He mea hou i kahi kaʻa me kahi pākaukau graphene? GAC: ʻAe, ma Aion V ke hoʻāʻo nei mākou i kēia manawa. E hoʻopaʻa ana i ka 6 C!
Ua ʻōlelo ka GAC Kina ua loaʻa iā ia kahi hōʻoia palekana koa no ka "graphene battery". Manaʻo ʻia e ʻae i ka hoʻouka ʻana me ʻelua mau mana o kēia lā: i kēia lā ʻo ka piʻi o ka holomua ma ke kahua o nā uila he 3-3,5 C (mana = 3-3,5 x kaha pākahi), ua ʻōlelo ʻia ka pākaukau graphene i ke kaʻa GAC e hoʻohana i ka 6 C.
ʻO nā ʻona Graphene - he aha ka mea e hāʻawi mai iā mākou?
Ka papa o nā mea
- ʻO nā ʻona Graphene - he aha ka mea e hāʻawi mai iā mākou?
- GAC Aion V - he aha kā mākou ʻike
E hoʻomanaʻo: i loko o nā pākahi lithium-ion maʻamau me kahi electrolyte wai, hana mau ʻia nā anodes me ke kalapona a i ʻole ka carbon doped me ke silika. Hiki ke hana ʻia nā cathodes mai ka lithium-nickel-manganese-cobalt (NCM) a i ʻole lithium-nickel-cobalt-aluminum (NCA). I ka wā o ka hana pākaukau, neʻe nā ion lithium ma waena o nā electrodes ʻelua, hāʻawi a ʻae paha i nā electrons. Ma hea kahi e kūpono ai ka graphene i kēia mau mea a pau?
ʻAe, ke hoʻouka ʻia me ka mana kiʻekiʻe, hiki i nā atom lithium ke hana i nā protrusions i kapa ʻia dendrites. No ka pale ʻana iā lākou, hiki iā mākou ke hoʻololi i ka electrolyte wai i mea paʻa ʻaʻole e komo nā tabs - ʻo ia ke ʻano o ka hana ʻana i nā ʻeke paʻa (solid electrolyte). Hiki iā mākou ke haʻalele i ka electrolyte wai, akā e hoʻopili i ka cathode me kahi mea me ka ikaika tensile kiʻekiʻe loa a i ka manawa like me ka permeable i nā ion.
A eia ka graphene e hoʻopakele - kahi ʻāpana ʻāpana o nā ʻātoma kalapona i hoʻopaʻa ʻia.
GAC Aion V - he aha kā mākou ʻike
I kēia manawa e neʻe kākou i ka ʻōlelo hoʻolaha GAC. Ke hoʻāʻo nei kekahi mea hana Kina i nā pā graphene i ke kumu hoʻohālike Aion V ma Mohe, Kina. ʻIke ʻia, ua loaʻa iā ia kahi palapala palekana koa no lākou, e ʻae paha iā lākou e hoʻohana ʻia i nā kaʻa uila. ʻO ka ikaika o ka ikehu o nā pākahi graphene inā paha 0,28 kWh / kg, ka mea i hāʻawi ʻia e nā pūnaewele NCM kiʻekiʻe - ʻaʻohe mea holomua ma aneʻi (kumu).
ʻO ka holomua liʻiliʻi ka manaʻolana ola. 1,6 tausani pōʻaiapuni hana. ʻAʻole ʻike maopopo ʻia nā pōʻaiapili i ʻōlelo ʻia, akā inā ʻo 1 C (hoʻouka / hoʻokuʻu ʻana me ka mana e like me ka hiki o ka pākaukau), maikaʻi loa ka hopena. ʻO ka maʻamau o ka ʻoihana he 500-1 cycles.
ʻO ka hoihoi nui mana hoʻouka ʻoi loa... Pono ia 6 C, i.e. he pākaukau me ka mana o, e ʻōlelo, 64 kWh - e like me ka Kia e-Niro - hiki iā mākou ke hoʻouka me ka mana kiʻekiʻe o 384 kW. ʻO Tesla Model 3 me kahi pākahiko 74 kWh hiki ke piʻi i ka 444 kW! ʻO ia hoʻi ma hope o 5 mau minuke e hoʻopaʻa ana e hoʻopau ʻia ke kaʻa ʻaʻole emi ma lalo o 170 mau kilomita o ka laulā maoli (200 WLTP pūʻulu).
ʻO ka pakuhi graphene i hoʻohana ʻia ma ka GAC Aion V ʻOi aku ka nui o ke kumukūʻai ma mua o ka pākaukau lithium-ion maʻamau... Pono e hoʻomaka ka hana Serial o ke kaʻa me nā pihi hou i Kepakemapa 2021.

ʻO ka palapala hoʻoponopono www.elektrowoz.pl: ʻO ka noi i hōʻike ʻia o ka graphene i loko o kahi kelepona lithium-ion kekahi o nā noi hiki. Hōʻike ka noiʻi i nā makahiki i hala iho nei ʻo kēia ʻenehana kūikawā ʻoi loa ka holomua, no laila ke manaʻo nei mākou e hele ka GAC i ke ala graphene-NMC. Eia naʻe, ʻaʻole hōʻike ka mea hana kaʻa i nā kikoʻī, no laila pono e noʻonoʻo ʻia ka wehewehe ʻana i luna.
