Hāʻawi ka Tesla lab i nā mea e hiki ke kū i nā miliona miliona.
ʻO kahi keʻena noiʻi noiʻi i hoʻolimalima ʻia e Tesla e hana i nā cell lithium-ion i kaena i kahi kemika cell hou. Mahalo i ka cathode NMC (nickel-manganese-cobalt) a me ka electrolyte hou, pono lākou e kū i 1,6 miliona mau kilomita o ka mile kaʻa.
I kēia manawa, hoʻohana ka hapa nui o ka honua kaʻa i nā ʻano ʻano o nā pūnaewele NMC, ʻoiai ʻo Tesla e hoʻohana i kahi hui like ʻole o nā mea: NCA (nickel-cobalt-aluminum). ʻO nā pākahi Tesla hou e kū i ka 480 a 800 tausani mau mile mile. Eia nō naʻe, manaʻo ʻo Elon Musk e hōʻoia e ʻoi aku ka lohi o kā lākou degradation, i hiki iā lākou ke kūpaʻa e like me nā mīkini a me nā kino - a hiki i 1,6 miliona mau mile mile.
E like me ka mea i hōʻike ʻia e ka portal Electrek (kumu), ʻo Jeff Dahn's laboratory, nāna e noiʻi i nā hiki ke hoʻomaikaʻi i nā cell Li-ion no Tesla, i hōʻike i nā hopena o kāna hana. Hoʻohana nā pūnaewele hou i ka cathode "single crystal" cathode NMC 532 a me kahi electrolyte kiʻekiʻe. Ma hope o ka hoʻāʻo ʻana, i kekahi mau manawa a hiki i ʻekolu makahiki, Ua hoʻoweliweli ka poʻe ʻepekema i ka ʻōlelo ʻana e hiki i nā cell ke kū i 1,6 miliona mau kilomita i loko o kahi kaʻa. a i ʻole he iwakālua makahiki i loko o kahi hale kūʻai ikehu.
ʻOiai me ka mahana o ka hoʻouka ʻana o nā cell e hoʻomehana ana i 40 degere, ua paʻa lākou 70 pākēneka ma hope o 3 mau uku piha, pono e unuhi i loko mileage ma kahi o 1,2 miliona mau kilomita. ʻOiai e mālama ana i ka mahana o 20 degere ma hope o 3 miliona mau mile mile e hāʻule ka mana o nā pūnaewele i ka approx 90 pakeneka o ka mana mua.
> Makemake ʻo Tesla e hana i ka 1 GWh o nā cell i kēlā me kēia makahiki. I kēia manawa: 000 GWh, 28 manawa emi
Ma kahi hoʻokolohua like ʻole, kūʻai nā ʻenekini lithium-ion i kūʻai ʻia ma kahi o 1 mau pōʻai, pono e unuhi i 000 mau mile mile. ʻOiai pono e hoʻohui ʻia ma ʻaneʻi ʻo nā cell i hoʻohana ʻia i ka ʻoihana automotive he mau hui like ʻole o nā electrolytes, ʻo ka hana nui ʻo ia ka hoʻolōʻihi i ke kaʻina degradation.
Pono e heluhelu (kumu), no ka mea, hoʻonohonoho ka hana i ka ʻike e pili ana i nā cell lithium-ion a hōʻike i ka holomua i hana ʻia i nā makahiki 4-6 i hala.
Kiʻi wehe: 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 402035 i hoʻāʻo ʻia i loko o nā ʻeke ma ka ʻaoʻao o ke kālā ʻelua kālā Kanada, DOWN, kiʻi ma ka hema) degradation o nā pūnaewele i ho'āʻoʻia e kū'ē i nā pūnaewele hoʻohālike, DOWN, diagram akau) ke ola o ke kelepona ma muli o ka mahana i ka wā e hoʻouka ai (c) Jessie E.
