QuantumScape: Ua hoʻomaka mākou e hoʻāʻo i nā mea paʻa 10-layer ma kahi ʻano pāʻoihana. ʻO nā pila ma hope o 2 mau makahiki a ʻoi aku paha
ʻO QuantumScape, kekahi o nā mea hoʻomaka e hana ana i nā cell electrolyte paʻa, haʻaheo i ka hoʻomaka ʻana i nā hoʻokolohua me nā cell 10-layer. I ka makahiki 2022, makemake ka ʻoihana e hōʻike i nā cell me nā papa he ʻumikūmālua a hoʻolālā e hoʻokuʻu i ka pūʻulu hoʻāʻo mua i kūpono i nā kaʻa ma 2023.
Pono nā pūnaewele electrolyte paʻa ikaika a paʻa. Hoʻomau mau lākou
ʻO nā pūnaewele i hoʻomohala ʻia e QuantumScape he ʻōnaehana He mea hao me ka anode... Aia ka anode i ka lithium ma kahi electrode i ka wā e hoʻopiʻi ʻia ai ka pākaukau a luku ʻia ke hoʻokuʻu ʻia. I loko o ke kelepona lithium-ion maʻamau, hana ʻia ka anode me kekahi ʻano kalapona (e like me ka graphite), i kekahi manawa doped me ke silikoni. Inā ʻaʻohe graphite i loko o ke kelepona, ʻaʻole ia e lawe i kahi ākea, no laila hiki ke hoʻohana ʻia ka hapa nui o ka leo a me ke kaumaha o ke kelepona no ka mālama ʻana i ka uku.
Ua manaʻo ʻia ʻo QuantumScape ʻo ia ka hoʻomaka hoʻohiki maikaʻi loa i ka wā e hiki mai ana i nā cell solid-state, akā ʻo kēia ʻoihana e ʻōlelo nei. e lohi ka hoʻomohala ʻana... Ma hope o hoʻokahi a me ʻehā-layer cell, ua hiki ke hana i 1-layer cell, i loko o nā ʻumi mua o nā pōʻai o ka hana ma ke ʻano 4C-10C (ka hoʻouka ʻana a me ka hoʻokuʻu ʻana me ka mana e like me ka hiki ke kelepona) a Hōʻike ke ʻano C / 1-C / 1 i kahi pōʻino iki. Akā he 3-3 wale nō kēia no nā kelepona liʻiliʻi, ʻōlelo pololei ka ʻoihana e pili ana i ka hana mua:
Nā hoʻāʻo mua o 10-layer QuantumScape cell. Hōʻike ka pakuhi he 20-36 mau pōʻaiapuni wale nō o QuantumScape i hoʻopau ʻia.
ʻO ka maikaʻi o ka hoʻokolohua ʻo ia ka lawe ʻia ʻana ma kahi mahana kokoke i ka lumi wela (hoʻohālikelike: ka mahana hana o ka pā uila eCitaro mai BlueSolutions). A ke hana nei mākou me nā pūnaewele nui ma ka format 7,5 × 8 cm. He mea hoʻohui pū kekahi ka hiki ke hoʻohui i ka quantumScape electrolyte paʻa me ka lithium-iron-phosphate cathodes... ʻO ka mea hope loa, ʻo ka mea maikaʻi o QuantumScape, ka mea i papa inoa i nā ʻāpana hoʻāʻo kūpono.
ʻO nā pūnaewele electrolyte paʻa o ka hanauna i hala, 4-layer cell. ʻO nā pūnaewele hana maikaʻi loa i nalowale ma kahi o 5-6 pakeneka o ko lākou hiki ma hope o 400 mau manawa o ka hoʻohana. ʻO ka hoihoi, ʻo nā puʻupuʻu i ʻike maopopo ʻia o ka hoʻololi ʻana i ka ikehu hoʻokuʻu (ʻo ia hoʻi, ka mana pākaukau) ma mua koke o ka helu pōʻai 400 (c) QuantumScape
Akā ʻo ia ka hopena o nā pōmaikaʻi. ʻO nā pūnaewele metala Lithium e pehu i ka wā o ka hana ʻana no ka mea hana ka lithium i hoʻopaʻa mua ʻia i kahi mea ʻokoʻa i loko o lākou - ka anode. No laila, hoʻāʻo ʻo QuantumScape iā lākou ma 3,4 ea e hoʻolōʻihi i ke kaʻina hana. ʻO ia ke ʻano o ka depressurization hiki ke alakaʻi i ka pau ʻana o ka pākaukau i ka wā e hiki mai ana. ʻO ka mea like, ʻoiaʻiʻo, me ke kaʻa (ʻaʻole maikaʻi ka puncture), akā ʻaʻole pono ke kaʻa i ka 1/3 o ke kaʻa.
Eia naʻe, ʻo ke kaomi pahu kiʻekiʻe paha ka mea liʻiliʻi loa o nā pilikia. ʻAe, ʻo 10-layer cell kahi pae waena i hoʻohālikelike ʻia i nā cell me nā papa heʻumikūmālua, ʻo ka hopena hope loa i 2022. E hāʻawi wale lākou i ka nui o ka ikehu e hiki ai ke hoʻokūkū me nā cell lithium-ion maʻamau e pili ana i ke kumukūʻai / hana [ʻAʻole ʻōlelo ʻo QuantumScape]. E ʻike ʻia nā cell prototype mua i kūpono no ka hoʻohana ʻana i ka automotive ma ka mea kanu QS-0 ma Kaleponi ma 2023, ʻelua mau makahiki mai kēia manawa, ʻoiai ke hana nei ka ʻoihana e hoʻonui i kāna hana ʻana i nā mea hoʻokaʻawale ceramic (electrolytes).
Paʻa 10-layer QuantumScape Cell (hema) a me ka laina annealing hou i hoʻokomo ʻia ma QS-0 (c) mea kanu QuantumSCape
ʻO ka hiki i ʻōlelo ʻia o ka hoʻohana ʻana i ka QuantumScape electrolyte i loko o nā pūnaewele LFP e nānā maikaʻi loa. Ma muli o kēia, loaʻa ia mau mea i ka ikehu ikehu o 0,6-0,7 kWh / l, e pili ana i nā pūnaewele lithium-ion hou loa me nā cathodes nickel-manganese-cobalt a me nā electrolytes wai. Kanaka kamaʻilio: me QuantumScape Porsche paʻa electrolyte hiki ke mālama i ka mana o ka pākaukau Taycan me ka hoololi ole i ka ipu me ka emi nui o kona kumukuai ma o ka hoʻohana ʻana iā LFP.
ʻAʻole manaʻo ʻia e kūʻai ʻia nā cell a hiki i ka manawa o 2023 a me 2024.
E hoihoi paha kēia iā ʻoe:
