Kuya kwenzeka ntoni ukuba ngokuqhubekayo ukufudumala ibhetri ye-lithium ?,
Iibhetri,

▍Yintoni i-ANATEL Homologation?

I-ANATEL yinto emfutshane ye-Agencia Nacional de Telecomunicacoes enegunya likarhulumente waseBrazil kwiimveliso zonxibelelwano eziqinisekisiweyo kuzo zombini isiqinisekiso esisisinyanzelo kunye nesokuzithandela. Ukuvunywa kwayo kunye neenkqubo zokuthotyelwa ziyafana zombini kwimveliso yaseBrazil yasekhaya nakwamanye amazwe. Ukuba iimveliso zisebenza kwisatifikethi esinyanzelekileyo, isiphumo sovavanyo kunye nengxelo kufuneka ihambelane nemigaqo nemimiselo echaziweyo njengoko kucelwe ngu-ANATEL. Isiqinisekiso semveliso siya kunikwa ngu ANATEL kuqala phambi kokuba imveliso isasazwe kwintengiso kwaye ifakwe kwisicelo esisebenzayo.

▍ Ngubani onoxanduva lwe-ANATEL Homologation?

Imibutho esemgangathweni karhulumente waseBrazil, amanye amaqumrhu esiqinisekiso kunye neelebhu zovavanyo zinegunya lesiqinisekiso se-ANATEL sokuhlalutya inkqubo yemveliso yeyunithi yokuvelisa, njengenkqubo yoyilo lwemveliso, ukuthengwa kwempahla, inkqubo yokuvelisa, emva kwenkonzo njalo njalo ukuqinisekisa imveliso ebonakalayo ukuba ithotyelwe. ngomgangatho waseBrazil. Umenzi uya kubonelela ngamaxwebhu kunye neesampuli zovavanyo kunye novavanyo.

▍Kutheni i-MCM?

● I-MCM ineminyaka eyi-10 yamava amaninzi kunye nezibonelelo kumashishini ovavanyo kunye nesiqinisekiso: inkqubo yenkonzo yomgangatho ophezulu, iqela lobugcisa eliqeqeshwe ngokunzulu, isiqinisekiso esikhawulezayo nesilula kunye nezisombululo zovavanyo.

● I-MCM isebenzisana nemibutho yasekuhlaleni ekumgangatho ophezulu evunyiweyo ngokusesikweni ebonelela ngezisombululo ezahlukeneyo, inkonzo echanekileyo neluncedo kubathengi.

Kwiminyaka yakutshanje, iingxelo zomlilo kunye nokuqhuma okubangelwa iibhetri ze-lithium-ion ziqhelekileyo.
Iibhetri ze-lithium-ion zenziwa ikakhulu ngezinto ezingalunganga ze-electrode, i-electrolyte kunye nezinto ezintle ze-electrode. Umsebenzi weekhemikhali we-graphite ye-electrode engafanelekanga kwimeko ehlawuliswayo yinto efana ne-lithium yensimbi. Ifilimu ye-SEI phezu komhlaba yayiza kubola kwiqondo lokushisa eliphezulu, kwaye i-lithium ion efakwe kwi-graphite yayiza kusabela nge-electrolyte kunye ne-binder polyvinylidene fluoride kwaye ekugqibeleni yayiza kukhulula ubushushu obuninzi.
Izisombululo ze-Alkyl carbonate eziphilayo zisetyenziswa ngokuqhelekileyo njenge-electrolytes, ezinokutsha. I-positive
Izinto ze-electrode zidla ngokuba yi-oxide yensimbi yenguqu, eneempawu ezinamandla ze-oxidizing kwimeko ehlawulisiweyo, kwaye ibole ngokulula ukukhulula i-oksijini kwiqondo lokushisa eliphezulu. Ioksijini ekhutshiweyo idibana ne-electrolyte ukuze i-oxidize, kwaye emva koko iphume ubushushu obuninzi.
Ngokucacileyo, ibhetri ye-ion ye-lithium ayinakuzinza xa ifudumeza ngobushushu obuphezulu. Noko ke, yintoni
ngenene kuya kwenzeka ukuba sihlala sifudumeza ibhetri? Apha senze uvavanyo lwangempela kwiseli ye-NCM egcwele ngokupheleleyo nge-voltage ye-3.7 V kunye nomthamo we-106 Ah.
Iindlela zoVavanyo:
1. Kwiqondo lobushushu begumbi (25±2℃), iseli enye iqala ukukhutshelwa kumda wombane osezantsi ngomda wangoku.
ye-1C kwaye ushiye imizuzu eyi-15. Emva koko sebenzisa i-1C rhoqo yangoku ukuhlawulisa kwi-voltage yomda ophezulu kunye nokutshintsha
Ukutshaja rhoqo kwamandla ombane, yeka ukutshaja xa ukutshaja kwangoku kuhla ukuya kwi-0.05C, kwaye uyibeke ecaleni
imizuzu eyi-15 emva kokutshaja;
