanga kupisa. Masero ebhatiri akatadza kutenderera 138°C, yaive yatokwira kudarika tembiricha yakajairwa ye130°C.
