ʻO nā pūnaewele pākahi o nā hanauna hou: Kia e-Niro me NCM 811 mai SK Innovation, hilinaʻi ʻo LG Chem iā NCM 811 a me NCM 712

Ua hoʻomākaukau ʻo PushEVs i kahi papa inoa hoihoi o nā ʻano kelepona a LG Chem a me SK Innovation e hana ai i ka wā e hiki mai ana. Ke ʻimi nei nā mea hana i nā koho e hāʻawi ana i ka mana kiʻekiʻe me ka haʻahaʻa haʻahaʻa loa o ka cobalt pipiʻi. Ua hoʻohui pū mākou i ka papa inoa Tesla.

Ka papa o nā mea

• ʻO nā pūnaewele pākahi o ka wā e hiki mai ana
  • • LG Chem: 811, 622 -> 712
    • SK Innovation i NCM 811 w Kia Niro EV
    • ʻO Tesla I NCMA 811
  • He aha ka maikaʻi a he aha ka hewa?

ʻO ka mea mua, he mea hoʻomanaʻo iki: ʻo kahi mea ʻo ia ka papa kūkulu kumu o kahi pā traction, ʻo ia hoʻi, kahi pākaukau. Hiki i ke kelepona ke hana ma ke ʻano he pākaukau. ʻO nā pila i loko o nā kaʻa uila he pūʻulu o nā cell i mālama ʻia e kahi ʻōnaehana BMS.

Eia ka papa inoa o nā ʻenehana a mākou e nānā ai i nā makahiki e hiki mai ana ma LG Chem a me SK Innovation.

LG Chem: 811, 622 -> 712

Ua hoʻopuka mua ʻo LG Chem i nā cell me NCM 811 cathode (Nickel-Cobalt-Manganese | 80% -10% -10%), akā hoʻohana ʻia kēia mau mea i nā kaʻa. ʻO ke kolu o ka hanauna o nā pūnaewele me ka ʻike nickel kiʻekiʻe a me ka ʻike cobalt haʻahaʻa e manaʻo ʻia e hāʻawi i ka nui o ka mālama ʻana i ka ikehu. Eia kekahi, e uhi ʻia ka cathode me ka graphite, kahi e wikiwiki ai ka hoʻouka ʻana.

ʻenehana Bateri (c) BASF

Hoʻohana ʻia ka ʻenehana NCM 811 i nā cell cylindrical., oiai i loko o kahi ʻeke aia mākou i ka ʻenehana NCM 622 - a aia kēia mau mea i loko o nā kaʻa uila. I ka wā e hiki mai ana, e hoʻohui ʻia ka alumini i ka sachet a e hoʻololi ʻia nā ʻāpana o ka metala i NCMA 712. E hana ʻia nā cell o kēia ʻano me ka liʻiliʻi o 10% cobalt mai 2020.

> No ke aha i koho ai ʻo Tesla i nā cell cylindrical inā makemake nā mea hana ʻē aʻe i nā cell flatter?

Manaʻo mākou i ka NCM 622, a me ka NCMA 712, e hele mua i nā kaʻa Volkswagen: Audi, Porsche, VW paha.

Nā ʻeke o LG Chem - ma ka mua ma ka ʻākau a hohonu - ma ka laina hana (c) LG Chem

SK Innovation i NCM 811 w Kia Niro EV

Hoʻomaka ʻo SK Innovation i ka hana ʻana o nā cell me ka hoʻohana ʻana i ka ʻenehana NCM 811 hou loa i ʻAukake 2018. ʻO ke kaʻa mua e hoʻohana ʻia ʻo ia ke Kia Niro uila. Hiki i nā kelepona ke hoʻonui i Mercedes EQC.

No ka hoʻohālikelike: Hoʻohana mau ʻo Hyundai Kona Electric i nā mea NCM 622 hana ʻia e LG Chem.

ʻO Tesla I NCMA 811

Hana ʻia ʻo Tesla 3 me ka hoʻohana ʻana i ka ʻenehana NCA (NCMA) 811 a ʻoi aku ka maikaʻi. Ua ʻike ʻia kēia i ka wā o ka hōʻuluʻulu ʻana o nā hopena o ka hapaha mua o 2018. Ua like lākou me nā cylinders a… liʻiliʻi ka ʻike e pili ana iā lākou.

> 2170 (21700) pūnaewele i loko o Tesla 3 ʻoi aku ka maikaʻi ma mua o nā kelepona NMC 811 i ka _future_

He aha ka maikaʻi a he aha ka hewa?

Ma ka laulā: ʻo ka haʻahaʻa o ka ʻike cobalt, ʻoi aku ka liʻiliʻi o ka hana ʻana i nā cell. No laila, pono e emi ke kumu kūʻai no ka pākaukau e hoʻohana ana i nā kelepona NCM 811 ma mua o nā mea maka no ka pākaukau e hoʻohana ana i ka NCM 622. Eia naʻe, hiki i nā cell 622 ke hāʻawi i ka mana kiʻekiʻe no ke kaumaha like, akā ʻoi aku ka uku.

Ma muli o ka piʻi wikiwiki ʻana o ke kumukūʻai o ka cobalt ma nā mākeke honua, ke neʻe nei nā mea hana i 622 -> (712) -> 811.

Hoʻomaopopo: hoʻohana kekahi mau mea hana i ka hōʻailona NCM, ʻo NMC kekahi.

Kiʻi ma luna: SK Innovation NCM 811 sachet me nā electrodes i ʻike ʻia ma nā ʻaoʻao ʻelua.
