He aha ka hopena inā e hoʻomau mau ana i ka pā lithium?,
ʻO nā ʻanuʻu,

▍He aha ka ANATEL Homologation?

He pōkole ʻo ANATEL no Agencia Nacional de Telecomunicacoes ʻo ia ka mana aupuni o Brazil e hōʻoia i nā huahana kamaʻilio no ka palapala koi a me ka manawaleʻa. ʻO kāna ʻae ʻia a me nā kaʻina hana e like me nā huahana ʻo Brazil a me nā huahana ʻē aʻe. Inā pili nā huahana i ka hōʻoia koi, pono ka hopena o ka hoʻāʻo a me ka hōʻike e like me nā lula a me nā lula i kuhikuhi ʻia e ANATEL. E hāʻawi mua ʻia ka palapala huahana e ANATEL ma mua o ka hoʻolaha ʻia ʻana o ka huahana ma ke kūʻai ʻana a hoʻokomo ʻia i loko o ka noi kūpono.

▍ ʻO wai ke kuleana no ANATEL Homologation?

ʻO nā hui aupuni aupuni o Brazil, nā kino hōʻoia ʻē aʻe i ʻike ʻia a me nā labs hoʻāʻo ʻo ANATEL ka mana hōʻoia no ka nānā ʻana i ka ʻōnaehana hana o ka ʻāpana hana, e like me ke kaʻina hana hoʻolālā huahana, kūʻai, kaʻina hana, ma hope o ka lawelawe a pēlā aku e hōʻoia i ka huahana kino e hoʻokō ʻia. me ke kūlana Brazil. Hāʻawi ka mea hana i nā palapala a me nā laʻana no ka hoʻāʻo a me ka loiloi.

▍No ke aha MCM?

● Loaʻa iā MCM nā makahiki he 10 ka nui o ka ʻike a me nā kumuwaiwai i ka hoʻāʻo ʻana a me ka ʻoihana hōʻoia: ʻōnaehana lawelawe kūlana kiʻekiʻe, ʻenehana loea hohonu, hōʻoia wikiwiki a maʻalahi a me nā hoʻonā hoʻāʻo.

● Hana pū ʻo MCM me nā hui kūloko kūlana kiʻekiʻe e hāʻawi ana i nā hāʻina like ʻole, lawelawe pololei a maʻalahi no nā mea kūʻai aku.

I nā makahiki i hala iho nei, ʻike pinepine ʻia nā hōʻike o ke ahi a me nā pahū ʻana e nā pā lithium-ion.
Hoʻokumu nui ʻia nā pākahi Lithium-ion me nā mea electrode maikaʻi ʻole, electrolyte a me nā mea electrode maikaʻi. ʻO ka hana kemika o ka graphite material electrode maikaʻi ʻole i ke kūlana i hoʻopiʻi ʻia e like me ka lithium metala. E decompose ana ke kiʻiʻoniʻoni SEI ma luna o ka ʻili i ka wela kiʻekiʻe, a ʻo nā ion lithium i hoʻokomo ʻia i loko o ka graphite e hana me ka electrolyte a me ka polyvinylidene fluoride binder a hoʻokuʻu i ka wela nui.
Hoʻohana maʻamau ʻia nā mea hoʻoheheʻe alkyl carbonate ma ke ʻano he electrolytes, hiki ke puhi ʻia. ʻO ka maikaʻi
ʻO ka mea electrode ka mea maʻamau he hoʻololi metala oxide, nona nā waiwai oxidizing ikaika i ka mokuʻāina i hoʻopiʻi ʻia, a maʻalahi hoʻi e decomposes e hoʻokuʻu i ka oxygen ma ke kiʻekiʻe wela. Hoʻopili ka oxygen i hoʻokuʻu ʻia me ka electrolyte e oxidize, a laila puka mai ka wela nui.
ʻO ke ʻano, ʻaʻole paʻa ka pā lithium ion i ka wā e hoʻomehana ai me ka wela kiʻekiʻe. Eia naʻe, he aha
e hiki mai ana inā hoʻomau mākou i ka hoʻomehana ʻana i ka pākaukau? Ma ʻaneʻi ua hana mākou i kahi hoʻāʻo maoli i kahi kelepona NCM piha piha me ka volta o 3.7 V a me ka mana o 106 Ah.
Nā ʻano hoʻāʻo:
1. Ma ka lumi wela (25 ± 2 ℃), hoʻokuʻu mua ʻia ke kelepona hoʻokahi i ka uila palena haʻahaʻa me kahi manawa.
o 1C a waiho no 15 mau minuke. A laila e hoʻohana i ka 1C mau manawa e hoʻopiʻi i ka volta palena luna a hoʻololi
i ka hoʻouka uila mau, hoʻōki i ka hoʻopiʻi ʻana i ka wā e hāʻule ai ke kahe o ka manawa i 0.05C, a waiho ʻia no ka
15 mau minuke ma hope o ka hoʻouka ʻana;
