"ʻO kā mākou alumini-ion (aluminum-ion) pūnaewele e hoʻopiʻi i nā manawa 60 wikiwiki ma mua o nā pūnaewele lithium-ion." Auwe! :)

He pule hou a me ka pākaukau hou. Ua ʻōlelo ʻo Australia's Graphene Manufacturing Group ua hoʻomohala i nā cell e pili ana i ka graphene a me ka alumini (kahi mea). 'Ōlelo lākou "he 60 manawa wikiwiki lākou ma mua o nā pūnaewele lithium-ion maikaʻi loa," a "hiki iā lākou ke mālama iʻekolu manawaʻoi aku ka ikaika ma mua o nā pūnaewele alumini-ion'ē aʻe."

Al-ion GMG pūnaewele. Ua maikaʻi loa nā mea a pau

Ka papa o nā mea

• Al-ion GMG pūnaewele. Ua maikaʻi loa nā mea a pau
  • He mea maʻalahi ka alumini, he pipiʻi ka graphene

Pono nā pūnaewele ion alumini GMG ma ke ʻano o nā mea pihi pihi a mākou i ʻike ai, no ka laʻana, nā kī a i ʻole nā ​​​​mea pāʻani liʻiliʻi. Akā ʻoi aku ka wikiwiki o ka hoʻouka ʻana he kanaono manawa kani kupanaha. Ua loaʻa iā ia e like me ka helu ana ka hope mai 1 a 5 minuke. Paʻa ikehu "ʻekolu manawa ʻoi aku ma mua o nā mea ʻē aʻe me nā ion alumini." 0,15-0,16 kWh / kg.

Hiki i ka hui ke kaena i hoʻokahi ʻāpana: ka hiki ke loaʻa i ka 7 kW o ka mana mai 1 kilogram o nā cell. O ia nā hīnaʻi i loko o ke kaʻa uilahe 250 kilokani kona kaumaha, hiki iā lākou ke hoʻoulu a hiki i ka 1,75 MW (!, 2 km) o ka mana ma ko lākou kiʻekiʻe... He kani kosmic, ma ka liʻiliʻi ma ka pepa. ʻO ka ʻaoʻao i lalo ka volta hana o ke kelepona, i kēia manawa ʻo 1,7 V.

Ke hoʻohana nei i ka graphene, kahi prototype cell ion alumini i hoʻomohala ʻia e GMG

ʻO ka mea hope loa, ʻoi aku ka maikaʻi o ka haʻi ʻana i ka hoʻohana ʻana i ka graphene, no ka mea, ua ʻike mua ʻia nā hopena: ua hiki i ka graphene cathode ke piʻi i kahi kiʻekiʻe o 0,2-0,3 kWh / kg a hiki ke hana i nā ʻumi a i ʻole nā ​​haneli haneli o ka hana. nā pōʻaiapuni (!). ʻO ka hōʻike mai Kina he mea hoihoi loa ia ma muli o kona kokoke i Australia a me nā pilina ʻepekema ma waena o nā ʻāina ʻelua. ʻAe, ua hoʻomohala ʻo Zhejiang University i kahi kelepona alumini ion hiki ke hoʻopaʻa ʻia i 1,1 kekona a paʻa i ka 91,7 pakeneka o kona hiki mua ma hope o 250 cycles (kumu).

He mea maʻalahi ka alumini, he pipiʻi ka graphene

Ke hoʻomau nei ka hana ʻana i nā cell ion alumini no nā makahiki no ka mea ʻo ka alumini ka mea hoʻohiki maikaʻi loa e like me ke kahua kūkulu o kahi anode hāʻawi ion. Akā, pono ia i nā electrolytes a me nā cathodes pipiʻi inā makemake mākou e pale iā ia mai ka hoʻopaʻa ʻana me nā mea ʻē aʻe i loko o ke kelepona, no ka mea, hoʻopau koke ia mau mea paʻa i ka ʻōnaehana. Eia naʻe, ʻōlelo ʻo Graphene Manufacturing Group e hoʻokuʻu ia i nā pihi pihi alumini-ion ma hope o kēia makahiki a i ʻole 2022. Manaʻo ʻia e mākaukau nā ʻeke kaʻa i ka hoʻomaka ʻana o 2024..

ʻAʻole ʻoi aku ka maʻalahi o nā pākahi kaʻa e pili ana i nā cell ion aluminika ma muli o ko lākou kiʻekiʻe o ka ikehu. Ua hōʻike ʻo GMG i kēlā ʻAʻohe pilikia o nā pūnaewele ion alumini me nā wela kiʻekiʻe a haʻahaʻa paha, no laila aia kahi manawa ʻaʻole lākou e koi i ka hoʻomaha a hoʻomaha hou.... Eia hou, i ka wā e hiki mai ana e like ko lākou ʻano a hāʻawi i ka volta like e like me nā cell lithium-ion o kēia manawa, no laila hiki ke maʻalahi iā lākou ke hoʻololi ʻia i nā ʻeke pā uila (kumu).

E hoihoi paha kēia iā ʻoe:
