E hoʻomaka ana ka papahana Europa LISA. ʻO ka pahuhopu nui: ka hana ʻana o nā pā lithium-sulfur me ka nui o 0,6 kWh / kg
Ma Ianuali 1, 2019, hoʻomaka ka papahana ʻEulopa LISA, ʻo ka pahuhopu nui ʻo ia ka hoʻomohala ʻana i nā cell Li-S (lithium-sulfur). Ma muli o nā waiwai o ka sulfur, ʻoi aku ka māmā ma mua o nā metala i hoʻohana ʻia i kēia lā, hiki i nā cell sulfur lithium ke hiki i kahi ikehu kūikawā o 0,6 kWh / kg. ʻO nā pūnaewele lithium-ion hou loa i kēia lā ma kahi o 0,25 kWh / kg.
Ka papa o nā mea
- Lithium Sulfur Cells: ʻO ka wā e hiki mai ana o nā kaʻa, mokulele a me nā kaʻa
- Pāhana LISA: nā pākaukau lithium-polymer kiʻekiʻe a kūʻai ʻole me ka electrolyte paʻa.
Ua hoʻāʻo nui nā kānaka ʻepekema e hana ana i nā kelepona uila i nā pūnaewele lithium sulfur no nā makahiki he nui. Maikaʻi ko lākou mana no ka mea ua hoʻohiki lākou ka pīhoihoi ikehu kiko 2,6 kWh/kg (!). I ka manawa like, ʻo ka sulfur kahi mea maʻalahi a hiki ke loaʻa no ka mea he huahana ʻōpala mai nā mea kanu mana lanahu.
Eia naʻe He hemahema no ka sulfur: ʻOiai e hōʻoiaʻiʻo ana ia i ke kaumaha o ke kelepona haʻahaʻa - ʻo ia ke kumu i hoʻohana ʻia ai nā cell Li-S i nā mokulele uila, ka haki ʻana i nā moʻolelo lele hoʻomaha ʻole - ʻo kāna mau waiwai physico-kemika e hana maikaʻi loa ia. hoʻoheheʻe koke i ka electrolyte... ʻO ia hoʻi: Hiki i kahi pākahiko Li-S ke mālama i ka uku nui no kēlā me kēia ʻāpana, akā i ka wā o ka hana ʻana ua luku ʻole ʻia..
> Hoʻohana ka pākaukau o Rivian i 21700 cell - e like me ka Tesla Model 3, akā ʻo LG Chem pū kekahi.
Pāhana LISA: nā pākaukau lithium-polymer kiʻekiʻe a kūʻai ʻole me ka electrolyte paʻa.
Manaʻo ʻia ka papahana LISA (lithium sulfur for safe road electrification) ma luna o 3,5 mau makahiki wale nō. Ua hui pū ʻia ʻo ia ma ka huina o 7,9 miliona euros, ʻo ia ka mea e like me 34 miliona zlotys. Aia ia e Oxis Energy, Renault, Varta Micro Battery, Fraunhofer Institute a me Dresden University of Technology.
Ke manaʻo nei ka papahana LISA e hoʻomohala i nā pūnaewele Li-S me nā electrolytes solid hybrid non-combustible. Pono e hoʻoponopono i ka pilikia o ka pale ʻana i nā electrodes, kahi e alakaʻi ai i ka hoʻohaʻahaʻa wikiwiki ʻana o nā cell. 'Ōlelo nā kānaka ʻepekema mai ka ikehu theoretical o 2,6 kWh / kg, ʻoiaʻiʻo 0,6 kWh / kg hiki ke loaʻa.
> ʻO ka Asphalt (!) E hoʻonui i ka hiki a me ka wikiwiki i ka hoʻopiʻi ʻana o nā pā lithium-ion.
Inā kokoke loa ia i kēia helu, me ke kaumaha o kekahi mau haneli kilokani E hāʻule ana nā ʻuala no nā kaʻa uila mai nā kakini (!) A ma kahi o 200 kilokani.... He kui paha kēia i loko o ka pahu o nā kaʻa hydrogen cell (FCEVs), ʻoiai ʻo nā pahu hydrogen o Toyota Mirai wale nō ma kahi o 90 kg.
E hoʻomohala ʻia ka papahana ma lalo o ka mana o Oxis Energy (kumu). Ua ʻōlelo ka hui ua hoʻokō ʻo ia i ka hana ʻana i nā cell me ka ikehu ikehu o 0,425 kWh / kg hiki ke hoʻohana ʻia i nā mokulele. Eia naʻe, ʻaʻole ʻike ʻia ko lākou ola a me ke kū'ē ʻana i nā pōʻai hoʻokuʻu.
> ʻO nā pākahi Li-S - kahi hoʻololi i nā mokulele, nā kaʻa a me nā kaʻa
