Ka lōʻihi: Ua hoʻohana mua ka mea hana i nā keena lithium-ion me nā anodes silika. Nā koho? Mai kamaʻilio kāua
Ua hoʻopiʻi ka pelekikena o Sila Nano ua hele wale nā pūnaewele lithium-ion me nā anodes silicon i ke ala mua. ʻO kēia ka Whoop 4.0 fitness tracker, i ʻōlelo ʻia e ka mea hana he pākaukau me 17 pākēneka kiʻekiʻe o ka ikehu kiʻekiʻe ma mua o ka hāmeʻa mua.
ʻO nā anodes silikon ka mea mua i nā mea hale liʻiliʻi a i ka wā e hiki mai ana, no ka laʻana, ma Mercedes
ʻAʻole makemake ʻo Sila Nano e hōʻike i nā ʻāpana o nā cell hou (voltage ma waena o nā electrodes, ka nui o ka ikehu, etc.). ʻAʻole ia e hōʻike i ka mea nāna i hana pono i nā pila no ka mea he mea hana wale ʻo Sila Nano i ka anode pauda silicon a ua hana ʻia nā cell e kekahi. No laila, loaʻa iā mākou ka 17 pakeneka i ʻōlelo ʻia a me ka ʻōlelo ʻana e hiki ke hoʻohana ʻia nā ʻekena hou a me ke ola pākaukau like ʻoiai e hōʻemi ana i ka nui o ka hāmeʻa e 1/3 (kumu, loaʻa kālā; kumu).
Hoʻohana ʻia nā anodes cell lithium-ion hou i nā ʻano kalapona like ʻole, i kekahi manawa me ka hoʻohui ʻana o ke silika. Loaʻa ka maikaʻi o ka anode silicon i hiki iā ia ke hoʻopaʻa a mālama a hiki i ka 10 mau manawa ʻoi aku ka lithium ma mua o kahi anode graphite. ʻO ka manaʻo no laila Hiki ke loaʻa i kahi pākaukau e hoʻohana ana i ke silika he 10 mau manawa ka nui.
Eia naʻe, ʻaʻole maikaʻi loa ka ʻoiaʻiʻo iā mākou. ʻO ka capacitance kiʻekiʻe o ke ʻano silicon, ʻo ia ka 1) i ka manawa mua o ka hana o ke kelepona, ke hana ʻia kahi papa passivation, ʻoi aku ka nui o nā lithium immobilized mau loa. A ʻo kēia ka 2) ʻoi aku ka nui o nā ion lithium i nā hale silika (pono lākou e loaʻa ma kahi), kahi e alakaʻi ai i ka luku ʻana i ka anode. Ma ka hopena ʻoi aku ka nui o ka lithium no ka hana ʻana i ke kelepona anode silicon (= ke kumu kūʻai kiʻekiʻe) ʻO Odraz nā mīkini hoʻopaʻa hou e ālai ana i ka pehu ʻana o ka hale.
Me he mea lā ua hiki iā Sila Nano ke hoʻoponopono i ka liʻiliʻi o kekahi o nā pilikia a ma ka manawa like e hana i kahi hana no ka hana nui o nā anodes silicon. I nā makahiki he 10 i hala iho nei, ua wikiwiki ka hana hana i hoʻokahi kaukani manawa (1 manawa). No nā pūnaewele lithium-ion me nā anodes silicon e hele i loko o nā kaʻa, pono e hoʻonui ʻia ke kaʻina hana o kēia manawa e kahi kumu o 000 (kumu). Wahi a ka hui i nā makahiki 100-5 e hiki mai ana, e paʻi nā pā lithium-ion i ka mākeke ma $ 10 no ka kilowatt-hola, kākoʻo i ka hoʻopiʻi wikiwiki a kū i 10 pōʻai, 000 makahiki o ka hana.
ʻO Sila Nano kekahi o nā hui e kōkua ana iā Mercedes (Daimler) e hoʻokumu i kāna mau hale hana pākaukau lithium-ion ponoʻī.
E hoihoi paha kēia iā ʻoe:
