Samsung Graphene Batteries: 0-80 pakeneka i 10 mau minuke a makemake lākou i ka mahana!
Ma Nature, ua kaʻana like nā ʻepekema Samsung SDI i kā lākou noiʻi ʻana ma nā pūnae uila graphene-coated cathode (GB-NCM). Manaʻo maikaʻi nā hopena: ʻaʻole makaʻu nā pila i nā wela kiʻekiʻe, loaʻa ka nui o ka mālama ʻana i ka ikehu kiʻekiʻe a hiki ke hoʻouka koke ʻia.
Ka papa o nā mea
- No ke aha e lohi ai ke kaʻa uila?
- ʻO nā ʻoniʻoni Graphene Samsung SDI GB-NCM
Ma kahi hoʻolaha paʻi hou e pili ana i ka loaʻa ʻana o Shell iā IONITY, ua hoʻohiki ʻo Shell e hoʻokomo i nā haneli kilowatt (kW) DC a me DC. ʻoiai ʻO ka charger kahi ʻāpana wale nō o ka puzzle. Pono ke kaʻa e komo i kēia mana - a ma laila kahi e hoʻomaka ai ke alapiʻi..
Ma luna aʻe o 150-200 kW, e wela koke nā pila i hiki ʻole i nā ʻōnaehana hoʻoluʻu ke hoʻomaha iā lākou. Ke alakaʻi nei kēia i ka hoʻonui ʻana i ka nui o nā filament lithium i loko a me ka hoʻohaʻahaʻa wikiwiki ʻana o nā cell, kahi e hoʻemi nui ai i ka hiki o ka pā.
> E hoʻi mai ʻo Opel Ampere E ?! He pilikia ko ka PSA Group a makemake e koi kālā mai General Motors.
No laila, hoʻopiʻi ʻia nā kaʻa o kēia manawa me ke au pololei (DC) me ka mana o ka 120 kW (koke: 150 kW), i ʻole e hōʻino i ka pākaukau. ʻO ia ke kumu e hana nei nā ʻepekema i nā ʻaʻa i hiki ke hoʻopaʻa i ka mana a me nā wela kiʻekiʻe aʻe.
ʻO nā ʻoniʻoni Graphene Samsung SDI GB-NCM
ʻO nā ʻaniani graphene Samsung SDI he mau pākahi lithium-ion maʻamau ʻo nickel-cobalt-manganese electrode (NCM) me hoʻokahi hoʻomaʻemaʻe: graphene spheres ma ka ʻili. Hōʻike ʻia kēia mau hale ma kahi kokoke ma ka ʻākau:
Me ka graphene He 800 Wh no ka lita (Wh / L) ka ikehu o Samsung SDI.ʻo ia ke kumu kūʻai o ka hanauna hou aʻe NCM 811, pono e kū i ka mākeke ma hope o 2021.
I ka manawa like, mālama ʻia nā pākaukau i ka 78,6% o ko lākou hiki ma hope o 500 charge / discharge cycles i nā mahana ma waena o 0 a me 60 degere Celsius. ʻAʻole i pau: ua hoʻonui ʻia me nā lei graphene makemake nui nā ʻōhua i ka mahana!
Ma 60 degere, loaʻa iā lākou ka nui o ka mālama ʻana i ka ikehu, ʻo ia hoʻi, ʻoi aku ka nui o lākou: 444 watt-hola no ka kilo o ke kelepona ma 60 degere me 370 watt-hola no ka kilo ma 25 degere! No laila, ʻo ka hoʻomaʻamaʻa ʻana i ka pākaukau i ka wā e hoʻopiʻi ana e pōmaikaʻi ka mea hoʻokele.
Akā ʻaʻole ʻo ia wale nō: hiki i nā pila ke hoʻopaʻa i ka mana kiʻekiʻe. Ma 5 degere Celsius, hiki ke hoʻopaʻa i ka pākaukau mai 0 a 80 pakeneka ma lalo o 10 mau minuke!
> ʻenehana pākaukau hou = 90 kWh Nissan Leaf a me 580 km ākea ma kahi o 2025
Pono e heluhelu: ʻatikala ma Nature
E hoihoi paha kēia iā ʻoe:
