Alise Project: Ua hiki i kā mākou mau pūnaewele lithium-sulphur i 0,325 kWh / kg, e hele ana mākou i 0,5 kWh / kg
ʻO ka Alise Project kahi papahana noiʻi i kākoʻo ʻia e ka European Union, e pili ana i nā hui 16 a me nā hui mai 5 mau ʻāina. Ua kaena wale nā kānaka ʻepekema ua hana lākou i kahi prototype Li-S (lithium-sulphur) cell me ka nui o ka ikehu o 0,325 kWh/kg. ʻO nā pūnaewele lithium-ion maikaʻi loa e hoʻohana ʻia nei a hiki i ka 0,3 kWh/kg.
Ka papa o nā mea
- Kiʻekiʻe kiʻekiʻe = ʻoi aku ka nui o ka pākaukau
- Li-S i ke kaʻa: ʻoi aku ka maikaʻi, ʻoi aku ka wikiwiki, ʻoi aku. ʻAʻole naʻe i kēia manawa
ʻO ka nui o ka ikehu kiʻekiʻe o ke kelepona ʻo ia ka hiki ke mālama i ka ikehu hou aʻe. ʻOi aku ka ikehu ma kēlā me kēia ʻāpana nuipaʻa nā pae kiʻekiʻe o nā kaʻa uila (me ka mālama ʻana i ka nui o ka pākaukau o kēia manawa), a i ʻole nā pae i kēia manawa me nā ʻōhua liʻiliʻi a māmā. ʻO kēlā me kēia ala, makemake mau ke kūlana no mākou.

He mea waiwai nui loa ia no ke aʻo ʻana i ka nui o ka ikehu no kēlā me kēia ʻāpana o nā mea. ʻO ka lithium a me ka sulfur nā māmā māmā, no laila ʻaʻole kaumaha ka mea ponoʻī. Ua hiki i ka papahana Alise ke hoʻokō i ka 0,325 kWh/kg, ma kahi o 11 pakeneka ʻoi aʻe ma mua o ka mea i koi ʻia e CATL o Kina i kāna mau keena lithium-ion hou.
> Haʻaheo ʻo CATL i ka haki ʻana i ka pale 0,3 kWh/kg no nā cell lithium-ion
ʻO kekahi o nā lālā o ka Alise Project, ʻo Oxis Energy, ua hoʻohiki mua i ka density o 0,425 kWh / kg, akā i ka papahana EU, ua hoʻoholo nā ʻepekema e hoʻohaʻahaʻa i ka density i mea e hoʻokō ai, i waena o nā mea ʻē aʻe: ka mana hoʻopiʻi kiʻekiʻe. Eia naʻe, i ka hopena makemake lākou e neʻe i ka 0,5 kWh/kg (kahi kumu).
Hoʻokumu ʻia ka pākaukau ma nā modula i hoʻopiha ʻia me nā cell Li-S (c) Alise Project.
Li-S i ke kaʻa: ʻoi aku ka maikaʻi, ʻoi aku ka wikiwiki, ʻoi aku. ʻAʻole naʻe i kēia manawa
ʻO nā kelepona i hoʻokumu ʻia ma ka lithium a me ka sulfur ke nānā aku nei i ka hoʻohiki, akā ua pau ka hoihoi. Hoʻomaopopo lākou iā ʻoe he lōʻihi ke ala e hele ai. O kahi laʻana Ke kū nei nā pila Li-S ma kahi o 100 mau kaʻina hoʻokuʻu hoʻoiho.ʻoiai ʻo 800-1 mau pōʻaiapuni i manaʻo ʻia he haʻahaʻa kūpono loa i kēia lā, a aia nā prototypes e hoʻohiki ana i nā pōʻai uku 000-3:
> Haʻaheo ka lab o Tesla i nā cell i hiki ke kū i nā miliona mau kilomita [Electrek]
He pilikia nō hoʻi ka mahana. ma luna o 40 degere Celsius, hoʻoheheʻe koke nā mea Li-S. Makemake nā mea noiʻi e hoʻokiʻekiʻe i kēia paepae i ka liʻiliʻi he 70 degere, ʻo ka mahana e hiki mai ana me ka wikiwiki loa.
Eia nō naʻe, aia kekahi mea e hakakā ai, no ka mea, ʻaʻole pono kēia ʻano kelepona i ka cobalt pipiʻi, paʻakikī ke loaʻa, akā ʻo ka lithium haʻahaʻa a me ka sulfur maʻamau. Ma muli o ka nui o ka ikehu theoretical i ka sulfur a hiki i ka 2,6 kWh/kg - kokoke i ʻumi mau manawa o nā pūnaewele lithium-ion maikaʻi loa i hoʻokomo ʻia i kēia lā.
