Hāʻawi ʻo QuantumScape i ka ʻikepili kūlana paʻa. Uku 4 C, kū i 25 C, 0-> 80%. i loko o 15 minuke

ʻO QuantumScape, kahi hoʻomaka e hoʻomohala i nā cell electrolyte paʻa, haʻaheo e pili ana i nā ʻāpana o kāna mau cell. He mea kupanaha ko lākou mau mana: ʻae lākou i ka hoʻopiʻi ʻana ma 4 ° C, kū a hiki i 25 ° C, hāʻawi i nā density ikehu ma waena o 0,3-0,4 kWh / kg a ma kahi o 1 kWh / l. ʻIke ʻo JB Straubel, ka mea nāna i hoʻokumu iā Tesla, he mea hoʻokūkū.

QuantumScape paʻa-mokuʻāina pūnaewele i Volkswagen kaʻa ma hope o 5 makahiki?

Ka papa o nā mea

• QuantumScape paʻa-mokuʻāina pūnaewele i Volkswagen kaʻa ma hope o 5 makahiki?
  • E hoʻopaʻa ana ma 4 C me ka hoʻohaʻahaʻa ʻole
  • ʻOi aku ma mua o 800 mau hana hana me ~ 10% degradation
  • Ma hope o nā mea a pau, nā loulou i nā mokulele?
  • 'Oha

Ua kaulana ʻo QuantumScape i ʻelua manawa i ka wā i hala: hoʻokahi, i ka wā i lilo ai ʻo Volkswagen i mea kuleana nui o ka hui, a ʻo ka lua o ka manawa, i ka manawa i lilo ai ʻo JB Straubel, ka mea hoʻokumu o Tesla, i lālā o ka papa alakaʻi. I kēia manawa ua lilo ia i mea leo nui no ke kolu o ka manawa: ua hoʻokuʻu ka hui i nā hopena o kāna noiʻi. He mea kupanaha ia no kekahi mau kumu: hōʻike ʻia ka nui o ka nui maʻamau i hana ʻia ma ka mahana maʻamau (30 degere Celsius), a ʻike ʻia nā hopena e hana hou ʻia.

ʻO ka QuantumScape Ceramic Cage kahi pā maʻalahi e like me ka nui o kahi kāleka pāʻani. Ma ka ʻaoʻao ʻākau o luna, hiki iā ʻoe ke ʻike i ka pelekikena o ka hui, ʻo Jagdeep Singh (c) QuantumScape.

He aha kā mākou e kamaʻilio nei? ʻO nā pūnaewele QuantumScape nā pūnaewele lithium e hoʻohana ana i kahi electrolyte paʻa ma kahi o kahi electrolyte wai, me ka ʻole o kahi anode ʻokoʻa. Aia ko lākou anode i nā ion lithium i ka wā e hoʻouka ai (Li-metal). Ke hoʻokuʻu ʻia ke kelepona, hele nā ​​ion lithium i ka cathode, pau ka anode.

Ke kiʻi hoʻolālā o kahi kelepona lithium-ion hou (hema) a me kahi cell QuantumScape. I loko o ke kelepona maʻamau e hele mai ana mai luna mai, loaʻa iā mākou kahi electrode, kahi graphite / silicon anode, he membrane porous, kahi cathode kumu lithium, a me kahi electrode. Hoʻokomo ʻia kēia mau mea āpau i kahi electrolyte e hoʻomaʻamaʻa i ke kahe (c) o nā ion QuantumScape.

E hoʻopaʻa ana ma 4 C me ka hoʻohaʻahaʻa ʻole

ʻO kahi holomua nui ka hiki ke hoʻopiʻi i nā cell QuantumScape a hiki i 4 ° C me ka luku ʻole iā lākou. ʻAʻohe degradation, no ka mea, hiki i ka electrolyte ceramic ke kahe o nā ion lithium, akā ʻaʻole e ʻae i ka lithium dendrites e ulu. 4 C 'o ia hoʻi me ka 60 kWh pākaukau e hōʻea mākou i ka mana hoʻopiʻi o 240 kW, me 80 kWh ua 320 kW, etc.. I ka manawa like, e hoʻopaʻa mākou i ka 80 pakeneka i 15 mau minuke, no laila ʻaʻole e emi iki ka mana hoʻopiʻi ma mua o ka palena kiʻekiʻe - ʻo ia ka 192 a me 256 kW, kēlā me kēia.

E lilo ia mau mana i ka hoʻopiha houʻana o ka laulā ma ka wikiwiki o +1 200 km / h, i.e. +20 km / min... ʻO ka hoʻomaha ʻana he ʻumikumamālima mau minuke e hohola i kou mau iwi a me kahi lua e hāʻawi iā ʻoe ma kahi o 300 mau kilomita a i ʻole 200 mau kilomita o ke ala ākea.

He mea hoihoi nō hoʻi ka hiki ʻana o ka "customization" koʻikoʻi o nā cell. Ua hoʻokiʻekiʻe ka hui i nā hoʻokolohua a hiki i 25 C. Ke manaʻo nei mākou e hoʻohana "wale" 20 C, hiki i kahi kaʻa me kahi pākaukau 60 kWh ke kū i nā kiʻi 1,2 MW!

ʻOi aku ma mua o 800 mau hana hana me ~ 10% degradation

ʻO kekahi pōmaikaʻi nui o nā cell QuantumScape ʻo kā lākou kaʻa kiʻekiʻe. Hiki maʻalahi lākou i nā pōʻai 800 i manaʻo ʻia (hana = piha piha a hoʻokuʻu) ma 1 ° C a hoʻohiki ʻoi aku ka lōʻihi ma ka mana haʻahaʻa - a hiki ke loaʻa ka hope i nā kaʻa uila.

Me he mea lā ʻaʻole nui ka 800 mau hana hana, akā inā mākou e kau i kēia waiwai ma ka mīkini, loaʻa iā mākou nā helu nui. E ʻōlelo mākou ua hui pū ʻia nā cell QuantumScape i kahi pākaukau 60 kWh. Hiki iā ʻoe ke hoʻokele maʻalahi ma mua o 300 mau kilomita. ʻO 800 mau pōʻai o ka hana he mileage ma kahi o 240 tausani mau kilomita (kiʻi ma luna).

Me kēia mileage, e paʻa mau ana nā mea e pili ana i ka 90 pakeneka o ko lākou hiki, no laila e ʻae lākou iā ʻoe e hoʻokele ʻaʻole ʻoi aku ma mua o 300 mau kilomita, akā 300 mau kilomita me ka ʻole o ka recharging! Inā hoʻomau ka hoʻohaʻahaʻa laina, ʻaʻole mākou i ʻike e pili ana, ma 480 80 mau kilomita e hōʻea mākou ma kahi o XNUMX pakeneka o ka mana a pēlā aku.

Hoʻohui mākou i kēia lā ʻo ka hōʻailona no ka hoʻololi ʻana a hoʻoponopono ʻana paha i kahi pākaukau he mana o 65-70 pakeneka o ka mana kumu.

Ma hope o nā mea a pau, nā loulou i nā mokulele?

ʻO JB Straubel, ka mea hoʻokumu o Tesla a i kēia manawa he lālā o ka papa alakaʻi o QuantumScape, ʻike i ka holomua o ka ʻoihana ma ke ʻano he holomua.... Hoʻoikaika ʻo ia ʻaʻole maʻamau ka nui o ka piʻi ʻana o ka mana, a ua ana ʻo Tesla i ka holomua i nā pākēneka helu hoʻokahi i nā makahiki i hala. ʻO nā hōʻikeʻike mai nā hoʻomaka ʻē aʻe e nānā pinepine i nā ʻāpana i koho ʻia a haʻalele i nā mea ʻē aʻe, ʻoiai ʻo QuantumScape i hōʻike i kekahi mau ana e pili ana i ka lōʻihi a me ka ukana a me ka hoʻomanawanui.

I kona manaʻo, hiki i nā mea hou ke ʻae i ka hana ʻana i nā mokulele uila me nā pae i kamaʻāina iā mākou.

'Oha

ʻAʻohe o nā kiʻi i hōʻike i nā pūnaewele QuantumScape i hoʻopaʻa ʻia. Ke hoʻoholo nei e ka animation, ua pehu loa lākou. ʻO ka ʻokoʻa ke nānā aku ma ka liʻiliʻi o 2-3 mau manawa ʻoi aku ka nui ma mua o ke ʻano o nā cell lithium-ion me nā anodes graphite-based, hiki ke lilo i palena i ka wā e hoʻokumu ai i nā pihi mana kiʻekiʻe.

Pono e ʻike ʻia (kokoke 1,5 mau hola o nā mea waiwai):

Kiʻi wehe: QuantumScape (c) Ke ʻano o nā pūnaewele QuantumScape
