No laila, kaua! Tesla: nā mea cylindrical wale nō, 4680. Volkswagen: nā mea ʻāpana ʻāpana like ʻole

I ka lā Battery i ʻOkakopa 2020, ua hoʻolaha ʻo Tesla i ka hoʻokumu ʻana i kahi format cell cylindrical hou, ka 4680, e kū koke ana i ka laina kaʻa. ʻEono mahina ma hope mai, ua hoʻolaha ʻo Volkswagen i nā loulou cuboid maʻamau e lilo i kumu no ka aneane o ka hui holoʻokoʻa, me nā kaʻa.

Ke hopu nei ʻo Volkswagen, e hana ana i kahi paʻi o 2-3 mau makahiki wale nō i hoʻohālikelike ʻia me Tesla

Ka papa o nā mea

• Ke hopu nei ʻo Volkswagen, e hana ana i kahi paʻi o 2-3 mau makahiki wale nō i hoʻohālikelike ʻia me Tesla
  • He aha ka manaʻo o kēia mau mea no ka poʻe maʻamau?

ʻEkolu ʻano o nā kelepona i hoʻohana ʻia i nā kaʻa uila:

• pōʻaiapili (cylindrical shape) hoʻohana nui ʻia e Tesla,
• huinahā lōʻihi (English prismatic), paha ka mea maʻamau i waena o nā mea hana kuʻuna, ua hoʻoholo ʻo ia e hana Manaʻo Volkswagen i loko o ka "cell hoʻokahi",
• ʻeke (ʻeke), kahi i ʻike ʻia ma kahi o ka mea nui loa ʻo ia ke "ʻoki" i ka nui o ka pākaukau mai kahi mana i hāʻawi ʻia.

Loaʻa i kēlā me kēia ʻano nā mea maikaʻi a me nā pōʻino: pōʻaiapili ʻo ia ka mea kaulana loa (hoʻohana ʻia i nā kāmera a me nā kamepiula), no laila ʻo Tesla lāua ʻo Panasonic i hoʻolalelale iā lākou. Hāʻawi pū lākou i kahi kiʻekiʻe o ka palekana. Sachet ʻae lākou e hoʻokō i nā density ikehu kiʻekiʻe, akā pono nā mea hoʻolālā e hoʻomanaʻo e hiki iā lākou ke hoʻonui nui i ka leo no ka mea ʻaʻohe o lākou puka e hoʻokuʻu i nā kinoea hiki. Cuboids ʻO kēia nā mea i loko o nā ʻeke i loko o kahi pahu paʻakikī, ʻo ke ala maʻalahi loa e hōʻuluʻulu iā lākou (no ka laʻana, mai nā poloka) kahi pākaukau i mākaukau, ʻoi aku ka ikaika o ka mīkini.

Ua hoʻohana mua ʻo Volkswagen i nā cell rectangular, akā me he mea lā ua hoʻohālikelike ʻia kā lākou ʻano i ka hoʻolālā ʻana o ke kaʻa. Nā pūnaewele hui pū pono e puka mai no ka manawa mua ma 2023, a i ka makahiki 2030 pono lakou e helu a hiki i ka 80 pakeneka o na keena hoohana a pau:

ʻAʻole e hoʻonohonoho ʻia nā cell hou i nā modula (mai ke kelepona a hiki i ka hoʻopaʻa ʻana), a me ke ʻano like (form) pono e loaʻa nā ʻano kemika like ʻole i loko:

• ma na kaa makamae loa e makemake lakou LFP pūnaewele (ka hao hao phosphate)
• me nā huahana nui e pili ana nā pūnaewele kiʻekiʻe i ka manganese (a me kekahi nickel)
• ma nā hiʻohiʻona i koho ʻia puka mai NMC pūnaewele (nickel-manganese-cobalt cathodes),
• ... a ma kahi o lākou, hoʻomanaʻo pū ʻo Volkswagen i nā cell electrolyte paʻa, ʻoiai nona ka 25% o nā ʻāpana o QuantumScape. Ua ʻae aku nā pūnaewele paʻa i ka piʻi ʻana o 30% i ka laulā a me ka uku i loko o 12 mau minuke ma kahi o 20 (ʻikepili e pili ana i nā prototypes):

No ka anode, ʻaʻole hana ka ʻoihana i nā preconceptions, akā i kēia lā ke hoʻāʻo nei i ka graphite me ke silika. I kēia manawa ka ʻike: Porsche Taycan a me Audi e-tron GT loaʻa nā anodes silikamahalo i hiki ke hoʻopiʻi ʻia me kahi mana kiʻekiʻe (i kēia manawa: a hiki i 270 kW).

ʻO ka hopena makemake ʻo Volkswagen e hoʻohana nā loulou ma ke ʻano he mea hoʻolālā o ke kaʻa (pūnaewele i ka mīkini) a me he mea lā e hoʻololi ʻia nā cell standardized no kēlā. Eia naʻe, ma mua o ka hiki ʻana o ka Pūʻulu i kēia pae, pono e hele i kēia pae. pākaukau me nā modules (cell-to-pack) - ʻo ka mīkini mua i kūkulu ʻia ma kēia ʻano kumu hoʻohālike i hana ʻia e ka papahana Artemis Audi... Hiki paha iā mākou ke ʻike i kahi manaʻo manaʻo o kēia kaʻa i 2021.

Pākuʻi modular. He loulou kona iwi iwi. ʻO ka ʻanuʻu aʻe nā loulou ʻaʻole ballast, akā he mea hoʻolālā o ke kaʻa - Volkswagen cell-to-car (c)

Hiki ke hana ʻia nā mea hou i nā hale hana 6 a Volkswagen e makemake ai e hoʻomaka e 2030. (kekahi me na hoa). ʻO ka mea mua i kūkulu ʻia e Northvolt e kūkulu ʻia ma Skelleftea, Suedena. Aia ka lua ma Salzgitter (Kelemānia, mai 2025). Aia ke kolu ma Sepania, Pokukala a i ʻole Farani (mai 2026). I ka makahiki 2027, pono e hoʻokuʻu ʻia kahi mea kanu ma ʻEulopa Hikina, me Polani., ʻae ʻia ʻo Czech Republic a me Slovakia - ʻaʻohe hoʻoholo i kēia manawa. ʻAʻole ʻike ʻia kahi e kūkulu ʻia ai nā mea kanu hope ʻelua.

He aha ka manaʻo o kēia mau mea no ka poʻe maʻamau?

Mai ko mākou manaʻo ʻO ka pōmaikaʻi nui o nā pūnaewele i hoʻohui ʻia ʻo ka hōʻemi ʻana i nā kumukūʻai hana... No ka mea e lilo lākou i ke ao holoʻokoʻa, hiki i nā mīkini i hoʻonohonoho ʻia ma ke ala like ke hana ma nā mea kanu āpau o ka hopohopo. Hoʻokahi keʻena noiʻi ua lawa no hoʻokahi ʻano kemika. ʻO ia wale nō paha paha hoʻololi i nā kumukūʻai haʻahaʻa no nā kaʻa uila.

A inā ʻaʻole ia e hana, hiki iā Tesla, Volkswagen, Audi a me Skoda ke kau i ke kumu kūʻai ma ke koena o ka mākeke. No ka mea, ʻo ka hoʻohana ʻana i nā mea hoʻolako o waho (e ʻike iā Hyundai, BMW, Daimler,…) ʻo ia hoʻi ka liʻiliʻi o ka maʻalahi a me nā kumukūʻai kiʻekiʻe.
