Mahalo i ka hui pū ʻana me CATL no ka manawa mua ma Kina. Ma lalo o $ 80 no kWh ma ka pae pae?
He leka huna mai Reuters. Ke hui pū nei ʻo Tesla me CATL e hoʻolauna i kahi pākaukau lithium-ion hou haʻahaʻa i hoʻololi ʻia ma Kina. Kapa ʻia kēia he "miliona mile [1,6 miliona kilomita] pākaukau," akā ʻaʻole pololei ka ʻike.
Nā Pūnaewele Tesla Hou = LiFePO4? NMC 532?
Wahi a Reuters, ʻoi aku ka liʻiliʻi o ka "miliona mile" hou a ʻoi aku ka lōʻihi. I ka hoʻomaka ʻana, ua manaʻo ʻia e hana ʻia nā cell e ka CATL o Kina, akā makemake ʻo Tesla e hoʻomohala i ka ʻenehana i hiki iā ia ke lohi - no ka hopena o nā leaks ʻē aʻe - hoʻomaka i kāna hana ponoʻī.
ʻAʻole hāʻawi ʻo Reuters i nā kikoʻī e pili ana i nā cell, no laila hiki iā mākou ke noʻonoʻo e pili ana i kā lākou haku. Hiki iā lākou ke lilo i mau mea lithium hao phosphate (LFP, LiFePO4), ka mea i hoʻohālikelike i nā huaʻōlelo ʻelua ("cheap", "long lived"). Hiki iā ia ke lilo i ʻano hou o nā keena lithium-ion me NMC 532 (nickel-manganese-cobalt) cathodes mai kahi aniani hoʻokahi.
> Ke noi nei ʻo Tesla i kahi patent no nā cell NMC hou. He mau miliona kilomika i kaʻa a me ka liʻiliʻi liʻiliʻi
ʻAʻole paha he "cheap" ka mea hope ma muli o ka ʻike cobalt i ka cathode (20 pakeneka), akā ʻo wai ka mea ʻike inā ua uhi piha ʻo Tesla i nā mea āpau i ka noi patent? Ua hoʻāʻo ʻia paha ka ʻano NMC 721 a i ʻole 811? ... Haʻaheo ka mea hana i ka hiki ke hoʻokō a hiki i ka 4 mau manawa hoʻoiho.
ʻO ka mea hope akā ʻaʻole ka mea liʻiliʻi loa, hiki i kēia mau keena CATL he mana i hoʻomaikaʻi ʻia o ka poʻe i loaʻa me NCA (Nickel-Cobalt-Aluminum) cathodes, aia ka liʻiliʻi ma mua o 2018 pākēneka kobalt mai ka liʻiliʻi o 3.
ʻO ka "kumu" i ʻōlelo ʻia e ka ʻoihana e ʻōlelo nei waiwai o kēia manawa o nā pūnaewele LiFePO4 hana ʻia e CATL - ma lalo o 60 kālā no 1 kWh... Me ka pākaukau holoʻokoʻa, ʻaʻole ia ma mua o $ 80 no ka kilowatt-hola. No nā pūnaewele NMC cobalt haʻahaʻa, kokoke ke kumukūʻai pākaukau i $ 100 / kWh.
Wahi a Reuters, he haʻahaʻa loa ke kumukūʻai o ka hana ʻana i nā kelepona pohihihi i hiki ke hoʻohālikelike ʻia nā kaʻa e holo ana iā lākou me ke kumukūʻai o nā kaʻa puhi ahi (kumu). Eia hou, he mea pohihihi: ke kamaʻilio nei mākou e pili ana i ka hāʻule ʻana o nā kumukūʻai no ka Tesla e kūʻai ʻia nei? A i ʻole he kumu hoʻohālike mai kekahi mea hana ʻike ʻole ʻia? Ua ike wale ia e hele mua nā pūnaewele i Kina, a hiki ke hoʻolauna ʻia i nā mākeke ʻē aʻe i "nā kaʻa Tesla hou.".
Hiki iā mākou ke lohe hou aʻe e pili ana i kēia i ka lā Battery, e hana ʻia ana i ka hapa ʻelua o Mei.
> ʻO Tesla Battery Day "hiki i ka waena o Mei." Malia paha…
Kiʻi wehe: Tesla Model S (c) pūʻolo pila mai Ted Dillard. ʻAʻole pono nā loulou hou he cylindrical; hiki ke hoʻonohonoho ʻia i nā ʻano like ʻole.
E hoihoi paha kēia iā ʻoe:
