Yini engenzeka uma ibhethri ye-lithium iqhubeka ukushisa?,
Amabhethri,

▍Kuyini i-ANATEL Homologation?

I-ANATEL isho ukuthi i-Agencia Nacional de Telecomunicacoes okuyigunya likahulumeni wase-Brazil ukuze inikeze imikhiqizo yokuxhumana enesitifiketi kukho kokubili izitifiketi eziyimpoqo nezokuzithandela.Izinqubo zokugunyaza nokuhambisana nazo ziyefana emikhiqizweni yasekhaya neyaphesheya yaseBrazil.Uma imikhiqizo isebenza esitifiketini esiyimpoqo, umphumela wokuhlolwa nombiko kufanele kuhambisane nemithetho nemithethonqubo eshiwo njengoba icelwe yi-ANATEL.Isitifiketi somkhiqizo sizonikezwa yi-ANATEL kuqala ngaphambi kokuba umkhiqizo usakazwe ekukhangiseni futhi ufakwe ekusebenzeni okungokoqobo.

▍Ubani onesibopho se-ANATEL Homologation?

Izinhlangano ezijwayelekile zikahulumeni wase-Brazil, ezinye izinhlangano eziqashelwa izitifiketi namalebhu okuhlola ziyiziphathimandla zesitifiketi ze-ANATEL zokuhlaziya uhlelo lokukhiqiza lweyunithi yokukhiqiza, njengenqubo yokuklama umkhiqizo, ukuthengwa kwempahla, inqubo yokukhiqiza, ngemva kwesevisi nokunye ukuze kuqinisekiswe umkhiqizo ongokoqobo okufanele uthotshelwe. ngezinga laseBrazil.Umkhiqizi uzohlinzeka ngamadokhumenti namasampula ukuze ahlolwe futhi ahlolwe.

▍Kungani i-MCM?

● I-MCM inesipiliyoni seminyaka eyi-10 nezinsiza eziningi embonini yokuhlola nezitifiketi: isistimu yesevisi yekhwalithi ephezulu, ithimba lezobuchwepheshe eliqeqeshwe ngokujulile, izitifiketi ezisheshayo nezilula nezisombululo zokuhlola.

● I-MCM isebenzisana nezinhlangano eziningi zendawo eziqashelwa ngokusemthethweni zekhwalithi ephezulu ezinikeza izixazululo ezihlukahlukene, isevisi enembile nefanele amaklayenti.

Eminyakeni yamuva nje, imibiko yomlilo ngisho nokuqhuma okubangelwa amabhethri e-lithium-ion kuvamile.
Amabhethri e-lithium-ion ikakhulukazi akhiwe ngezinto ezingezinhle ze-electrode, i-electrolyte kanye nezinto ezibonakalayo ze-electrode.Umsebenzi wamakhemikhali we-graphite ye-electrode engalungile esimweni esikhokhisiwe ufana ne-lithium yensimbi.Ifilimu ye-SEI engaphezulu ingabola ekushiseni okuphezulu, futhi ama-ion e-lithium ashumekwe ku-graphite azosabela nge-electrolyte kanye ne-binder polyvinylidene fluoride futhi ekugcineni azokhipha ukushisa okuningi.
I-Alkyl carbonate organic solutions ivame ukusetshenziswa njengama-electrolyte, avutha umlilo.Okuhle
I-electrode material ngokuvamile i-transition metal oxide, enezindawo eziqinile ze-oxidizing esimweni sokushajwa, futhi ibola kalula ukuze ikhulule umoya-mpilo ezingeni lokushisa eliphezulu.I-oxygen ekhishiwe isabela ne-electrolyte ukuze i-oxidize, bese iphuma ukushisa okuningi.
Ngokufanelekile, ibhethri ye-lithium ion ibingeke izinze uma ishisisa ngezinga lokushisa eliphezulu.Nokho, yini
kuzokwenzekani uma siqhubeka sishisisa ibhethri?Lapha senze ukuhlola kwangempela kuseli ye-NCM egcwele amandla kagesi engu-3.7 V kanye nomthamo ongu-106 Ah.
Izindlela Zokuhlola:
1. Emazingeni okushisa asekamelweni (25±2℃), ingqamuzana elilodwa liqale likhishelwe ku-voltage yomkhawulo ophansi nge-current.
1C bese ushiya imizuzu engu-15.Bese usebenzisa i-1C engaguquki yamanje ukushaja ku-voltage yomkhawulo ophezulu bese ushintsha
ekushajweni kwamandla kagesi njalo, yeka ukushaja lapho amandla okushaja ehla aze afike ku-0.05C, bese uwabeka eceleni
Imizuzu engu-15 ngemva kokushaja;
