Ke noi nei ʻo Tesla i kahi patent no nā cell NMC hou. He mau miliona kilomika i kaʻa a me ka liʻiliʻi liʻiliʻi
Ua noi ʻo Tesla Canada i nā kelepona hou me nā cathodes NMC (Nickel-Manganese-Cobalt). Me he mea lā ʻo ia nā mea like a Jeff Dunn's lab i hoʻolālā ʻia no ka mea hana, a hiki iā ia ke hele i miliona mau kilomita me ka liʻiliʻi o ka lole a me ka waimaka.
E neʻe ʻo Tesla mai NCA a i NMC?
Ke hoʻohana nei ʻo Tesla i kēia manawa i nā keena lithium-ion me nā cathodes NCA, ʻo ia hoʻi, nickel-cobalt-aluminum, me ka liʻiliʻi ma mua o 10 pakeneka kobalt maʻiʻo, ma ka liʻiliʻi loa i ka Tesla Model 3. ʻO kēia hanana i loko ona iho, no ka mea, i loko o ka maikaʻi o nā keena hou NMC811 10 pakeneka cobalt cathodes. hoʻohana ʻia - akā hele mālie lākou, e hoʻoneʻe i nā mea NMC622.
> 2170 (21700) pūnaewele ma Tesla 3 ʻoi aku ka maikaʻi ma mua o NMC 811 i _future_
E like me kā Elon Musk i hoʻohiki ai, Pono e holo ʻo Tesla hou mai ka 0,48 a i ka 0,8 miliona mau kilomita ma kahi pākaukau. Eia nō naʻe, i ka wā e hiki mai ana, makemake ʻo ia e hoʻokele i 1,6 miliona mau kilomita ma ka mana pākaukau - ʻo ia ka mea e kākoʻo ai ke kino a me ka mana o ka Tesla Model 3.
A eia ua kōkua ʻia ʻo ia e nā hoʻokō o ka hale hana ʻo Jeff Dunn, i hana no Tesla no kekahi manawa a i ka mahina ʻo Kepakemapa 2019 i hoʻokiʻekiʻe ʻia i kahi ʻano kemika hou loa o nā electrolytes o nā cell lithium-ion me NMC532 cathodes.
Ma muli o ka hoʻohana ʻana i kahi cathode "hoʻokahi kristal" a me kahi electrolyte me nā mea hoʻohui i hoʻohana ʻia i kēia manawa i hoʻonui ʻia me nā dioxazolones a me nā nitriles o kahi ester o ka sulfite, ma muli o ke ʻano o ka electrolyte (kumu), hiki ke hoʻokō i kēia:
- ka emi ʻana o ka cell degeneration ma muli o ka ulu ʻana o ka passivation layer (SEI), kahi e hoʻopaʻa ai i nā ion lithium, nona ke kuleana no ka hiki,
- ʻoi aku ka maikaʻi o ke kelepona ma mua o ka mahana.
A) kiʻi microscopic o ka pauka NMC 532 B) kiʻi microscopic o ka ʻili electrode ma hope o ke kaomi ʻana, C) kekahi o nā cell i hoʻāʻo ʻia 402035 i loko o kahi ʻeke ma ka ʻaoʻao o ke kālā Kanada ʻelua kālā, DOWN, kiʻi ma ka hema) hoʻohaʻahaʻa ʻia o nā cell i hoʻāʻo ʻia. i hoʻohālikelike ʻia me ke kāʻei kua o nā cell model, DOWN, diagram ma ka ʻākau) cell lifetime versus temperature during charging (c) Jesse E. Harlow et al. / Journal of the Electrochemical Society
He mea paʻakikī kēia, akā he mea kupanaha nā hopena:
- He 70 pakeneka ka mana ma hope o 3 mau kaʻina hoʻoili ma 650 degere (ma kahi o 40 miliona mau kilomita),
- a hiki i ka 90 pakeneka mana ma hope o 3 miliona mau kilomitainā mālama ʻia ka mahana o ke kelepona ma 20 degere Celsius a ua hoʻokō ʻia ka hoʻouka ʻana ma 1 ° C (1x kaha pākaukau, ʻo ia hoʻi 40 kW me kahi pākaukau 40 kWh, 100 kW me kahi pākaukau 100 kWh, etc.).
ʻAʻole ʻike ʻia inā ʻo ka noi patent e kali nei ʻo ia ka mea e hoʻololi ʻo Tesla i ka NCA i NCM. I kēia manawa, ua ʻōlelo ʻole ʻia e ʻike ʻia nā cell lithium-ion NCM i nā hiʻohiʻona i hana ʻia ma Kina.
> ʻO Asphalt (!) E hoʻonui i ka hiki a me ka wikiwiki i ka hoʻopiʻi ʻana i nā pā lithium-ion.
Eia nō naʻe, palekana ka ʻōlelo ʻana ua mākaukau ka mea hana Kaleponi e hāʻawi i kāna mau patent. Ma ka paʻi ʻana i nā pepa e pili ana i nā mea hoʻohui electrolyte hou, makemake paha ʻo ia e hoʻolalelale i ka hana o ka honua ma luna o ka hanauna hou aku lithium cell.
Eia ka palapala patent piha a Tesla (hoʻoiho PDF HERE):
E hoʻomaopopo mai nā mea hoʻoponopono o www.elektrowoz.pl: i ka wā e hoʻomohala ana i kēia kumuhana, ua manaʻo mākou he kumukūʻai loa ka hana ʻana i kahi kaʻa uila Polish. ʻAʻole hiki iā mākou ke ʻike i kekahi ʻōlelo o nā dioxazolones a me ka sulfite ester nitriles ma ka Pūnaewele Polani. ʻO ia hoʻi, ʻaʻohe kanaka ma Polani i hiki ke hoʻomaopopo i kēia noi patent a me kāna mau hopena. Loaʻa iā mākou he mau kaukani PhD ma ke kākau ʻana, kūʻai aku, philology a me ka mōʻaukala, akā ke holomua nei ka holomua maoli ma kahi ʻē, ma ʻaneʻi, ma mua o ko mākou mau maka.
E hoihoi paha kēia iā ʻoe:
