Mea hana Supercapacitor: Ke hana nei mākou i nā pā graphene e hoʻopaʻa ana i 15 kekona

He pule hou, pākaukau hou. Ua hoʻomaka ʻo Skeleton Technologies, kahi mea hana o nā supercapacitors, e hana i nā cell e hoʻohana ana i ka graphene i hiki ke hoʻopaʻa ʻia i 15 kekona. I ka wā e hiki mai ana, hiki iā lākou ke hoʻokō (ma mua o ka hoʻololi ʻana) i nā pā lithium-ion i nā kaʻa uila.

ʻO Graphene "SuperBattery" me ka hoʻouka wikiwiki loa. ʻO ka supercapacitor graphene kūpono

Ka papa o nā mea

• ʻO Graphene "SuperBattery" me ka hoʻouka wikiwiki loa. ʻO ka supercapacitor graphene kūpono
  • E hoʻonui ka supercapacitor i ka laulā a hoʻolohi i ka hoʻohaʻahaʻa cell

ʻO ka pōmaikaʻi nui loa o Skeleton Technologies '"SuperBattery" - a i ʻole supercapacitor - ʻo ia ka hiki ke hoʻopaʻa iā ia i kekona. Mahalo a pau i ka "curved graphene" a me nā mea i hoʻomohala ʻia e ka Karlsruhe Institute of Technology (KIT), e like me ka German portal Electrive (kumu).

Hiki ke hoʻohana ʻia kēlā mau supercapacitors i ka wā e hiki mai ana i nā hybrids a me nā kaʻa kaʻa wahie, kahi e hiki ai iā lākou ke holo wikiwiki mai ka honua o nā uila. I kēia manawa, hoʻohana nā hybrids a me nā FCEV i nā ʻeke liʻiliʻi liʻiliʻi, a ʻaʻole hiki iā mākou ke hana i ka mana kiʻekiʻe me nā mana liʻiliʻi.

Ke haʻaheo nei ʻo Skeleton Technologies ʻo ka Kinetic Energy Recovery System (KERS) e pili ana i nā supercapacitors ua hoʻemi i ka hoʻohana wahie i loko o kahi kaʻa mai 29,9 a i 20,2 lita no 100 mau kilomita (kumu, kaomi i ka Play Video).

E hoʻonui ka supercapacitor i ka laulā a hoʻolohi i ka hoʻohaʻahaʻa cell

I nā uila, e hoʻopiha nā graphene supercapacitors i nā pūnaewele lithium-ione hoʻokuʻu iā lākou i nā ukana kaumaha (hard acceleration) a i ʻole nā ​​ukana kaumaha (heavy recuperation). ʻO ka mea i hana ʻia e Skeleton Technologies e hiki ai ke hana i nā pākahi liʻiliʻi ʻaʻole pono e koi i kahi ʻōnaehana hoʻoluʻu paʻakikī.

E hiki no 10% hoʻonui i ka hiki a he 50 pakeneka ke ola pila.

No hea mai ka manaʻo e hoʻohui i nā ʻōhua kuʻuna wale nō? ʻAe, ʻo nā supercapacitors i hana ʻia e ka ʻoihana he haʻahaʻa haʻahaʻa haʻahaʻa. Hāʻawi lākou i ka 0,06 kWh/kg, aia ma ka pā me nā pūnaewele NiMH. ʻO nā pūnaewele lithium-ion kiʻekiʻe loa a hiki i nā pae o 0,3 kWh/kg, me kekahi mau mea hana e hoʻolaha nei i nā waiwai kiʻekiʻe:

> Manaʻo ʻo Musk i ka hiki ke hana nui o nā cell me ka density o 0,4 kWh / kg. ʻO ke kipi? Ma ke ano

ʻAʻole kānalua, ʻo ka hemahema ka haʻahaʻa haʻahaʻa o ka ikehu. ʻO ka pōmaikaʻi o nā graphene supercapacitors ka helu o nā pōʻai hana ma mua o 1 uku / hoʻokuʻu.
