Kodi chingachitike ndi chiyani ngati mukuwotcha batri ya lithiamu mosalekeza?,
Mabatire,

▍Kodi ANATEL Homologation ndi chiyani?

ANATEL ndichidule cha Agencia Nacional de Telecomunicacoes chomwe ndi boma la Brazil kuti lizipereka ziphaso zovomerezeka komanso zodzifunira. Kuvomereza ndi kutsata njira zake ndizofanana pazogulitsa zapakhomo ndi zakunja ku Brazil. Ngati zogulitsa zikugwira ntchito ku chiphaso chokakamiza, zotsatira zoyesa ndi lipoti ziyenera kugwirizana ndi malamulo ndi malamulo omwe ANATEL adafunsa. Satifiketi yogulitsa iyenera kuperekedwa ndi ANATEL poyamba zinthu zisanagawidwe pakutsatsa ndikuyikidwa kuti zigwiritsidwe ntchito.

▍Ndani ali ndi udindo pa ANATEL Homologation?

Mabungwe ovomerezeka aboma la Brazil, mabungwe ena ovomerezeka ndi ma lab oyesa ndi ANATEL certification Authority pakuwunika njira yopangira zinthu, monga njira yopangira zinthu, kugula, kupanga, pambuyo pa ntchito ndi zina zotero kuti zitsimikizire kuti chinthucho chikuyenera kutsatiridwa. ndi Brazil standard. Wopanga adzapereka zikalata ndi zitsanzo zoyesa ndikuwunika.

▍Chifukwa chiyani MCM?

● MCM ili ndi zaka 10 zokumana nazo zambiri komanso zothandizira pakuyesa ndi certification: machitidwe apamwamba kwambiri, gulu laukadaulo lodziwa bwino kwambiri, ziphaso zachangu komanso zosavuta komanso zothetsera zoyezetsa.

● MCM imagwira ntchito ndi mabungwe angapo odziwika bwino mdera lanu omwe amapereka mayankho osiyanasiyana, olondola komanso osavuta kwa makasitomala.

M'zaka zaposachedwapa, malipoti a moto ngakhale kuphulika kwa mabatire a lithiamu-ion ndi ofala.
Mabatire a lithiamu-ion amapangidwa makamaka ndi zinthu zopanda ma elekitirodi, ma electrolyte ndi zinthu zabwino zama elekitirodi. The mankhwala ntchito ya negative elekitirodi chuma graphite mu mlandu boma ndi pang'ono ngati zitsulo lithiamu. Kanema wa SEI pamtunda amatha kuwola pakutentha kwambiri, ndipo ma ayoni a lithiamu ophatikizidwa mu graphite amatha kuchita ndi electrolyte ndi binder polyvinylidene fluoride ndipo pamapeto pake amamasula kutentha kwambiri.
Alkyl carbonate organic solutions amagwiritsidwa ntchito ngati ma electrolyte, omwe amatha kuyaka. Zabwino
Elekitirodi zinthu zambiri kusintha zitsulo okusayidi, amene ali wamphamvu oxidizing katundu mu mlandu boma, ndipo mosavuta kuwola kumasula mpweya kutentha kwambiri. Mpweya wotulutsidwa umakhudzidwa ndi electrolyte kuti ukhale ndi okosijeni, kenako umatuluka kutentha kwambiri.
Apperately, batire ya lithiamu ion ingakhale yosakhazikika ikatenthedwa ndi kutentha kwakukulu. Komabe, chiyani
kwenikweni zingachitike ngati tipitiriza kutentha batire? Apa tidayesa kwenikweni ku cell ya NCM yokhala ndi magetsi a 3.7 V ndi mphamvu ya 106 Ah.
Njira Zoyesera:
1. Pa kutentha kwa firiji (25 ± 2 ℃), selo limodzi limatulutsidwa koyamba kumagetsi otsika ndi magetsi
1 C ndikusiya kwa mphindi 15. Kenako gwiritsani ntchito 1C nthawi zonse kuti mupereke voteji yapamwamba ndikusintha
Pakuchajisa voteji nthawi zonse, siyani kuyitanitsa pomwe magetsi atsika mpaka 0.05C, ndikuyiyika pambali kuti
Mphindi 15 mutatha kulipiritsa;
