Nava: ʻO kā mākou mau nanotube electrodes he 3 manawa ka nui a hāʻawi i 10 mau manawa i ka mana i loko o nā keena lithium-ion.
He pule hou a me ka pākaukau hou. Ua ʻōlelo ka mea hana supercapacitor Farani, ʻo Nawa, ua hoʻomaka ʻo ia e hana i nā electrodes nanotube hou loa no nā pā lithium-ion. Ua manaʻo ʻia ma muli o ka hoʻonohonoho like ʻana o nā nanotubes, hiki iā lākou ke mālama i ʻekolu manawa ʻoi aku ka nui ma mua o nā anodes kalapona.
Nā Anodes 3D Hou o Nawa: ʻOi aku ka ikaika, ʻoi aku ka maikaʻi, ʻoi aku ka wikiwiki, ʻoi aku ka ikaika
Hana ʻia nā anodes lithium-ion hou me ka graphite a i ʻole carbon activated (a i ʻole carbon activated mai ka graphite), no ka mea, hiki i kā lākou hale porous ke mālama i ka nui o nā ion. I kekahi manawa, hui ʻia ke kalapona me ka silikoni a hoʻopuni ʻia e kahi nano-coating e kaupalena i ka pehu ʻana o ka mea.
Hiki iā ʻoe ke lohe e pili ana i nā pono no ka hoʻohana ʻana i ka silika maʻemaʻe, wahi a Tesla a i ʻole Samsung SDI.
> Nā ʻāpana Tesla hou loa: format 4680, anode silicon, "diameter optimal", hana hana ma 2022.
Wahi a Nava, paʻakikī loa ke ʻano o ke kalapona no ka neʻe ʻana i nā ion. Ma kahi o ka carbon, makemake ka hui e hoʻohana i nā nanotubes carbon, i hōʻike ʻia ua hoʻohana ʻia i nā supercapacitors o ka mea hana. Hoʻokumu ʻia nā nanotubes like ʻole i nā "notches" i hiki ke noho ʻoluʻolu. ʻŌlelo:
Hiki ke manaʻo ʻia aia nā nanotubes a pau i loko o ka anode i ke ʻano o ka neʻe ʻana o nā ion ma waena o lākou a hiki i ke koho ʻana i kahi kūpono. "Me ka hele ʻole a puni nā hale porous o kahi anode maʻamau, e hele wale nā ion i kahi nanometer ma kahi o nā micrometers, e like me ke ʻano o nā electrodes maʻamau," wahi a Nava.
Hōʻike ka ʻōlelo hope loa e hiki nō i nā nanotubes ke hana ma ke ʻano he cathodes - e hilinaʻi kā lākou hana i ka mea e kau ana ma luna o ko lākou ʻili. ʻAʻole ʻae ʻo Nef i ka hoʻohana ʻana i ke silika no ka mea e hoʻopaʻa ʻia e nā nanotubes kalapona e like me ka hale paʻa, no laila ʻaʻole hiki i ka hale ke pehu. Paʻa ka pilikia Crush!
> E hoʻohana i nā pūnaewele lithium-ion ma waho o ka papa me kahi anode silika. ʻOi aku ka wikiwiki ma mua o ka hoʻopiha ʻana me ka hydrogen
He aha ke ʻano me nā ʻāpana o nā cell e hoʻohana ana i nā nanotubes? ʻAe, e ʻae lākou:
- i ka hoʻohana 'ana o ʻO 10 mau manawa ʻoi aʻe ka hoʻouka ʻana a me ka hoʻokuʻu ʻana i ka manahe aha kēia manawa
- hoʻokino ʻO nā pila me ka ikaika o ka ikehu he 2-3 manawa kiʻekiʻe mai nā mea hou aku,
- e hoʻolōʻihi i ke ola pākaukau e ʻelima a ʻumi paha manawano ka mea, ʻaʻole e ʻae nā nanotubes i nā kaʻina hana e luku ai i nā cell lithium-ion (kumu).
ʻO ke kaʻina hana o ka hoʻolikelike ʻana i nā nanotubes i ka lālani he mea maʻalahi loa ia, i ʻōlelo ʻia he ʻano hana like i hoʻohana ʻia no ka uhi ʻana i nā aniani a me nā kiʻi kiʻi kiʻi me kahi uhi anti-reflective. Haʻaheo ʻo Nawa hiki iā ia ke ulu i nā nanotubes like me ka wikiwiki a hiki i 100 micrometers (0,1 mm) i kēlā me kēia minuke - a hoʻohana i kēia ʻenehana i kāna mau supercapacitors.
Inā he ʻoiaʻiʻo nā ʻōlelo a Nava a kūʻai ʻia nā electrodes hou, ʻo ia ka manaʻo iā mākou:
- ʻoi aku ka māmā o nā kaʻa uila ma mua o nā kaʻa puhi ahi, akā me kahi lōʻihi lōʻihi,
- ka hiki ke hoʻopiʻi i nā mea uila me ka mana o 500 ... 1 ... 000 kW, ʻoi aku ka pōkole ma mua o ka refueling,
- ka piʻi ʻana o ka mileage o nā mea uila me ka ʻole o ka pono e hoʻololi i ka pākaukau mai ka 300-600 tausani i kēia manawa i 1,5-3-6 miliona mau kilomita,
- ʻoiai e mālama ana i ka nui o kēia manawa: hiki ke hoʻouka hou ʻia, e ʻōlelo i kēlā me kēia pule ʻelua.
ʻO ka hoa hana mua o Navah ʻo ia ka mea hana pākaukau Farani ʻo Saft, e hui pū ana me PSA Group a me Renault i ka European Battery Alliance.
